Java Float byteValue() method

The byteValue() of Java Float class returns the value of this Float as a byte by narrowing the primitive values or in simple words by casting to a byte.

Syntax:

Parameters:

Return Value:

This method returns the bytevalue which has been converted from the float value of this object.

Example 1

import java.lang.Float;


public class FloatbyteValueExample1{

    public static void main(String[] args) {
        
    
        Float f1= new Float("10");
   Float f2=new Float("50.44");
     float c= f1+f2;
    System.out.println("Sum = "+c);


    //method is returning the value of float as byte
    byte b1=f1.byteValue();
    byte b2=f2.byteValue();

    int d= b1+b2;
    System.out.println("Sum = " +d);
}
}

Test it Now

Output:

Sum = 60.44
Sum = 60

Example 2

public class FloatbyteValueExample2{

    public static void main(String[] args) {



     // by typecasting float to byte
        float f1= 10.5f ;
        byte b1=(byte)f1;
        System.out.println("float value = "+f1);
        System.out.println("Converted byte value by type casting = "+b1);

        //by byteValue method
        Float f2= new Float(10.5);
        System.out.println("Converted byte value by byteValue method=" +f2.byteValue());



     }
}

Test it Now

Output:

float value = 10.5
Converted byte value by type casting = 10
Converted byte value by byteValue method=10

Example 3

public class FloatbyteValueExample3{

    public static void main(String[] args) {

        float f1= 10.5f;
        System.out.println("float value = "+f1);
        System.out.println("Converted byte value by type casting = "+f1.byteValue());

     }
}

Test it Now

Output:

Error:(16, 72) java: float cannot be dereferenced
-

Float is a primitive data type; its object cannot be used to call the Float class method. If you do this, you will get an error like above example.
