Float longValue() in Java with Examples

The java.lang.Float.longValue() method in Float Class is a built in method in Java that returns the value specified by the calling object as long after type casting.

Syntax:

public long longValue()

Parameters: It takes no parameters.

Return type: It returns an long value i.e. the type casted value of the FloatObject.

Below is the implementation of the above method.

    public static void main(String[] args)
    {
  
        // creating a Float object
        Float d = new Float(1022);
  
        // longValue() method of Float class
        // typecast the value
        long output = d.longValue();
  
        // printing the output
        System.out.println(output);
    }
