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.
