Answer: option a

Explanation:

The code initializes the variable i to 0, then enters a do-while loop that runs at least once and continues to run as long as i is less than 5. The loop body prints the value of i and increments it by 1. This loop will run 5 times, printing the numbers 0 through 4.

17.		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 + " "); } } }

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 + " ");
}
}
}

Answer: option b

Explanation:

The continue statement skips the remaining statements in the current iteration of the loop if the condition is true. In this code, the continue statement is executed if i % 2 == 0, which skips even numbers.
