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. 1.The parameter passed is 'v' which is of float type.
2. 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

Output:

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

Example 2

Output:

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

Example 3

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

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.
