Byte class floatValue() method

  • floatValue() method is available in java.lang package.
  • floatValue() method is used to return the value denoted by this Byte object converted to type float (by casting).
  • floatValue() 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.
  • floatValue() method does not throw an exception at the time of conversion from Byte to float.


    public float floatValue();


  • It does not accept any parameter.

Return value:

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


// Java program to demonstrate the example 
// of floatValue() method of Byte class

public class FloatValueOfByteClass {
    public static void main(String[] args) {
        // Variables initialization
        byte b1 = 30;
        byte b2 = 40;;

        // It returns an byte value denoted by this Byte ob1 object
        // and converted to a float by calling ob1.floatValue()
        Byte ob1 = new Byte(b1);

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

        // It returns a byte value denoted by this Byte ob2 object
        // and converted to a float by calling ob2.floatValue()
        Byte ob2 = new Byte(b2);

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


ob1.floatValue(): 30.0
ob2.floatValue(): 40.0
