Java - Float Class longValue() Method

Float class longValue() method: Here, we are going to learn about the longValue() method of Float class with its syntax and example. By Preeti Jain Last updated : March 21, 2024

Float class longValue() method

longValue() method is available in java.lang package.
longValue() method is used to return the value denoted by this Float object converted to type long (by casting).
longValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
longValue() method does not throw an exception at the time of conversion from float to long.

Syntax

public long longValue();

Parameters

It does not accept any parameter.

Return Value

The return type of this method is long, it returns a converted (from type float to long) value represented by this Float object.

Example

// Java program to demonstrate the example 
// of longValue() method of Float class

public class LongValueOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float f1 = 18.20f;
        float f2 = 19.20f;

        // It returns float value denoted by this Float ob1 object
        // and converted to a long by calling ob1.longValue()
        Float ob1 = new Float(f1);

        // Display ob1 result
        System.out.println("ob1.longValue(): " + ob1.longValue());

        // It returns float value denoted by this Float ob2 object
        // and converted to a long by calling ob2.longValue()
        Float ob2 = new Float(f2);

        // Display ob2 result
        System.out.println("ob2.longValue(): " + ob2.longValue());
    }
}

Output

ob1.longValue(): 18
ob2.longValue(): 19
