1.

What is the output of the following program?

public class Main {
public static void main(String[] args) {
int i = 0;
while (i < 10) {
i++;
if (i % 2 == 0) {
continue;
}
System.out.print(i + " ");
}
}
}

2 4 6 8 10

1 3 5 7 9

2 4 6 8

1 3 5 7

2.		Which control flow statement is used to skip the remaining statements in the current iteration of a loop and move on to the next iteration?

continue

break

return

skip

3.		Which of the following is not a valid loop control statement in Java?

continue

break

return

goto

4.		Which of the following statements is true about nested loops in Java?

Nested loops can only be used with for loops, not with while or do-while loops.

A break statement inside a nested loop terminates only the innermost loop.

A continue statement inside a nested loop skips only the innermost loop.

Nested loops are never used in real-world programming.

5.		What is the purpose of the labeled statement in Java?

To define a new variable in the code.

To provide a descriptive name for a loop or if statement.

To mark a specific point in the code that can be jumped to using the goto statement.
