     JOptionPane.showMessageDialog(null,"You're a junior.");

  }//end if

  else if(credit >= 30)

     JOptionPane.showMessageDialog(null,"You're a sophomore.");

     JOptionPane.showMessageDialog(null,"You're a freshment.");

Answer 1

Use the if-else statements to generate the String to show, then use a single line to call showMessageDialog() using the String.
