Convert a Long Array to String in Java

Declaration :

public static String toString(long[] a)

1	public static String toString(long[] a)

Explanation :

Purpose	The java.util.Arrays.toString(long[]) method returns a string representation of the contents of the specified long 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 long array
		long[] arrL = new long[] { 100, 200, 300 };
		// Print the long array
		System.out.println("The array is:");
		for (long num : arrL) {
			System.out.println("Element Value is " + num);
		}
		System.out.println("\nString Representation :");
		System.out.println(Arrays.toString(arrL));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a long array

long[] arrL = new long[] { 100, 200, 300 };

// Print the long array

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

for (long num : arrL) {

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

}

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

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

}

Output of Program :

The array is:
Element Value is 100
Element Value is 200
Element Value is 300
String Representation :
[100, 200, 300]

The array is:

Element Value is 100

Element Value is 200

Element Value is 300

String Representation :

[100, 200, 300]
