How to convert an int array to string with tostring method in Java?

Question

Below is the code I’ve to use toString(int[]) method: 

int[] array = new int[lnr.getLineNumber() + 1];

int i = 0;

System.out.println(array.toString());

This is the output I get: 

[I@23fc4bec

It doesn’t give me the desired output as I want a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ``, " (a comma followed by a space). Can anyone tell me how to do this?

You have to use Arrays.toString(int[]) method for every different primitive java type: 

import java.util.Arrays;

int[] array = new int[lnr.getLineNumber() + 1];

int i = 0;

..      

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