Java Program to check if a Float is Infinite or Not a Number(NAN)
To check if a Float is isInfinite, use the isInfinite() method and to check for NAN, use the isNaN() method.
Example
public class Demo {
public static void main(String[] args) {
float value1 = (float) 1 / 0;
boolean res1 = Float.isInfinite(value1);
System.out.println("Checking for isInfinite? = "+res1);
float value2 = (float) Math.sqrt(9);
boolean res2 = Float.isNaN(value2);
System.out.println("Checking for isNan? = "+res2);
}
}Output
Checking for isInfinite? = true Checking for isNan? = false
