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.


    public long longValue();


  • 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.


// 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());


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