Break & Continue Statements

In Plain English

`break` and `continue` give you fine-grained control over loop execution. `break` terminates the entire loop immediately, while `continue` aborts only the current iteration and jumps directly to the next cycle.

The Mental Model

"Think of reading a playlist: `break` means stopping the music player completely and walking away. `continue` means pressing the "Skip Track" button to start the next song immediately."

Deep Dive: How It Works

`break`: Immediately halts the enclosing loop and transfers control to the line following the loop.

`continue`: Skips whatever remaining lines are in the current iteration and advances to the loop update step.

Labeled breaks: Java allows labeling outer loops (e.g. `outer: for(...)`) to break out of nested loops directly.

Syntax Blueprint

for (int i = 1; i <= 10; i++) {
    if (i == 3) continue; // skip 3
    if (i == 7) break;    // stop at 7
    System.out.println(i);
}

Use continue to skip unwanted items and break for early termination on matches.

Core Rules to Remember

Break Exits Loop: Stops all further iterations of the loop.

Continue Skips Cycle: Jumps directly to the next iteration step.

Works Across All Loops: Usable in while, do-while, and for loops.

Common Beginner Traps & How to Fix Them

Mistake:Putting code after break or continue in the same block

Why it happens: Java compiler detects this as "unreachable statement" and will reject the build.

How to fix: Ensure break and continue are the last statements executed in that branch.

Pro Tip: Use break when searching through data: once you find the target item, break immediately to save processing time.

How it works: 1, 3, 5 are skipped with continue. 2, 4, 6 print. When i becomes 8, break terminates the loop.
