The longValue() method of Byte class is a built in method in Java which is used to return the value of this Byte object as long.
Syntax
ByteObject.longValue()
Return Value: It return the value of ByteObject as long.
Below is the implementation of longValue() method in Java:
Example 1:
// Java code to demonstrate// Byte longValue() method  class GFG {    public static void main(String[] args)    {          // byte value        byte a = 17;          // wrapping the byte value        // in the wrapper class Byte        Byte b = new Byte(a);          // longValue of the Byte Object        long output = b.longValue();          // printing the output        System.out.println("Long value of "                           + b + " is : " + output);    }} |
Output:
Long value of 17 is : 17
Example 2:
// Java code to demonstrate// Byte longValue() method  class GFG {    public static void main(String[] args)    {          String value = "17";          // wrapping the byte value        // in the wrapper class Byte        Byte b = new Byte(value);          // longValue of the Byte Object        long output = b.longValue();          // printing the output        System.out.println("Long value of "                           + b + " is : " + output);    }} |
Output:
Long value of 17 is : 17
