Please help me, boolean function
Hello everyone, this is my first post in this forum. I have this function but I cant get it to work because I get this "missing return statement". Im desperate now, I cant figure how to fix it. Please help me.
public static boolean es(String inst) { // Verificador de validez
int ad=inst.indexOf("ADELANTE");
int at=inst.indexOf("ATRAS");
int iz=inst.indexOf("IZQUIERDA");
int de=inst.indexOf("DERECHA");
int bo=inst.indexOf("BORRAR");
int ho=inst.indexOf("HOGAR");
double numero;
try {
if ((ad==0)&&(inst.charAt(8)==' ')) {
numero = Double.parseDouble(inst.substring(9));
if (numero>0)
return true;
else return false;
if ((at==0)&&(inst.charAt(5)==' ')) {
numero = Double.parseDouble(inst.substring(6));
if (numero>0)
return true;
else return false;
if ((iz==0)&&(inst.charAt(9)==' ')) {
numero = Double.parseDouble(inst.substring(10));
if ((numero>0)&&(numero<360))
return true;
else return false;
if ((de==0)&&(inst.charAt(7)==' ')) {
numero = Double.parseDouble(inst.substring(8));
if ((numero>0)&&(numero<360))
return true;
else return false;
if (bo==0) return true;
if (ho==0) return true;
else return false;
catch (NumberFormatException ex) {
}The objective of this function is to check if the user entered one of these words: "adelante", "atras", "izquierda" or "derecha" followed by a positive number. Thank you in advance for your help.
you need to have a return statement at the very end of you method.
here's a rewrite of what you provided...instead of a bunch of returns everywhere, i set a variable to return. i also put else if statements instead of if since you only want to see if one of the instances exist
public static boolean es(String inst) { // Verificador de validez
int ad=inst.indexOf("ADELANTE");
int at=inst.indexOf("ATRAS");
int iz=inst.indexOf("IZQUIERDA");
int de=inst.indexOf("DERECHA");
int bo=inst.indexOf("BORRAR");
int ho=inst.indexOf("HOGAR");
double numero;
boolean answer = false;
try {
if ((ad==0)&&(inst.charAt(8)==' ')) {
numero = Double.parseDouble(inst.substring(9));
if (numero>0)
answer = true;
else answer = false;
else if ((at==0)&&(inst.charAt(5)==' ')) {
numero = Double.parseDouble(inst.substring(6));
if (numero>0)
answer = true;
else answer = false;
else if ((iz==0)&&(inst.charAt(9)==' ')) {
numero = Double.parseDouble(inst.substring(10));
if ((numero>0)&&(numero<360))
answer = true;
else answer = false;
else if ((de==0)&&(inst.charAt(7)==' ')) {
numero = Double.parseDouble(inst.substring(8));
if ((numero>0)&&(numero<360))
answer = true;
else answer = false;
else if (bo==0) answer = true;
else if (ho==0) answer = true;
else answer = false;
catch (NumberFormatException ex) {
answer = false;
return answer;

Please help regarding method/function sign up validation with mysql jdbc.
HI guys,
I am have been fixing this problem for days, hope that someone could help me find the bug on my code.
I have 3 files:
1.WithAuth.java - for database jdbc mysql connection
2.WithAuthMet.java - method that will read any variables that will be passed to it. this method is waiting for two variables, a and b. a for userName and b for userPassword.
3.WithAuthTest.java - the testing class, this is where i declare my sample control data to test the database connection and query.
here's the actual codes:
WithAuth.java
package com.Auth;
public class WithAuth {
static String userName = "root";
static String userPassword = "";
static String databaseUrl = "jdbc:mysql://localhost:3306/javatowebservice";
static String userQuery = "select * from userlogin";
}WithAuthMet.java
- this is where the error is and where I messed up.
package com.Auth;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class WithAuthMet extends WithAuth {
public void connect(String a, String b)throws Exception{
//try {
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
Connection conn = DriverManager.getConnection (databaseUrl, userName, userPassword);
Statement stat = conn.createStatement();
String query = userQuery;
ResultSet result = stat.executeQuery(query);
System.out.println("Result(s): ");
while (result.next ()){
int i = result.getInt("userId");
String name=result.getString("userName");
String password=result.getString("userPassword");
//System.out.println("test data:"+a);
if(a.equals(name.equals("userName"))&& b.equals(password.equals("userPassword"))){
System.out.println("User is Valid");

System.out.println("test data:"+name);
System.out.println("test data:"+password);
System.out.println("test data:"+a);
System.out.println("test data:"+b);
//conn.close();
// }catch(Exception e){
//System.out.println("Exception is ;"+e);
//System.out.println("Exception is ;");
// if(a.equals(name.("userName"))
// && password.equals(password.equals("userPassword"))){
// System.out.println("User is Valid");
// else{

WithAuthMet CTD = new WithAuthMet();
String a = "dan";
String b = "password";
//CTD.connect(String name,String password);
CTD.connect(a, b);
//return connect;

This is one line that is wrong
if(a.equals(name.equals("userName"))&& b.equals(password.equals("userPassword"))){You have 'a' and 'b which are Strings
and you are comparing them [using equals()] with the boolean return from another set of equals() invocations.
String equals boolean will always be false (well, maybe not if the String is "TRUE" or "FALSE" - and you would need some more boilerplate to make that work). -

Please help me : SUBSTR function in Oracle 6i
Dear all people!
I have a problem with SUBSTR as follow:
my code:
declare
string1 varchar2(300);
string2 varchar2(65);
begin
string1 := ....
string2 := substr(string1,1,60);
end;
when i run program in debug
at command "string2 := substr(string1,1,60);" it raise error ORA-06502;
Please tell me how to assign substr(string1,1,60) to string2 (max length of string2 is 65);
I'm looking to forward to receiving your response!
Thank you very much;The question was simple:
I am trying to do is bring in anything after the * in the Id column no matter how long the name is before the * but my calculation is way off L:
Here is an example of what my data would look like but what I need it to do:
Id NEW COLUMN
TNET*231333 231333
AMER*29283893.2 29283893.2
TNEY*21893838 21893838
Do you know how to create this calculation?
Answer: SUBSTR(id,INSTR(id,'*',1)+1,999)
this was emailed to me from someone on here saying "try to see if this helps" and it did that's why i said thank you. -

Using a tweening function as a rollover. Please help me restore functionality!
Ok, I have a movieclip with 3 different tweens applied to it
by a few functions. The first tween happens on rollover and makes
the movieclip a little bigger, the second tween happens on rollout
and makes it smaller. The third tween happens on release and makes
the clip much bigger. However, when the user clicks the movie clip
it deletes all of the rollover/rollout/onrelease commands so that
the user can interact with a swf which is loaded into the mc.
Here's my code so far:
//Tweens//
function grow(who) {
who.onEnterFrame = function() {
if (this._xscale<40) {
this._xscale += 5;
this._yscale += 5;
if (this._xscale == 40 && this._yscale == 40) {
delete this.onEnterFrame;
function shrink(who) {
who.onEnterFrame = function() {
if (this._xscale>16.5) {
this._xscale -= 5;
this._yscale -= 5;
if (this._xscale == 16.5 && this._yscale == 16.5) {
delete this.onEnterFrame;
function growBigger(who) {
who.onEnterFrame = function() {
if (this._xscale<100) {
this._xscale += 5;
this._yscale += 5;
if (this._xscale == 100 && this._yscale == 100) {
delete this.onEnterFrame;
//End Tweens//
loadMovie("preloader.swf", "preloader_mc");
preloader_mc._xscale = 21;
preloader_mc._yscale = 20;
this.onRollOver = function() {
grow(this);
this.onRollOut = function() {
shrink(this);
this.onRelease = function() {
delete onRollOver;
delete onRollOut;
delete onRelease;
_root.MkXpos = _root.touristsMark._x;
_root.MkYpos = _root.touristsMark._y;
_root.pan(_root.mapContainer_mc);
growBigger(this);
_root.mapContainer_mc.map_mc.dragger_mc._visible = false;
_root.drag = false;
All of this works just fine. My only problem is that when the
user exits the loaded swf I want the button to shrink back down and
have its functionality restored. Basically when someone clicks the
exit button on the external swf it runs the shrink(who) function
and shrinks everything back down. I put a line of code into the
shrink function when it checks to see if "who" is at 16.5, which
looked like this:
if (this._xscale == 16.5 && this._yscale == 16.5) {
this.onRollOver = function = () {
grow(this);
delete this.onEnterFrame;
However, that didn't restore the functionality. Any help
would be greatly appreciated! I'm a poor student on a deadlineI'm such a moron. I never put in a trace command to see if
the last line of my shrink command was getting executed. It turns
out the movie doesn't scale perfectly to 16.5 but instead goes to
16.49etcetc. As a result that last line wasn't being executed. Now
everything works. But I was wondering if you guys could think of a
nice way to compartmentalize all of this code, like maybe store it
all in a variable or something, so I can attach it to several
different movie clips? -

Please HELP iPod somewhat functional
My 4th gen nano is having some issues. It will not load past the language selection screen. I can reset with the center and menu keys which leads me to believe that it's not the click. but once it get to the language screen none of the buttons work. Also if u plug in the headphones and shake it, it will play music and shake to shuffle. Once the screen goes to sleep or whatever shake to shuffle doesn't work. I have restored it with the latest iTunes but it is still not working.
Can someone plz help me, it's out o warranty and I can't afford to buy another one. There must be a way to fix this. Thanks in advance for any help/suggestions.You have to sync your iTunes library content to the iPod.
See this iPod tutorial video.
Have a nice day! -

Please help---merge function for two arrays.
I am trying to create a merge function that merges two sorted arrays into a third array. I know what I am supposed to do, at least in theory, but I have been completely unsuccessful with actually getting the code to work. Since it is private, you can't directly access the arrays, you have to just reference them. could someone please help me out.
import java.io.*;
class OrdArray
private long[] a;
private int nElms;
public OrdArray(int max)
a = new long[max];
nElms = 0;
public int size()
{ return nElms;}
public int find(long searchKey)
int lowerBound = 0;
int upperBound = nElms-1;
int curIn;
while(true)
curIn = (lowerBound + upperBound) / 2;
if(a[curIn]==searchKey)
return curIn;
else if (lowerBound > upperBound)
return nElms;
else
if(a[curIn] < searchKey)
lowerBound = curIn + 1;
else
upperBound = curIn - 1;
public void insert(long value)
int j;
for(j=0; j<nElms; j++)
if(a[j] > value)
break;
for(int k=nElms; k>j; k--)
a[k] = a[k-1];
a[j] = value;
nElms++;
public boolean delete(long value)
int j = find(value);
if(j==nElms)
return false;
else
for(int k=j; k<nElms; k++)
a[k] = a[k+1];
nElms--;
return true;
public void display()
for(int j=0; j<nElms; j++)
System.out.print(a[j] + " ");
System.out.println("");
public void merge(OrdArray array, OrdArray array1)
}//this is the start of the merge function. I am stuck and not real sure where to go from here.
public long getElm(int index)
return a[index];
}//end class OrdArray
class OrderedApp
public static void main(String[]args)
int maxSize = 100;
OrdArray arr, arr1, arr2;
arr = new OrdArray(maxSize);
arr1 = new OrdArray(maxSize);
arr2 = new OrdArray(maxSize);
arr.insert(77);
arr.insert(99);
arr.insert(44);
arr.insert(55);
arr.insert(22);
arr1.insert(88);
arr1.insert(11);
arr1.insert(00);
arr1.insert(66);
arr1.insert(33);
arr2.merge(arr, arr1);
arr.display();
System.out.println("--------------------");
arr1.display();
System.out.println("--------------------");
arr2.display();
}If I use ArrayList<Long>, would I have to change private long[]a to ArrayList<long>, cause if so, I am not able to do that.
I am supposed to add a merge() method to megre the two source arrays into an ordered destination array.
public void merge(OrdArray array, OrdArray array1)
mergeSize = array.nElems + array1.nElems;
int i = 0;
int j = 0;
int k = 0;
while (i = 0; i < array.nElems; i++) {
if {array.getElm(i) < array1.getElm(j)
//how do you move to the next set of values
//and to move which variables are incremented
//how do you test if the flush loop should be called, hint if( == )
while (j = mergeSize - array.nElems; j <= mergeSize; j++) {
this.a[j] = array1.a;
//again how do you move to next value and placeholder
//which indices are incremented
//copy/paste and change the variables for the other value being smaller
public long getElm(int index)
return a[index];
this is all I have started, but i don't really understand all the comments because I haven't used java in a long time. Like I said, I understand what needs to be done and what order to do it in, but getting the code down to do that is really rough -
My LCD Screen burned out, but the computer still works. I currently have it connected to an HDTV via, Mini DVI to VGA, VGA to VGA on the tv. Problem is, I can't get the function bar (maybe not the right term) or the bar at the bottom with all my programs on it. I get my screen saver and have managed to drag (by sheer luck since I can't see anything on my iMac screen) some of my pics I had on my desktop over, but nothing else. Please help!
Hello
you should have on your key board "mirroring key" , or F7 on old keyboard
for now your tv is an extended screen for your imac not a miror , so you can not see menue barre on top of screen
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8525.html
HOPE you are in 10.6
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8525.html
"On some keyboards, you can press the F7 key, or Command-F1, as a shortcut to turn video mirroring on or off."

}Hi All,
I have created below script. But there is some problem which I am unable to find.
My two check boxes 1) Find double Spaces and 2) Find Unused Paragraph Styles is not running in this script. When I run this script on ESTK it gives error "Cannot handle the request because a modal dialog or alert is active."
But every function is working fine as a single script. Please check.
Thanks in advance for your effort on this.

I have tried but couldn't succes.
