Output of loop with continue skipping even numbers

What is the output of this Java code snippet?

Java

for (int i = 1; i <= 5; i++) {
    if (i % 2 == 0) {
        continue;
    }
    System.out.print(i + " ");
}

A 1 3 5

B 2 4

C 1 2 3 4 5

D 1 3 4 5

💡 Hint

The continue statement skips the current iteration when the number is even.

The loop prints numbers from 1 to 5. When the number is even, continue skips printing it. So only odd numbers 1, 3, and 5 are printed.

Effect of continue in nested loops

What will be printed by this Java code?

Java

for (int i = 1; i <= 3; i++) {
    for (int j = 1; j <= 3; j++) {
        if (j == 2) {
            continue;
        }
        System.out.print(i + "-" + j + " ");
    }
}

A 1-1 1-3 2-1 2-3 3-1 3-3

B 1-1 1-2 1-3 2-1 2-2 2-3 3-1 3-2 3-3

C 1-2 2-2 3-2

D 1-1 2-1 3-1

💡 Hint

The continue skips printing when j equals 2, but the outer loop continues.

For each i, the inner loop prints j except when j is 2. So j=1 and j=3 print for each i.

Continue statement effect on while loop

What is the output of this Java code?

Java

int i = 0;
while (i < 5) {
    i++;
    if (i == 3) {
        continue;
    }
    System.out.print(i + " ");
}

A 2 3 4 5

B 1 2 3 4 5

C 1 2

D 1 2 4 5

💡 Hint

The continue skips printing when i equals 3, but i is incremented before the check.

i increments from 0 to 5. When i is 3, continue skips printing. So output excludes 3.

Continue inside for loop with multiple conditions

What will this Java code print?

Java

for (int i = 1; i <= 6; i++) {
    if (i % 2 == 0 || i % 3 == 0) {
        continue;
    }
    System.out.print(i + " ");
}

A 1 5 6

B 1 5

C 1 2 3 4 5 6

D 1 4 5

💡 Hint

Numbers divisible by 2 or 3 are skipped.

Numbers 2,3,4,6 are skipped because 2 and 4 are divisible by 2, 3 and 6 by 3. Only 1 and 5 print.

Behavior of continue in labeled loops

Consider this Java code with labeled loops. What is the output?

Java

outer:
for (int i = 1; i <= 3; i++) {
    inner:
    for (int j = 1; j <= 3; j++) {
        if (i == j) {
            continue outer;
        }
        System.out.print(i + "-" + j + " ");
    }
}

A 1-2 2-3 3-1

B 1-2 1-3 2-1 2-3 3-1 3-2

C 2-1 3-1 3-2

D 1-2 1-3 2-1 3-1 3-2

💡 Hint

The continue outer skips the rest of the inner loop and moves to the next iteration of the outer loop when i == j.

When i equals j, continue outer skips the rest of the inner loop and moves to the next iteration of the outer loop. For i=1, j=1 triggers continue outer, skipping the entire inner loop, so nothing prints for i=1. For i=2, j=1 prints 2-1, then j=2 triggers continue outer. For i=3, j=1 and j=2 print before j=3 triggers continue outer.
