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.  
4. public class ByteArrayToString {
5.    /*
6.    * This method converts a byte array to a String object.
7.      */
8.  
9.     public static void convertByteArrayToString() {
10.  
11.         byte[] byteArray = new byte[] {78,73, 67,69};
12.         String value = new String(byteArray);
13.        System.out.println(value);
14.  
15.     }
16.  
17.     public static void main(String[] args) {
18.         ByteArrayToString.convertByteArrayToString();
19.     }
20.  
21. }

Output:

1. NICE

 

Convert String to Byte Array:

1.  package com.instanceofjava;
3. public class StringTOByteArray{
4.    /*
5.    * This example shows how to convert a String object to byte array.
6.      */
7. 
   
8.     public static void main(String[] args) {
9.       
10.     String data = "Instance of java";
11.  
12.     byte[] byteData = data.getBytes();
13.  
14.     System.out.println(byteData);
15.  
16.     }
17.  
18. }

Output:
