int i=1;
while(i<=10)
{
    System.out.println(i);
    i++;
}
Q2. What will be output of this program.
int x=4,y,z;
y=--x;
z=x--;
System.out.println(x);
System.out.println(y);
System.out.println(z);
output:-
2

3

Q3. What will be output of this program.
int x=4, y=3,z;
z = x-- - y;
System.out.println(x);
System.out.println(y);
System.out.println(z);
output:-
3

Q4. What will be output of this program.
package com.company;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
       double i =1.1;
       while (i==1.1)
       {
           System.out.println(i);
           i=i-0.1;
       }
