Continue statement in Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the continue statement do in a loop?

It skips the current iteration and immediately jumps to the next iteration of the loop.

beginner

In which types of loops can you use the continue statement in Java?

You can use continue in for, while, and do-while loops.

What happens if continue is used inside a nested loop?

It only affects the innermost loop where it is used, skipping to the next iteration of that loop.

Example: What will be printed by this code?<br>

for (int i = 1; i <= 5; i++) {<br>  if (i == 3) continue;<br>  System.out.print(i + " ");<br>}

The output will be: 1 2 4 5 <br>Because when i is 3, continue skips printing it.

Why might you use continue instead of if-else inside a loop?

Using continue can make code cleaner by skipping unwanted cases early, avoiding nested if-else blocks.

What does the continue statement do inside a loop?

A Restarts the entire program

B Exits the loop completely

C Pauses the loop until a condition is met

D Skips the rest of the current iteration and moves to the next iteration

The continue statement skips the rest of the current loop iteration and moves to the next one.

In a for loop, what happens after continue is executed?

A The loop variable is updated and the next iteration starts

B The loop stops immediately

C The program crashes

D The loop variable resets to zero

After continue, the loop updates the variable and starts the next iteration.

Can continue be used in a while loop?

A Only in <code>do-while</code> loops

B No, it only works in <code>for</code> loops

C Yes, it skips to the next iteration

D Only inside <code>switch</code> statements

continue works in all loop types including while.

What will this code print?<br>

for (int i = 0; i < 4; i++) {<br>  if (i == 2) continue;<br>  System.out.print(i);<br>}

A 0123

B 013

C 123

D 023

When i is 2, continue skips printing it, so output is 0,1,3.

If continue is inside nested loops, which loop does it affect?

A Only the innermost loop where it appears

B All loops at once

C Only the outermost loop

D It exits all loops

continue affects only the loop it is directly inside.

Explain how the continue statement changes the flow inside a loop.

Think about what happens when you want to skip some steps but keep looping.

Describe a situation where using continue makes your code simpler than using nested if-else.

Imagine checking many conditions but only want to act on some.
