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

    I am taking my first Java course and I am stuck on my assignment which is the following:

    Write a java program that prompts the user to input two integer values, swap the values of two variables (don’t just display them in opposite locations), and then display the swapped values back to the user.

    I have an idea of what it is supposed to look like:

    Please enter two values:
    Value #1 = 1
    Value #2 = 4
    Swapping…
    Value #1 = 4
    Value #2 = 1

    I understand that i have to use the Scanner object to get the user inputs and I understand how to prompt the user to insert values. What I really need help on is the "swapping" of the values and displaying them back to the user.

    Any help is really appreciated. Thank You.

    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;
                }
        }
    }

    Your post is over 3 years too late.

    In the future please don't post full solutions for OPs questions without any comments to explain what the code is doing

    and also make sure the code will compile, execute and produce the correct results before posting solutions.
    If you don't understand my answer, don't ignore it, ask a question.
