How to pause a java program in eclipse by code

Question

Is there any java code, which can make a java program pause in eclipse debugger, just like breakpoint? Then I can check the information of debugger, like values, stack. Someone may misunderstand my question. I often write code for debugging like this

if(some_condition){
    print_log();
    abort();
}

In Visual Studio, I write abort() function. When I run a program in debug mode, abort() function can make the program pause and I can check the debugger.Is there some function in java like abort() in C++?

So debugger is already there with break points.Why u require this ? — Deepak, Aug 21 '14 at 09:49
Why don't you just place a breakpoint where you need it to stop? — omerio, Aug 21 '14 at 09:49
My guess is he wants a conditional breakpoint - so the program itself can decide to pause. Not unreasonable — The Archetypal Paul, Aug 21 '14 at 10:26

I think you'll want to use conditional breakpoints. I guess you don't want to define a beakpoint which will block your program each it passes on a given line, but only when specific condition occur.

So define a breakpoint, and add a boolean condition to it. You may for example define some variable like :

boolean must_break = false;

Then later on

if (some_condition) { must_break = true; }

Just set you breakpoint on any line with

must_break=false

That way, you control when you want to break you program's execution, and the must_break condition is reset for the next time.

This is a method. But I don't know whether configuring the condition breakpoint is as convenient as abort() function in C++. I have edited my question. Thanks for your answer! — umbrella, Aug 22 '14 at 15:10
