An Example of Using Java Operators

Demo Code

public class Main {
  public static void main ( String[] args ) {
    int num = 1110;
    double realNum = 25.1115F;
    double veryBigNum = 215.8 / 0.0;  
    double garbage = 0.0 / 0.0; 
    boolean test = true;
    /* ww w  . j  a va2s .c  om*/
    System.out.println ("num = " + num);
    System.out.println ("realNum = " + realNum);
    System.out.println ("veryBigNum = " + veryBigNum);
    System.out.println ("garbage = " + garbage);
    System.out.println ("test = " + test);
    System.out.println ("Maximum int = " + Integer.MAX_VALUE);
    System.out.println ("Maximum double = " + Double.MAX_VALUE);
    System.out.println ("12.5 + 100 = " + (12.5 + 100));
    System.out.println ("12.5 - 100 = " + (12.5 - 100));
    System.out.println ("12.5 * 100 = " + (12.5 * 100));
    System.out.println ("12.5 / 100 = " + (12.5 / 100));
    System.out.println ("12.5 % 100 = " + (12.5 % 100));
    System.out.println ("\"abc\" + \"xyz\" = " + "\"" + ("abc" + "xyz") + "\"");
    
  }
}
