Problem in eclipse IDE Galileo

[kumarjit banerjee]

Hi,

I am facing a problem in eclipse IDE.

package kumar;

public class Demo3{

public static void main(String args[]){
	
	System.out.println("My ");
	System.out.println("name ");
	System.out.println("is ");
	System.out.println("Kumarjit");
	System.out.println(".");
	try{
	throw new NullPointerException();
	}catch(Exception e){
		e.printStackTrace();
	}	
}	
}

In the above code, The exception is printed at different locations when run successively. The ideal output, which I got from running in command prompt, should be

My 
name 
is 
Kumarjit
.
java.lang.NullPointerException
	at kumar.Demo3.main(Demo3.java:13)

But when run successively I got the output as above and also different output such as

java.lang.NullPointerException
	at kumar.Demo3.main(Demo3.java:13)
My 
name 
is 
Kumarjit
.

That is because e.printStackTrace(); prints to a different output stream: System.err instead of System.out.

The System.out and System.err streams by default do both write their output to the console, but they are not synchronized with regard to each other. Therefore, the order of messages as they appear on the console via those two streams is not predictable.

Eclipse is notorious for mixing System.out and System.err in unpredictable ways.
