1 java test = OCP?

I am just wondering what Oracle was thinking when they decided that taking 1 java test should get an OCP credential.
When I got my first OCP, as Oracle8i DBA, I had to pass 5 tests. DBAs now have to pass 3 tests and take a course.
If someone wants to certify as a Linux Administrator, they can take 2 tests, and that's only for the OCA.
But if anyone takes the Java Programmer test, that's OCP? I passed the Java Programmer test several years ago (for Java 2), but I would never describe myself as a good java programmer; I only knew some basics.
It seems like there's some inequity here, that makes the OCP and OCM levels easily obtainable for some (java programmers), and more challenging for others (DBAs).

I am currently fairly busy, and the java certs are not my scene, and I haven't reseached sun info on this, but I am concerned, perhaps unnecessarily, about the integration of Sun Java Certs. under the Oracle wing.

Java Test Help. Very little experience

Ok, first off I am taking a Java test for my school's computer science team. I was just placed on the team because they needed an extra person, so my Java experience is close to 0. I would just like to know how to find out some of the answers and what some things mean in the following questions:
1: What is the Sum of 123(subscript16) and DEF(subscript16)
The answer is F12(sub16).
What I need to know about this is how 123 and DEF = F12.
2. Here is the code:
int accum = 0;
for(int i = 1; i <= 25; i++)
accum = accum + 1;
System.out.print ( sub ) ;
The answer is 25. What do these terms mean like accum and i++? How would you get this answer?
3. They are asking what the output would be. Here is the code:
double b = 1.5;
b = b * 2 + 5 / 2;
System.out.println ( b ) ;
The answer is 5.0 What does double b mean and how would you find the answer to that?
4. They are asking for what the output would be. Here is the code:
boolean p = false;
boolean q = true;
System.out.print ( !p && !q ) ;
System.out.print ( " " ) ;
System.out.print ( ! (p && q) );
The answer is false true. I know that boolean has something to do with logic, but I do not understand this question.
Thanks a ton if you can help me. I'm just trying to know a couple of things so I can make a better score on the test. I know it would be easier if I learned step by step, but I am limited on time and any shortcuts and hints will be helpful.
Thanks.

The answer is 25.No it's not. You must not have copied the problem correctly. Either that or it's a stupid trick question. sub hasn't been defined there.

Just go learn step-by-step.

Runtime.getRuntime().exec(java test)

Hi,
As part of a thesis for college, I am trying to execute a test java program. The program executes okay and I can read the results okay.
Sample code.
process = Runtime.getRuntime().exec("java test");
InputStream iOutStream = process.getInputStream();
InputStream ErrorStream = process.getErrorStream();
However, I need to be able to execute a progam that reads a parameter from the screen. I tried to pass a parameter file but it doesn't work.
process = Runtime.getRuntime().exec("java test <input.txt");
I also tried just passing the parameters as a string array but it doesn't work either.
process = Runtime.getRuntime().exec("java test 2, 2");
Is there any other way that I can get the process to accept parameters?
My deadline is looming so any help would be greatly appreciated.
Thanks

I think you are waiting when reading the output before you write to the stream until it becomes NULL or -1. That will never finish if the program you execute is expecting input!
See a working example:
This class does nothing than print a line on the console, then waits for a line of input, then prints the result again on the console. This is the class you'd execute from some other java code:
import java.io.*;
public class Input {
    public static void main(String args[]) {
        try {
            System.out.println("Before input");
            BufferedReader r = new BufferedReader(new InputStreamReader(System.in));
            String s=r.readLine();
            System.out.println("Got line : " + s);
        } catch(Exception e) {
                System.out.println(e.getMessage());
}The following 'controls' the input-test class above, so compile the classes and execute the following one:
import java.io.*;
import java.lang.*;
public class test {
    public static void main(String args[]) {
        try {
            Process p = Runtime.getRuntime().exec("java Input");
            BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));
            BufferedWriter w = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
            String s=r.readLine(); // You cannot read until NULL because that will not happen before you have 'input' something
            System.out.println("Got: " + s);
            w.write("cvxcvxcvx\n\r");
            w.flush();
            System.out.println("waiting result:");
            while( (s=r.readLine()) != null) { // read until finished.
                System.out.println("after : " + s);
        } catch(Exception e) {
                System.out.println(e.getMessage());
}

Java test class

Hello,
have a problem with writing test class in Java for Chat testing.
So, I need to simulate 1000 Users who connected to chat server(PHP).
If I understand, i have to make one thread for each user and send request to the chat server, say for each message I give 10 sec.
Any suggestions?
Thx a lot.
PS: Jnewbe.

Not to disagree with Noviato's suggestions, which are all excellent pointers, but I do want to point out that what you are trying to do is a 'hard problem'. To really load test a system, you normally need to buy commercial software. The problem is that spinning off threads (all of the same priority, and especially a thousand of them) will almost certainly lead to starvation. The commercial programs go through a lot of hoops to create dedicated processes (instead of threads) and ensure the operating system executes them properly.

I need help on a java test

I'm just learning java and my teacer likes giving us tests on stuff he never taught us... I'm not asking for you to give me ther answers but just at least explain what this stuff means
he gave us a program then 16 questions about it
All I know is that the prgram is a class that takes students names and test scores and finds there averges and studd like that
ok heres the program
// Solution 5.1
/* Student.java
Manage a student's name and three test scores.
public class Student {
//Instance variables
//Each student object has a name and three test scores
private String name; //Student name
private int test1; //Score on test 1
private int test2; //Score on test 2
private int test3; //Score on test 3
// Default constructor -- initialize name to the empty string and
// the test scores to zero
public Student() {
name = "";
test1 = 0;
test2 = 0;
test3 = 0;
//Aditional constructor -- initialize the name and test scores
//to the values provided
public Student(String nm, int t1, int t2, int t3){
name = nm;
test1 = t1;
test2 = t2;
test3 = t3;
//Aditional constructor -- initialize the name and test scores
//to match those in perameter s.
public Student(Student s){
name = s.name;
test1 = s.test1;
test2 = s.test2;
test3 = s.test3;
//Other Methods
public void setName (String nm){
//Set a students name
name = nm;
public String getName(){
//Get a students name
return name;
public void setScore (int i, int score){
//Set test i to score
if (i == 1) test1 = score;
else if (i == 2) test2 = score;
else test3 = score;
public int getScore (int i){
//retrieve score i
if (i == 1) return test1;
else if (i == 2) return test2;
else return tes3;
public int getAverage(){
//compute and return the average
int average;
average = (int) Math.round((test1 + test2 + test3) / 3.0);
return average
public int getHighscore(){
//determine and return the highest score
int highScore;
highscore = test1;
if (test2 > highscore) highscore = test 2;
if (test3 > highscore) highscore = test 3;
return highscore;
public String toString(){
//Construct and return a string representation of the student
string str;
str = "Name: " + name + "\n" + // "\n" denotes a newline
"Test 1: " + test1 + "\n" +
"Test 2: " + test2 + "\n" +
"Test 3: " + test3 + "\n" +
"Average: " + getAverage();
return string;
Ok so theres the prgram the Questions are:
1. Identify the four structural elements of the student class prgram
2. Why did I omit the clause extends <some class> in my program
3. Explain Class hierarchy
4. Why are instance variables always declared to be private
5. What would happen if I declared them public
6. What happens if I omit it completely
7. Identify the instance variables in student class program
8. What does the constructor method do in the student class
9. Why didn't I declare and intalize my variables at the same time
10. Why do I use so many comments in this program
(I actually know the answer to this one)
11. Why do I need a default constructor
(what the crap is a constructor?)
12. Why did I provide additional constructors
13. In Additional constructor section, explain the following code:
name = "";
name = nm;
14. Explain Chaining and where did I place it in the student class program
15. List 2 visibility modifiers in this program
16 Rewrite the student class to exclude the "\n" in t the toString section
And that is it. I seriously don't know what any of those questions mean PLEASE HELP!

I came here at Sun because my Norton kept saying
At Work Rendering/shell/print to/command refers to invalid command C/docset/application data/sun/java/deployment/cache/6.0
When I got here it ran a test and said I needed to update
http://java.com/en/download/manual.jsp
and took me to the download page, I installing the update they gave me and it said
Installer cannot proceed with the current internet connection settings
So I downloaded the offline one and this is what came up (its not all there, the forum only takes 5000)

Java from Apple vs Sun Java test site

I know the last Java update that came out was:
http://www.apple.com/support/downloads/javaformacosx105update1.html
About Java for Mac OS X 10.5 Update 1
This Java for Mac OS X 10.5 Update 1 adds Java SE 6 version 1.6.0_05 to your Mac. This update does not replace the existing installation of J2SE 5.0 or change the default version of Java.
Why then, when you goto test Java version at Sun you get:
Jave 1.5.0_13
I thought the update raised the version number?

Why then, when you goto test Java version at Sun you get:
Jave 1.5.0_13
Because that is the default version of Java on the Mac, just like the message on the site told you.

Novice Java Test- please help!

hi I'm new to java and am required to know how to program a certain problem.
please any help is much appreciated. If you can solve the problem that would be nice or if you could tell me how to go about solving it that would be fine too.
here's the problem:
"1. Write a class UniDBug that models a bug moving along a horizontal line, the x number line. The bug moves either to the right or left. Initially, the bug moves in the direction it is facing, but it can turn to change its direction. In each move, its position changes by one unit in the current direction. Provide a constructor and default constructor. (Default constructor not shown)
Public Bug(int intialPosition, int facingDirection)
// facingDirection 1 means to the left, and 2 means to the right
and the following methods:
public void turn()
public void move()
public int getPosition()
2. Write the test program for this class with two bugs, *redBug*, and *blueBug* facing each other, one starting at position 15 and the other at position 3. They should take enough steps to both bugs meet at location 23. Include a print statement whenever a change happens and make sure you identify the bug and the location."
again any help is much appreciated
thank you for your time

thx im gonna do that right now:
"public class UniDBug
     Public Bug(int initialPosition, int faceingDirection);
     UniDBug myBug = new UniDBug();
     public void myBug.drive(100);
     public void move();
          public int getPosition(x);
               position=3;
                    public void turn(1,2);"
obviously, it needs a lot of work

OCA Java Programmer & OCP Java Prgrammer

Hi,
I saw in Oracle site that is is mandatory to get OCA(Associate) Java Programmer before the OCP(Professionnal) Java Prgrammer. but one of my friends is going to pass the OCP Java Prgrammer exam directly without going through the OCA.
Please i want to know if there is a possibility to get the OCP directly, for example for SE6 or SE7.
regards.

You friend can certainly take the exam *1Z0-804 Java SE 7 Programmer II* without having first taken *1Z0-803 Java SE 7 Programmer I*
He will find at that point that Oracle won't give him a certification until he goes back and passes the 1Z0-803 exam. There is a difference between passing an exam and becoming certified. To pass an exam, you schedule it at Pearson-VUE and answer enough questions correctly. Pearson will be happy to allow you to take any exam that you are willing to pay for.
To gain a certification, you have to complete all of the guidelines laid out on the Oracle Education website.

Java testing method

Hi,
I have finished writting a java program.I am going to test it now.I have written test.java and done lots of if and else statements to check if output is as expected.Is this correct and OK?
Is JUnit neceasarily the only correct way to test a program?I aint comfortable with JUnit.
Thanks

How well does it tell you what failed?
Is JUnit neceasarily the only correct way to test a program?I aint comfortable with JUnit.You could use a different testing framework, or something you throw together yourself.
Or you could spend some time and get comfortable with JUnit. IMO it is well worth your time.

Java test from brainbench

Hi all. Within three months I need to pass a test from http://www.brainbench.com
Who knows something about these guys? What will be in the test?

Brainbench test are flawed and not a good resource for testing.
Brainbench has a good marketing plan and have been able to grow a client base from this. Their instructional designers, however, leave much to be desired and don't have a deep understanding of the subject matter. It seems as though Brainbench doesn't have a good set of subject matter experts on staff.
What will be in the test?
If you truly know your stuff, you will find a range of typographical errors, subjective topics, questions with multiple correct answers that ask for a single correct answer, questions with no correct answers, flat out illogical questions, and design questions that have no "best" answer but depend upon context and are not appropriate for multiple choice format.
If you don't know your stuff, you will just find a series of questions that on the surface seem like a good test.
If you are HR staff or a technical recruiter, don't bother wasting your money on Brainbench assessments.
If the organization is depending upon Brainbench assessments for hiring, this indicates that they do not have the appropriate skills in-house to adequately perform a technical skills assessment.
And they most likely are unable to indentify the flaws in the Brainbench assessment questions, if they even read them.
As mentioned, Brainbench is succesfully able to sell their services to organizations that do not have significant in-house Java-based software engineers.
Organizations that do have significant Java-based software engineers, most likely are not paying Brainbench to do their assessment.

Java testing

I am trying to test one of my classes through the console. Some of the main class is (not all methods included)
import java.util.*;
public class Aircraft {
    private ArrayList<Passenger> passengers;

    public boolean addPassenger(Passenger element) {
        try {
            if (passengers.size() < 250 && aircraftWeight < maxWeight) {
                calcPassengerFare(element);
                aircraftWeight += element.getTotalPassengerWeight();
                passengers.add(element);

                         System.out.println(pas.toString());
                    } else {
                       break;
          if(number==2){
               for (int x = 0; x < 52; x++) { //Invalid Weight - Error Thrown
                    if (air.addPassenger(pas)){
                         System.out.println(pas.toString());
                    } else {
                       break;
          public int textMenu()
          int choice = inputInt("\n1: Test passenger charging " + "\n" +
                                     "2: Test Aircraft Weight " + "\n" +
                                     "3: Test Aircraft Seat Numbers ");
          return choice;
}The problem is like so. Say if i choose option 2, check a valid weight....it works, check an invalid weight....it works, check a valid weight again....it dont work. This is because the ArrayList is never being reset therefore when i check it again it will be overweight. That is why i added a reset method in my Aircraft class. However, i add this method into all the methods in my tester, but i still have the same problem. i have also added the reset into a loop, but still the same again. What would be the best way to reset the list after every test?
cheers

The idea is to actually provide a test to the tutor, so in essence it might be best to not allow input and too run each test off a timer. Ask your tutor if he wants that sort of testing. I find that one spends more time fiddling with menus and console input that with the actual code you meant to test, so such an approach seems silly to me.
JUnit looks interesting. Just wondering, if i use JUnit, it would need to be set up on the tutors computer in order for him to perform the test, wouldnt it?All you need is the JUnit jar.

1 java test = OCP?
