int h = 2019;
gar(x,m,h);
System.out.println(m,x,h);
}

Answer 1

In java, it won't possible to return more than one element. So you have use a datastructure or array to return multiple values...
Or for simple codes, form to a string and on return extract back again..

Answer 2

method 1. use a global variable to change the values easily.

method 2. yes it's actually possible to return more than one values with arrays.

import java.util.Arrays;
public class Program
{
public static int gar(int x,int m,int h){
x *= 2 ;
return new int[] {x,m,h};
}
public static void main(String[] args) {
int x =5, m = 12, h = 2019;
int[] arr = gar(x,m,h);
System.out.println(Arrays.toString(arr));
}
}
