Java - How to convert an array of bytes i.e. byte[] to String ?

Introduction

In this post, we will explore how to convert an array of bytes i.e. byte[] to String in Java. For this functionality, we will use the following constructor of java.lang.String class

String(byte[] bytes, String enc)

Example

import java.nio.charset.StandardCharsets;

public class ByteArrayToString {

 public static void main(String[] args) {
  byte[] bytes = "a quick fox jumps over the lazy dog".getBytes();
  
  // convert the bytes to String 
  System.out.println("bytes = " + bytes);
  System.out.println( "bytes.toString() = " + bytes.toString());
  String myString = new String ( bytes , StandardCharsets.UTF_8);
  
  System.out.println("myString = " + myString);
 }
}

Output

bytes = [B@41a4555e
bytes.toString() = [B@41a4555e
myString = a quick fox jumps over the lazy dog

Conclusion

In this post, we learned how to convert an array of bytes to String.
