Line number from JPDA/JDI JVM

[neogguy]

Does anyone know how to get which lines in a peice of code has been
executed.

Lets say I have a programme of 20 lines and only line 10 to 15 have
been executed, is there anyway of finding out those lines from the JVM
with JPDA/JDI or something.

Thanks

There is. You'll need jdk 1.4, which supports profiling, and a
profiling tool. Google around for java profiling tools. There are
tons of them.

but I'm trying to write a programme that will do that.

lets say I have a programme like this

1 int x=2;
2 int y=3;
3 int z=0;
4 z=x+y;
5 for(int m=0; m<0; m++)
6 {do something;
7 }

I want to write a programme that will give an output of
1
2
3
4

as line 5 to 7 will never run, but 1 to 4 did.

Thanks
