Output even number between 1 and 50 without using any operator and extra variable.

Question

first question.

Answer 1

import java.util.concurrent.ThreadLocalRandom;

public class Program
{
public static void main(String[] args) {
// get a random number from 0 to 25
int x = ThreadLocalRandom.current().nextInt(0, 26);
// use bitwise multiplication x*2
System.out.println(x<<1);
}
}

if you want to get rid of the variable just move the line where x is and surround it in parentheses.

(ThreadLocalRandom.current().nextInt(0, 26))<<1

Answer 2

please use any operator at all (even bitwise multiplication)
