Java Float isInfinite() Method

The isInfinite() method of Java Float class returns a Boolean value for the specified float object or for ‘v’. This method returns true if the argument passed is infinitely large in magnitude and returns false for finite floating-point arguments.

The isInfinite() method is vice – versa of ‘isFinite()’ method.

Syntax:

Parameters:

1.The parameter passed is ‘v’ which is of float type.
NA

Return Value:

This method returns a Boolean value for this float object.

Returns true, if the argument passed is positive or negative infinity.
Returns false, if the arguments passed is Nan or finite floating-point numbers.

Example 1

  public class FloatIsInfiniteExample1 {      public static void main(String[] args) {          float f1 = 578648.67f;          Float f2 = new Float(f1/0);             //isInfinite will return true for infinity values          System.out.println(f2+” value for isInfinite() method is : ” +Float.isInfinite(f2));             //isFinite method will return false as f1/0 is infinity          System.out.println(f2+” value for isFinite() method is   : “+Float.isFinite(f2));           }      }  

Test it Now

Output:

Infinity value for isInfinite() method is : true  Infinity value for isFinite() method is   : false

Example 2

  public class FloatIsInfiniteExample2 {      public static void main(String[] args) {          // will return false          Float f1 = new Float(0X7f800000);          System.out.println(“1. “+f1+” value = ” + Float.isInfinite(f1));          //will return false          Float f2 = new Float(76E-43);          System.out.println(“2. “+f2+” value = ” + Float.isInfinite(f2));          //will return false for NaN          Float f3 = new Float(0.0/0.0);          System.out.println(“3. “+f3+” value = “+ Float.isInfinite(f3));          //will return true for negative infinity          Float f4 = new Float(-3723.93/0.0);          System.out.println(“4. “+f4+” value = “+ Float.isInfinite(f4));        }  }  

Test it Now

Output:

1. 2.13909504E9 value = false  2. 7.6E-42 value = false  3. NaN value = false  4. -Infinity value = true

Example 3

  public class FloatIsInfiniteExample3 {      public static void main(String[] args) {          Float f1 = new Float(76434763746.82468746746874827);          //static isInfinite() method          boolean b1=Float.isInfinite(f1);          System.out.println(“1. “+f1+” value = “+b1);          float f2 = 27.827f;          //It also be called inside println function          System.out.println(“2. “+f2+” value = “+Float.isInfinite(f2));            float f3= Float.POSITIVE_INFINITY;          System.out.println(“3. “+f3+ ” value = ” +Float.isInfinite(f3));            float f4= Float.NEGATIVE_INFINITY;          System.out.println(“4. “+f4+ ” value = ” +Float.isInfinite(f4));        //returns false for NaN value          float f5=Float.NaN;          System.out.println(“5. “+f5+ ” value = ” +Float.isInfinite(f5));          }  }  

Test it Now

Output:

1. 7.643476E10 value = false  2. 27.827 value = false  3. Infinity value = true  4. -Infinity value = true  5. NaN value = false

Example 4

  public class FloatIsInfiniteExample4 {      public static void main(String[] args) {          float f1 = Float.POSITIVE_INFINITY;          //calling method with float object f1          boolean f2 = f1.isInfinite();          System.out.println(f2);          }  }  

Test it Now

Output:

Error:(7, 24) java: float cannot be dereferenced

Here, float is primitive data type. Its object can’t be used to call Float class methods. If done, so it will give the above described error.
