The best practice for an OOP approach is to return an Object. An object that contains all the values you want.
Example:
class Main {
public static void main(String[] args) {
MyResponse response = requestResponse();
System.out.println( response.toString() );
}
private static MyResponse requestResponse() {
return new MyResponse( "this is first arg", "this is second arg" );
}
}
class MyResponse {
private String x, y;
public MyResponse( String x, String y ) {
this.x = x;
this.y = y;
}
@Override
public String toString() {
return "x: " + x + "\t y: " + y;
}
}
If you want an even more scalable approach then you have to use JSON responses. (let me know if you want an example with JSON too)
