Basically I have two classes:

public class abc123 {
public static void main(String[] args) {

int val1 = 1, val2 = 2, sum;

cba abc = new cba();

sum = abc.xcalc(val1, val2);
}

}
____________

public class cba {
public int xcalc(int z, int y)
{
return z + y;
}
}

________________

when I compile both on Sun Java Studio creator and try to run them I get an error:
java.lang.NoClassDefFoundError: class2/abc123
Exception in thread "main"
Java Result: 1

If I run it off Jcreator it runs fine...

could someone pelase helP?

java_roshan

What are you running through Jcreator? (the class file?)
I hope you have saved the file with the name of the class where main function resides.

This error is more common for committing mistakes with the above procedure. It shouldn't be anything else (AFAIK)

well one class is called abc123, the other is called ruff.

When I compile and run them using jcreator it works fine, when I do the same in Sun Java Studio it gives me that error...

First, please you code tags for your code. second, Sun Java Studio is really slow and why are you using 2 IDE at once. Third place cba class within your main class.

Call this file "Abc.java"
[PHP]
public class Abc
{
public static void main(String[] args)
{

cba abc = new cba();
int val1 = 1, val2 = 2, sum;
sum = abc.xcalc(val1, val2);
}
private class cba
{
public int xcalc(int z, int y)
{
return z + y;
}
}
}
[/PHP]
Compile and run it, this will work fine regardless of any type of Java IDE

I'm not using 2 IDE's, I'm only using Sun's IDE, but it's not working on it, but its working on jcreator.

I also want it to run from two serperate class files, not just one...

ReggaetonKing

Either you must have the two files in the same directory or just define the cba class in a packages.

[PHP]
package mypackage.classes;
class cba
{
public int xcalc(int z, int y)
{
return z + y;
}
}
[/PHP]

Then import that package where you would like to use that class
[PHP]
//main class
import mypackage.classes;
public class Abc
{
public static void main(String[] args)
{

cba abc = new cba();
int val1 = 1, val2 = 2, sum;
sum = abc.xcalc(val1, val2);
}
}
[/PHP]

If this doesn't work, your IDE is f*cked up!

I just don't understand why Sun's doesn't work werein jcreator does (also the linux based compiler at school also works)...

ReggaetonKing

Did you do what I said to do?

tumbleTetris

well I haven't read up on packages just yet, its actually in the next chapter, so I'm going to read it and see how it works and what to do exactly.

If the packaging doesnt work I'll come back

ReggaetonKing

It should, if not, your IDE is the problem then.
