public class operateExam {
  public static void main(String args[]) {
    int myInt = 9 / 2;
    double myD = 9 / 2.0;
    byte myB1 = 7, myB2 = 8;
    long myLong = 50L;
    long myR1 = myLong / myInt;
    int myR2 = myB1 * myB2;
    float myFloat = 6.2f;
    float myR3 = myFloat - myR2;
    double myDR = myD % myInt;
    System.out.println("myInt=" + myInt);
    System.out.println("myD=" + myD);
    System.out.println("myR1=" + myR1);
    System.out.println("myR2=" + myR2);
