Java - Byte Class decode() Method

Short class decode() method: Here, we are going to learn about the decode() method of Short class with its syntax and example. By Preeti Jain Last updated : March 18, 2024

Short class decode() method

decode() method is available in java.lang package.
decode() method is used to decode the given String value into a Byte value.
decode() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
decode() method may throw a NumberFormatException at the time of decoding a String to a Byte.
NumberFormatException: In this exception, if the given string parameter does not have a parsable byte.

Syntax

public static Byte decode(String str);

Parameters

String str – represents the String to decode.

Return Value

The return type of this method is Byte, it returns the Byte holding a byte value represented by the argument of String type.

Example

// Java program to demonstrate the example 
// of decode(String str) method of Byte class

public class DecodeOfByteClass {
    public static void main(String[] args) {
        // Variables initialization
        byte by = 100;
        String str = "20";

        // Byte object initialized with "byte" value
        Byte value1 = new Byte(by);

        // Display value1 result
        System.out.println("value1:" + value1);

        // It returns an Byte object holding the byte value 
        // denoted by the given String argument by calling 
        // value1.decode(str)

        Byte result = value1.decode(str);

        // Display result
        System.out.println("value1.decode(str): " + result);
    }
}

Output

value1:100
value1.decode(str): 20
