import java.lang.*;

public class FloatDemo {

   public static void main(String[] args) {

     Float f1 = new Float(1.0/0.0);
     Float f2 = new Float(0.0/0.0);
  
     // returns true if positive or negative infinity, else false
     System.out.println(f1 + " = " + f1.isInfinite(f1));

     System.out.println(f2 + " = " + f2.isInfinite(f2));
