Debug Java Loops Faster: Use Conditional Breakpoints in IntelliJ IDEA

Today DD shares a handy debugging tip for IntelliJ IDEA.

When a loop may fail at a specific iteration (e.g., the 27th), instead of repeatedly stepping through, you can set a conditional breakpoint.

for(int i = 0; i < 100; i++) {
    // business logic
    System.out.println(i);
}

Right‑click the red breakpoint dot, choose the Condition field, and enter an expression such as i == 27. The program will pause automatically when the loop reaches that iteration.

This avoids manually clicking the green “resume” arrow many times and works in many complex debugging scenarios.
