Example

The following example shows the usage of java.lang.Float.isInfinite() method.

package com.tutorialspoint;

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));
   }
}   

Let us compile and run the above program, this will produce the following result −
