Thread: Beginner Java Course, Stuck on my First Assignment. Help Needed.

Welcome to the forum! Please read this topic to learn how to post code correctly and other useful info for new members.

Start with what you know and code/test that. Come back with that code and ask for help with the next part, if you still need it. Be sure to post your code correctly per the above link.

Try to build logic and if it do not workout post the algorithm here we will try to help you.Building logic is the very important part of programming.so try yourself.

first of all...get the two values that is to swap from the user with the help of scanner object.... then you can swap the values by taking a third temporary variable that stores the value of the first two variables temporarily, one by one, for sometime.

Ok. I hope this does it.

public class Swapping   {
   int x = 1;
   int y = 4;
 
    public static void main(String args[])  {
     If(x)
      {
         System.in.println(x);
         }
          System.in.println(y);
 
           switch(x)
            }
            case 1;
            int y = x;
            System.out.println("case 1);
            break;
            case 2;
            int x = y;
            System.out.println("case 2);
            break;
            }
    }
}
