debug - breakpoint -- only stop when a variable is a certain value?

[Ben David]

I want to debug a program that runs through a lot of loops within loops. I want to set a break point, but the iteration I want to look at is hundreds of iterations in.

Is there a way to set a conditional breakpoint? So that it will only stop at the breakpoint when a variable I specify has a value that I specify?

What about a conditional print?

if (x == 3 && y ==4) System.out.printf("Line 123: a = %f, b = %f%n", a, b); //test

maybe this helps

FAQ How do I set a conditional breakpoint?

netbeans has something like this

Hi Ben,

As you can see, the answer to 'can I' is "yes" -- but the answer to 'how can I' depends entirely on what debugger (i.e., what development tools) you're using, which you neglected to mention. Let us know and somebody can probably tell you exactly what to do.

oops!! -- my bad!! I was totally meant to say I was using netbeans, but failed to get that into the post!

Anyway Ernesto Chicas comment helped me out. Dont know why i didnt try right clicking the breakpoint after setting it. I can then click "properties" and have a box where I can set the condition.


Thanks all!

This sounds like a NetBeans-related question which would sit better on our IDEs forum. Moving.
