Java is Pass-By-Value
Primitive types swap method will never work because Java is strictly Pass-By-Value. If you want to swap two arguments, use array or object to send reference as a value. Example I primitive types are never changed class Main { //primitive type doesn't swap public static void swap(int i, int j) { int temp = i; i = j; j = temp; } public static void main(String[] args) { int i = 10; int j = 20; swap..
