Help with switch statement
Hello I have a copy of my code below. Everything compiles fine its just when the code gets to the switch statement I get an error saying
Exception in thread "main" java.util.InputMismatchException

at java.util.Scanner.nextInt(Scanner.java:2000)
at Sample.main(Sample.java:55)
Something is not working right when the user enters an integer expression. what can I do to fix this?
import java.util.*;
import java.io.*;
// Declare a public class
public class Sample {
public static void main (String[] args){
//Declare Variables
float float0, float1;
int int0, int1;
String mathSign;
char charMathSign;
Scanner sc = new Scanner(System.in);
//Ask user to Enter FLoating-Point Number Expression
System.out.println("Enter a simple floating-point expression: ");
float0 = sc.nextFloat();
mathSign = sc.next ();

Help with Switch statements using Enums?
Hello, i need help with writing switch statements involving enums. Researched a lot but still cant find desired answer so going to ask here. Ok i'll cut story short.
Im writing a calculator program. The main problem is writing code for controlling the engine of calculator which sequences of sum actions.
I have enum class on itself. Atm i think thats ok. I have another class - the engine which does the work.
I planned to have a switch statement which takes in parameter of a string n. This string n is received from the user interface when users press a button say; "1 + 2 = " which each time n should be "1", "+", "2" and "=" respectively.
My algorithm would be as follows checking if its a operator(+) a case carry out adding etc.. each case producing its own task. ( I know i can do it with many simple if..else but that is bad programming technique hence im not going down that route) So here the problem arises - i cant get the switch to successfully complete its task... How about look at my code to understand it better.
I have posted below all the relevant code i got so far, not including the swing codes because they are not needed here...
ValidOperators v;
public Calculator_Engine(ValidOperators v){
stack = new Stack(20);
//The creation of the stack...
this.v = v;
public void main_Engine(String n){
ValidOperators v = ValidOperators.numbers;
*vo = vo.valueOf(n);*
switch(v){
case Add: add(); break;
case Sub: sub(); break;
case Mul: Mul(); break;
case Div: Div(); break;
case Eq:sum = stack.sPop(); System.out.println("Sum= " + sum);
default: double number = Integer.parseInt(n);
numberPressed(number);
break;
//default meaning its number so pass it to a method to do a job
public enum ValidOperators {
Add("+"), Sub("-"), Mul("X"), Div("/"),
Eq("="), Numbers("?"); }
Notes*
It gives out error: "No enum const class ValidOperators.+" when i press button +.
It has nothing to do with listeners as it highlighted the error is coming from the line:switch(v){
I think i know where the problem is.. the line "vo = vo.valueOf(n);"
This line gets the string and store the enum as that value instead of Add, Sub etc... So how would i solve the problem?
But.. I dont know how to fix it. ANy help would be good
Need more info please ask!
Thanks in advance.demo:
import java.util.*;
public class EnumExample {
enum E {
STAR("*"), HASH("#");
private String symbol;
private static Map<String, E> map = new HashMap<String, E>();
static {
put(STAR);
put(HASH);
public String getSymbol() {
return symbol;
private E(String symbol) {
this.symbol = symbol;
private static void put(E e) {
map.put(e.getSymbol(), e);
public static E parse(String symbol) {
return map.get(symbol);
public static void main(String[] args) {
System.out.println(E.valueOf("STAR")); //succeeds
System.out.println(E.parse("*")); //succeeds
System.out.println(E.parse("STAR")); //fails: null
System.out.println(E.valueOf("*")); //fails: IllegalArgumentException

Alrighty, so I have to do this assignment for my Java course, using a switch statement. The assignment is to have the user enter a number (1-5), and have the corresponding line of a poem be displayed. So if the user entered 1, "One two, buckle your shoe" would be displayed. This is what I have and it's giving me a huge problem:
import java.util.Scanner;
public class Poem
public static void main(String[] args);
Scanner kboard = new Scanner(System.in);
System.out.println("Enter a number 1-5 (or 0 to quit).");
int n = kboard.nextLine();
switch (n);
case 1: System.out.println("One two, buckle your shoe.");
break;
case 2: System.out.println("Three four, shut the door.");
break;
case 3: System.out.println("Five six, pick up sticks.");
break;
case 4: System.out.println("Seven eight, lay them straight.");
break;
case 5: System.out.println("Nine ten, a big fat hen.");
break;
default: System.out.println("Goodbye.");
break;
}This is giving me a HUGE string of errors. (Something like 45). I'm wracking my brain here trying to figure this out. Any help is greatly appreciated. Thanks!Well that solved a lot of the errors. Now all I get is this:
--------------------Configuration: <Default>--------------------
C:\JavaPrograms\Poem.java:8: <identifier> expected
System.out.println("Enter a number 1-5 (or 0 to quit).");

Having problem with switch statement..please help
here my question :
GUI-based Pay Calculator
A company pays its employees as executives (who receive a fixed weekly salary) and hourly workers (who receive a fixed hourly salary for the first 40 hours they work in a week, and 1.5 times their hourly wage for overtime worked).
Each category of employee has its own paycode :
? Paycode 1 for executives
? Paycode 2 for hourly workers
Write a GUI-based application to compute the weekly pay for each employee. Use switch to compute each employee?s pay based on that employee?s paycode.
Use CardLayout layout manager to display appropriate GUI components. Obtain the employee name, employee paycode and other necessary facts from the user to calculate the employee?s pay based on the employee paycode:
? For paycode 1, obtain the weekly salary.
? For paycode 2, obtain the hourly salary and the number of hours worked.
You may obtain other information which you think is necessary from the user.
Use suitable classes for the GUI elements. (You can use javax.swing package or java.awt package for the GUI elements.)

HOW CAN I PERFORM THE SWITCH STATEMENT INSIDE THIS CODE TO LET IT FULLY FUNCTIONAL..?
I MUST PERFORM THE SWITCH STATEMENT LIKE IN THE QUESTION..
PLEASE HELP ME..REALLY APPRECIATED...TQhi
A switch works with the byte, short, char, and int primitive data types. So you can simply give the
switch (month) {
case 1:
System.out.println("January");
break;
case 2: {
System.out.println("February");
break;
case 3: {
System.out.println("March");
break;
}where month controlls the flow
moreover u can go to http://www.java-samples.com/java/free_calculator_application_in_java.htm
for reference, just replace the if statement with switch with correct syntax -
Problems with switch statement
He everyone,
i tried to built a page with 4 buttons. Each button is a symbol that contains 2 png´2 which are the the button Designs. If you click on button 1 it should move on the screen. If you click it again it should moves back. and if you click on another button while button1 is active then button1 should move back to starting position and button 2 should move on screen.
i use a switch statement and a variable.
on composition ready i used
sym.setVariable("current","");
to set the Variable
on each button(one of the png inside the symbols) i used:
var current = sym.getComposition.getStage.getVariable("current");
switch (current)
case "" :
sym.play("in");
break;
case button1 :
sym.play("out");
break;
default :
sym.getComposition.getStage.getSymbol(current).play("out");
sym.play("in");
break;
ad each animation of the buttons are labels for the in and out animation. There are also triggers that change the variable current on the stage
sym.getComposition.getStage.setVariable("current","button1");
if i test it inside of a browser and click on one of the button nothing happens.
i´m not sure what´s my mistake.
can anyone help me?
regards
mr.monsenHi,
Some syntax errors in red:
var current = sym.getComposition().getStage().getVariable("current");
switch (current)
case "" :
sym.play("in");
break;
case "button1" :
sym.play("out");
break;
default :
sym.getComposition().getStage().getSymbol(current).play("out");
sym.play("in");
sym.getComposition().getStage().setVariable("current","button1"); -
Problem with switch-statement & ä, ö, ü
Hi all,
I am doing this Java online tutorial right now and have a problem with one of the exercises. Hopefully you can help me:
I have to write a program that determines the number of consonants, vowels, punctuation characters, and spaces in an input line. I found a solution, but have two questions about it:
Im unable to calculate the amount of umlauts (ä, ö, ü). Somehow the program doesnt recognize those characters. Why?
In general Im not very happy with this huge list of cases. How would you solve a problem like this? Is there a more convenient/elegant way?
Thanks in advance!
Write a program that determines the number of consonants, vowels, punctuation characters, and spaces in an input line.
Read in the line into a String (in the usual way). Now use the charAt() method in a loop to access the characters one by one.
Use a switch statement to increment the appropriate variables based on the current character. After processing the line, print out
the results.
import java.util.Scanner;

In general Im not very happy with this huge list of cases. How would you solve a problem like this? Is there a more convenient/elegant way?I've been doing this a lot lately myself evaluating documents with 20 or so million words. Few tips:
1. Regular expressions can vastly reduce the list of cases. For example you can capture all letters from a to z or A to Z as follows [a-zA-Z]. To match a single character in a String you can then make use of the Pattern and Matcher classes, and incorporate the regular expression. e.g.
//Un-compiled code, may contain errors.
private Pattern letterPattern = Pattern.compile("[a-zA-Z]");
public int countNumberOfLettersInString(final String string) {
int count = 0;
Matcher letterMatcher = letterPattern.matcher(string);
while(letterMatcher.find()) {
count++;
return count;
}2. As mentioned above, Sets are an excellent choice. Simply declare a static variable and instantiate it using a static initializer block. Then loop over the String to determine if the character is in the given set. e.g.
//Un-compiled code, may contain errors.
private static Set<Character> macrons = new HashSet<Character>();
static {
macrons.add('ä');
macrons.add('ö');
macrons.add('ü');
public int countNumberOfMacronsInString(final String string) {
int count = 0;
for(char c : string.toCharArray()) {
if(macrons.contains(c) {
count++;
return count;

Thanks in advance.
I read the tut on switch statements. My assignment is asking me to do something that is not detailed in that explanation ;
I have a total of 5 case statements, 1-4 and a default statement. The instructions for them are as follows:
Case 1: If the user enters a 1, display a message that informs users they are correct, as any input canbe saved as a String. Enter the break statement.
Case 2: If the user enters a 2, parse the value into tryInt. Display as message that informs the users they are correct. Enter the break statement.
Case 3. If they user enters a 3, parse the value into tryDouble. Display a message tha t informs users they are correct. Enter the break statement.
Case 4: Set done equal to true. Enter code to display a closing message. Enter a break statement.
Case default: throw a new NumberFormatException.;
Here is the code
import java.io.*;
import javax.swing.JOptionPane.*;
public class MyType1
public static void main(String[] args)
//declaring variables
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;
//loop while not done
while (!done)
try
choice = Integer.parseInt(strChoice);
switch(choice)
case 1:
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 2:
choice = Integer.parseInt(tryInt); JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 3:
choice = Double.parseDouble(tryDouble);
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 4:
done = true; JOptionPane.showMessageDialog(null,"Goodbye!");
break;
As usual Im doing something wrong. Please help.Thanks for your input. The directions for the assignment tells me to first declare the variables.
Begin a while(!done) loop to repeat as long as teh user does not click the Cancel button.
Inside a try statement, enter code to display an input box with three choices.
Type choice = Integer.parseInt(strChoice); on the next line to parse the value for the choice entered by the user.
(HERE THE SWITCH STATEMENT WITH CAST STATEMENTS)
Close the switch statement with brackets
Create a catch statement.
import java.io.*;
import javax.swing.JOptionPane.*;
public class MyType1
public static void main(String[] args)
//declaring variables
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;
//loop while not done
while (!done)
try
String message = "What is My Type:" + "\n\n1) String\n2)Integer\n3)double\n4)Quit the program\n\n";
choice = Integer.parseInt(strChoice);
//test for valid choice 1, 2, 3, or 4
if (choice<1 || choice>4) throw new NumberFormatException();
else done = true;
switch(choice)
case 1:
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 2:
choice = Integer.parseInt(tryInt); JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 3:
choice = Double.parseDouble(tryDouble);
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 4:
done = true; JOptionPane.showMessageDialog(null,"Goodbye!");
break;
catch (NumberFormat Exception e)
JOptionPane.showMessageDialog(null, "Please enter a 1, 2, 3 or 4:", "Error", JOptionPane.INFORMATION_MESSAGE);
}Typing this now, I see I dont have anything in my try statement entering code to display an input box with three choices.
(PS. I know I would write a catch statement for the NumberFormatException, but why would I also write this exception in the case statement also??) -
Help with if statement in cursor and for loop to get output
I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
Here is my cursor:
/*Cursor for Email procedure. It is working Shows userid and the string
You need to update these folders*/
DECLARE
a_user varchar2(200) := null;
v_assigneduser varchar2(20);
v_folderrsn varchar2(200);
v_emailaddress varchar2(60);
v_subject varchar2(200);
Cursor c IS
SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",
trunc(sysdate) - MAX (trunc(fpa.attemptdate)) AS "DAYS PAST"
--MAX (TRUNC (fpa.attemptdate)) - TRUNC (f.indate) AS "NUMBER OF DAYS"
FROM folder f, folderprocess fp, validuser vu, folderprocessattempt fpa
WHERE f.foldertype = 'HJ'
AND f.statuscode NOT IN (20, 40)
AND f.folderrsn = fp.folderrsn
AND fp.processrsn = fpa.processrsn
AND vu.userid = fp.assigneduser
AND vu.statuscode = 1
GROUP BY assigneduser, vu.emailaddress, f.folderrsn, f.indate
ORDER BY fp.assigneduser;
BEGIN
FOR c1 IN c LOOP
IF (c1.assigneduser = v_assigneduser) THEN
dbms_output.put_line(' ' || c1.folderrsn);
else
dbms_output.put(c1.assigneduser ||': ' || 'Overdue Folders:You need to update these folders: Folderrsn: '||c1.folderrsn);
END IF;
a_user := c1.assigneduser;
v_assigneduser := c1.assigneduser;
v_folderrsn := c1.folderrsn;
v_emailaddress := c1.emailaddress;
v_subject := 'Subject: Project for';
END LOOP;
END;
The reason I have included the folowing table is that I want you to see the output from the select statement. that way you can help me do the if statement in the above cursor so that the result will look like this:
emailaddress
Subject: 'Project for ' || V_email || 'not updated in the last 30 days'
v_folderrsn
v_folderrsn
etc
[email protected]......

This table is to shwo you the select statement output. I want to eliminnate the two days that that are less than 30 days since the last update in the last column.

Hi,
First Special thanks to Kglad for the help with the AS1 to AS3 conversion.
I've been able to link up my buttons to play a different frames of the movie. this was my novice way of finally getting the programming to work.
In frame 95 I have
var myLoader:Loader = new Loader();
addChild(myLoader); var url:URLRequest = new URLRequest("page1.swf");
myLoader.load(url);
in frame 165:
var myLoader1:Loader = new Loader();
addChild(myLoader1); var url1:URLRequest = new URLRequest("page1.swf");
myLoader1.load(url1);
My buttons link to 116 which plays a frame and loads ^
in frame 226: removeChild(myLoader).
But if the user has looped back into home from another part in the movie clip then it would need to remove myLoader1 instead of myLoader.
I'm guessing there is some really dynamic way to solve the programatic nightmare i'm developing, but I'm really novice.
So what i need is an if statement for frame 226
That would do something:
if(myLoader <> null
removeChild(myLoader)
else(
removechild(myLoader1)
Anyone have a method for this?yes, you can use the same urlrequest but just change its url property:
// initialize, for example in frame 1. this is done once and never again:
var loader:Loader=new Loader();
var urlR:URLRequest=new URLRequest();
// then in frame 2, for example:
urlR.url="page1.swf";
loader.load(urlR);
// in frame 20, for example:
urlR.url="page2.swf";
loader.load(urlR);
// in frame 30, for example:
urlR.url="page3.swf";
loader.load(urlR);
//etc. if you're loading any swfs that play streams (sound or video), you'll want to add some code to this. -
Here's my dilemma,
I'm trying to write a program that takes a user input ZIP Code and then outputs the geographical area associated with that code based on the first number. My knowledge of Java is very, very basic but I was thinking that I could do it with the charAt method. I can get the input fine and isolate the the first character but for some reason the charAt method is returning a number like 55 (that's what I get when it starts with 7). Additionally, to use the charAt my input has to be a String and I can't use a String with the switch statement. To use my input with the Switch statement I have to make the variable an int. When I do that however, I can't use the charAt method to grab the first digit. I'm really frustrated and hope someone can point me in the right direction.
Here's what I have so far:
import java.util.Scanner;
public class ZipCode
public static void main(String[] args)
// Get ZIP Code
int zipCodeInput;
Scanner stdIn = new Scanner(System.in);
System.out.print("Please enter a ZIP Code: ");
zipCodeInput = stdIn.nextInt();
// Determine area of residence
switch (zipCodeInput)
case 0: case 2: case 3:
System.out.println(zipCodeInput + " is on the East Coast");
break;
case 4: case 5: case 6:
System.out.println(zipCodeInput + " is in the Central Plains area");
break;
case 7:
System.out.println(zipCodeInput + " is in the South");
break;
case 8: case 9:
System.out.println(zipCodeInput + " is int he West");
break;
default:
System.out.println(zipCodeInput + " is an invalid ZIP Code");
break;

Alright, I've successfully isolated the first number in the zip code by changing int zipCodeChar1 into char zipCodeChar1. Now however, when I try to run that through the switch I get the default message of <ZIP> is an invalid ZIP Code. I know that you said above that switch statements were bad so assume this is purely academic at this point. I'd just like to know why it's not working.
import java.util.Scanner;

String zipCodeInput;
char zipCodeChar1;

System.out.println("zipCodeInput is: " + zipCodeInput); // Retuns 31093
zipCodeChar1 = zipCodeInput.charAt(0);
System.out.println("zipCodeChar1 is: " + zipCodeChar1); // Returns 3
// Determine area of residence
switch (zipCodeChar1)

When you print the char '7' as a character you will see the character '7', but char is really a numeric type: think of it as unsigned short. To convert '0'...'9' to the numbers 0...9, do the math:
char ch = ...
int digit = ch - '0';edit: or give your cases in terms of char literals:
case '0': case '2': case '3': -
Can someone explain to me what a return statement does exactly and how I would use it to return a value in the follwoing type of program.
Its a array making program that allows up to 25 values with the value 0 stopping the method. I need to be able to display the how many usable values the user input (anywhere from 1-25).
To do this I need to use a return statement, correct? if so, how do utilize it correctly if it is nesasary I will post the code itself.Heres what I have for the code...
To simplify amounbt of typing(I wrote program in telnet) The beginning is a set of options using switch statement. 4 choices, 1)new data. 2) list the data 3) change the data and 4) exit.
For the new data I need to have the user input up to 25 values or stop at any time by entering 0. the values also cannot be greater than 12000 or less than -12000. it should also return the number of usable values in the array. The return statement is what I am having trouble with.
Code...
static int NewData(double a[]) //This part is not changeable
{ int 1;
for(i=0; i<25; i++)
{ System.out.print("Enter Element"+(i +1)+ "- ");
a=MyInput.readDouble();
if (a[i]>12000 || a[i]<-12000)
{System.out.println("the last value is not valid");
break;}
if (a[i]==0)
break;
} return i;
As of right now the method functions as is but two things need to be changed or added. If possible the program should now break if the user inputs an element greater than 12000 or less than -12000, it should just reset to the integer they were on. Also, how do I get the return value to display something? have i used it correctly to show the number of usable values ithe user entered? -

For example, if I had no idea how to test whether a file exists, I would just scan the big list of classes on the left for names that sound like they might include File operations. Hey look, File! Then I'd look at all of File's methods for something that tests whether it exists or not. Hey, exists! Then if I still couldn't figure out how to use it, I'd do a google search on that particular method. -
Help with dynamic statement returning values into collection

By the way, I don't see why you are using dynamic SQL here. Static SQL will do just fine. And so you can literally copy Adrian's setup.
