Float class byteValue() method

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

Syntax:

    public byte byteValue();

Parameter(s):

  • It does not accept any parameter.

Return value:

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

Example:

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

public class ByteValueOfFloatClass {
    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 byte by calling ob1.byteValue()
        Float ob1 = new Float(f1);

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

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

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

Output

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