Convert a Byte Array to String in Java

Declaration :

public static String toString(byte[] a)

1	public static String toString(byte[] a)

Explanation :

Purpose	The java.util.Arrays.toString(bye[]) method returns a string representation of the contents of the specified byte array. The string representation consists of a list of the array’s elements enclosed in square brackets (“[]”). Adjacent elements are separated by the characters ” ” (a comma followed by a space).
Parameters	a ===> This is the array whose string representation to return.
Return Value	This method returns a string representation of a.
Exception	NA

Java Program : Example

Below example will explain java.util.Arrays.toString() method.

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize a byte array
		byte[] arrB = new byte[] { 10, 20, 30 };
		// Print the byte array
		System.out.println("The array is:");
		for (byte num : arrB) {
			System.out.println("Element Value is " + num);
		}
		System.out.println("\nString Representation :");
		System.out.println(Arrays.toString(arrB));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a byte array

byte[] arrB = new byte[] { 10, 20, 30 };

// Print the byte array

System.out.println("The array is:");

for (byte num : arrB) {

System.out.println("Element Value is " + num);

}

System.out.println("\nString Representation :");

System.out.println(Arrays.toString(arrB));

}

Output of Program :

The array is:
Element Value is 10
Element Value is 20
Element Value is 30
String Representation :
[10, 20, 30]

The array is:

Element Value is 10

Element Value is 20

Element Value is 30

String Representation :

[10, 20, 30]
