java.lang.Byte longValue()
Description
The longValue() method of Byte class returns the value of this Byte as a long after a widening primitive conversion.
Important Notes:
- The method
longValue()
is specified by longValue() in class Number
Method Syntax
public long longValue()
Method Argument
Data Type | Parameter | Description |
---|---|---|
N/A | N/A | N/A |
Method Returns
The longValue() method of Byte class returns the numeric value represented by this object after conversion to type long.
Compatibility
Requires Java 1.1 and up
Java Byte longValue() Example
Below is a simple java example on the usage of longValue() method of Byte class.
package com.javatutorialhq.java.examples; import java.util.Scanner; /* * This example source code demonstrates the use of * longValue() method of Byte class. */ public class ByteLongValueExample { public static void main(String[] args) { /* * Editor's Note * Be extra careful in using this method * as it uses widening concept */ // ask for user input System.out.print("Enter a number:"); // read the user input Scanner s = new Scanner(System.in); String value = s.nextLine(); s.close(); Byte byteValue = new Byte(value); // convert byteValue into long long result = byteValue.longValue(); System.out.println("long value is "+result); } }
Basically on the above example, we have asked the user to enter a number on the console. Internally the input value is assign to a Byte object. We then use the longValue() method to convert it into type long. It doesn’t do much however it shows the basic behaviour of this method.
