5.6. Running Until Encountering a Breakpoint


You don’t want to single-step through many lines of code while debugging. Rather, you want to step through breakpoints only.


While paused at a breakpoint, click the Resume button in the Debug view or select Run Resume. Execution continues until the next breakpoint is encountered.


If you don’t want to keep single-stepping through your code, you have other options. For example, you can simply let your code execute until it reaches a breakpoint. To do that, just click the Resume button in the Debug view (the arrow button to the right of the word Debug in the Debug view), or select Run Resume.

In the previous recipe, we stopped at a breakpoint and then single-stepped to the next line of executable code. Clicking Resume resumes program execution until the breakpoint is encountered for a second time, and the index loopIndex will hold a value of 2, as shown in Figure 5-13.

Clicking Resume again takes us to the next iteration, where loopIndex holds 1. Clicking loopIndex one more time makes the code execute until the program terminates, which is unexpected because we’re waiting for loopIndex to equal 0.

Getting an unexpected result is an indication you’ve found your bug; the problem is in the line in which we’ve set up the for loop incorrectly:

public class DebugClass { public static void ...
