» » » Convert Byte Array to String

  • To convert byte array to string we have a constructor in String class which is taking byte array as an argument.
  • So just we need to pass byte array object to string as argument while creating String class object.

  1.  package com.instanceofjavaforus;
  2.  
  3. public class ByteArrayToString {
  4.    /*
  5.    * This method converts a byte array to a String object.
  6.      */
  7.  
  8.     public static void convertByteArrayToString() {
  9.  
  10.         byte[] byteArray = new byte[] {78,73, 67,69};
  11.         String value = new String(byteArray);
  12.        System.out.println(value);
  13.  
  14.     }
  15.  
  16.     public static void main(String[] args) {
  17.         ByteArrayToString.convertByteArrayToString();
  18.     }
  19.  
  20. }

Output:


  1. NICE

 

Convert String to Byte Array:

  1.  package com.instanceofjava;
  2. public class StringTOByteArray{
  3.    /*
  4.    * This example shows how to convert a String object to byte array.
  5.      */

  6.     public static void main(String[] args) {
  7.       
  8.     String data = "Instance of java";
  9.  
  10.     byte[] byteData = data.getBytes();
  11.  
  12.     System.out.println(byteData);
  13.  
  14.     }
  15.  
  16. }

  2. System.out.println prints the object reference. To print contents use System.out.write.
