↩Back to Check Condition

The loop starts and checks its condition. If true, it runs the body. If a break is triggered inside, it exits the loop immediately. Otherwise, it continues to the next iteration until the condition is false.

Execution Sample

Java

for (int i = 0; i < 5; i++) {
    if (i == 3) {
        break;
    }
    System.out.println(i);
}

This loop prints numbers from 0 to 4 but stops early when i equals 3.

Execution Table

Iteration	i value	Condition (i < 5)	Break Condition (i == 3)	Action	Output
1	0	true	false	Print 0	0
2	1	true	false	Print 1	1
3	2	true	false	Print 2	2
4	3	true	true	Break loop
-	-	false	-	Exit loop	-

💡 Loop exits at iteration 4 because break condition i == 3 is true.

Key Moments - 2 Insights

Why does the loop stop printing when i reaches 3?

Because at iteration 4, the break condition (i == 3) becomes true, triggering the break statement which immediately exits the loop (see execution_table row 4).

Does the loop condition (i < 5) stop the loop in this example?

No, the loop condition is still true when i is 3, but the break statement stops the loop early before the next iteration (see execution_table rows 3 and 4).

Visual Quiz - 3 Questions

Look at the execution table, what is the value of i when the break statement is triggered?

A 2

B 4

C 3

D 5

💡 Hint

Check the 'Break Condition' and 'i value' columns at iteration 4 in the execution_table.

At which iteration does the loop stop executing the print statement?

A Iteration 4

B Iteration 3

C Iteration 5

D Iteration 2

💡 Hint

Look at the 'Action' and 'Output' columns in the execution_table to see when printing stops.

If the break statement was removed, what would be the last value printed?

A 3

B 4

C 5

D 2

💡 Hint

Without break, the loop runs until i < 5 is false, so check the maximum i value before condition fails.

Concept Snapshot

Break statement in Java:
- Used inside loops to exit immediately.
- Syntax: break;
- Stops loop even if condition is still true.
- Useful to stop early based on a condition.
- After break, code continues after the loop.

Full Transcript

This example shows a for loop in Java that counts from 0 to 4. Inside the loop, there is a check if the variable i equals 3. When this happens, the break statement runs, which immediately stops the loop. The loop prints the values 0, 1, and 2, then stops before printing 3 because of the break. The loop condition i < 5 remains true at that point, but break overrides it to exit early. This helps stop loops when a certain condition is met without waiting for the loop to finish all iterations.
