How to return swap value

#1

it is not accepting another RETURN
my code:
public static void main(String[] args) {

	int one = 10;
	int two = 20;
	System.out.println(one + " " + two);
	int res = swap(one, two);
	System.out.println(res);
}

public static int swap(int one, int two) {
	int temp = one;
	one = two;
	two = temp;

	return one;
	//return two;
}
#2

you can return only one value from a function…so if you want to return a group of values from a function return an object of class from the function…
class Pair{
int one;
int two;
}
public static Pair fnc(){
//your function
}
return an object of pair class from the function…

i have not reached to that level in the course
i have done till arrays
can you tell me how to do this problem other way

#4

if you want that your changes should persist in your main function make variables one and two as global…change the return type of you swap function from int to void and also your swap functions will not take any arg…swap function will not return any value instead it will just swap those two elements…as global variables are made in heap changes will persist
you can refer to this code:
