Legal Arguments for If Statements

[Unni Kainila]

I was playing a bit with an example in K&B's exam book (page 215. i think the sample in the book misses a closing paranthesis).
A slight variant of the sample is given below:

public class RunMain {
    public static boolean doStuff() {
return true;
    }
    public static void main(String[] args) {
int y=5;
int x=2;
//check1
if( (((2>3) && (5<2)) | doStuff() )) {
System.out.println("true-1");
}
//check2
if( (((x>3) && (y<2) ) | doStuff() )) {
        System.out.println("true-2");
}
//check3
if( (((2>3) && (5<2)) | (true) )) {
System.out.println("true-3");
}
//check4
if( (((x>3) && (y<2) ) | (true) )) {
System.out.println("true-4");
}
    }
}

When I run this code, the output is:
true-1
true-2
true-3
I wonder why "true-4" is not printed

Hi Unni,
When I run this code it does print all four lines...

Hey Unni,
I just copied and pased that code into a test class and it does print all:
C:\tmp>java Test
true-1
true-2
true-3
true-4
C:\tmp>

Friends,
Looks like my java IDE problem. It is using jdk1.3 too!
I compiled and run it from command prompt with jdk1.4.1. I got all four lines of output.
Sorry for the confusion, thanks for your help.
How do you guys test your code...command prompt? Or do you use java IDEs? (Since many IDE does not let you use the latest jdk...?)
thanks
Unni

I'm wondering what this has to do with which IDE you're using?
