Change text

[Johanis]

I am writing a table tennis score program and every time two points (or the desired amount) have been played I want an arrow to face the opposite way that it faceing... This is the code so far. Please help!

private void Score()
      {
         String redd = scoreblue.getText();
         String bluee = scorered.getText();
         int red = Integer.parseInt(redd);
         int blue = Integer.parseInt(bluee);
        int rb = red+blue;
        int rbdiv = rb/2;
        if((rb) == (rbdiv == Integer))
         {
         pyl.setText("-->");
         }
      }

a) Write a method that change/turns the arrow
b) if(points % desiredAmount == 0) { invoke your method } ....

Thank you!! How do I write a method that changes/turns the arrow?

Do you have no idea?
pyl.setText(pyl.getText().equals("-->")?"<--":"-->");

But in my opinion, it would be better if you would use more OOP. Create classes for the player, scoreboard and so on maybe...

I tried

if(rb%2 == 0)
         {
           
           if(rigting == ("-->")
           {
           pyl.setText("<--");
           }
            pyl.setText("-->");
           }
           }

hahaha but thanks!!

"..." = strings = objects = you have to compare them by method --> equals!

Java: ==, .equals(), compareTo(), and compare()
