Convert an Object Array to String in Java

Declaration :

public static String toString(Object[] a)

1	public static String toString(Object[] a)

Explanation :

Purpose	The java.util.Arrays.toString(Object[] a) method returns a string representation of the contents of the specified Object array. If the array contains other arrays as elements they are converted to strings by the Object.toString() method inherited from Object which describes their identities rather than their contents.
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 an object array
		Object[] arrObj = new Object[] { 10, 20, 30, 40, 50 };
		// Print the object array
		System.out.println("The array is:");
		for (Object num : arrObj) {
			System.out.println("Element Value is " + num);
		}
		System.out.println("\nString Representation :");
		System.out.println(Arrays.toString(arrObj));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize an object array

Object[] arrObj = new Object[] { 10, 20, 30, 40, 50 };

// Print the object array

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

for (Object num : arrObj) {

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

}

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

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

}

Output of Program :

The array is:
Element Value is 10
Element Value is 20
Element Value is 30
Element Value is 40
Element Value is 50
String Representation :
[10, 20, 30, 40, 50]

The array is:

Element Value is 10

Element Value is 20

Element Value is 30

Element Value is 40

Element Value is 50

String Representation :

[10, 20, 30, 40, 50]
