Java - Byte floatValue() method



Description

The Java Byte floatValue() returns the value of this Byte as a float.

Declaration

Following is the declaration for java.lang.Byte.floatValue() method

public float floatValue()

Specified by

floatValue in class Number

Parameters

NA

Return Value

This method returns the numeric value represented by this object after conversion to type float.

Exception

NA

Example 1

The following example shows the usage of Byte floatValue() method with Byte object created using new operator. We're creating a Byte variable and assigned it an Byte object created using new operator. Then a float variable is created and assigned a float value using floatValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = new Byte("100");

      // create a float primitive d
      float d;

      // assign primitive value of b to d
      d = b.floatValue();

      String str = "Primitive float value of Byte object " + b + " is " + d;

      // print d value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive float value of Byte object 100 is 100.0

Example 2

The following example shows the usage of Byte floatValue() method with Byte object created using valueOf(String) method. We're creating a Byte variable and assigned it an Byte object created using valueOf(String) method. Then a float variable is created and assigned a float value using floatValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = Byte.valueOf("100");

      // create a float primitive d
      float d;

      // assign primitive value of b to d
      d = b.floatValue();

      String str = "Primitive float value of Byte object " + b + " is " + d;

      // print d value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive float value of Byte object 100 is 100.0

Example 3

The following example shows the usage of Byte floatValue() method with Byte object created using valueOf(byte) method. We're creating a Byte variable and assigned it an Byte object created using valueOf(byte) method. Then a float variable is created and assigned a float value using floatValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = Byte.valueOf((byte) 100);

      // create a float primitive d
      float d;

      // assign primitive value of b to d
      d = b.floatValue();

      String str = "Primitive byte value of Byte object " + b + " is " + d;

      // print d value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive byte value of Byte object 100 is 100.0
