The setByte() method of Array class is used to set the value of the indexed component of the specified array object to the specified byte value.

Syntax

public static void setByte(Object array, int index, byte b)
                    throws IllegalArgumentException,
                           ArrayIndexOutOfBoundsException

Parameter

ArrayIndexOutOfBoundsException

Example 1

//import statement

import java.lang.reflect.Array;

public class ReflectArraygetByteExample1   {
   public static void main(String[] args) {

            byte[] arr = new byte[]{1,2,3};

       for(int i=0;i<arr.length;i++)
       {
            System.out.println("arr["+i+"] = " + Array.get(arr, i));
       }     
   }
}

Output:

arr[0] = 1
arr[1] = 2
arr[2] = 3

Example 2

//import statements

import java.lang.reflect.Array;

public class ReflectArraygetByteExample2 {
  public static void main (String args[]) {
    byte[] arr = new byte[]{1,2,3};
    
    byte value = Array.getByte(arr, 1);

    System.out.println(value);
