Example

In the code below, two Double values are defined. Both are the results of division by zero. The results are checked for infinity using the Double.isInfinite() method.

import java.lang.Double;
public class Main {
public static void main(String args[])
{
Double d1 = 1.0 / 0.0;
Double d2 = 0/0.0;
System.out.println(d1 + " - " + Double.isInfinite(d1));
System.out.println(d2 + " - " + Double.isInfinite(d2));
}
}
