How to convert an int array to String with toString method in Java

In Java, you can convert an int array to a String representation using the Arrays.toString() method. Here's how you can do it:

import java.util.Arrays; public class IntArrayToString { public static void main(String[] args) { int[] intArray = {1, 2, 3, 4, 5}; // Use Arrays.toString() to convert the int array to a String String intArrayAsString = Arrays.toString(intArray); // Print the result System.out.println("IntArray as String: " + intArrayAsString); } }

In this example:

  1. We have an int array named intArray containing some integer values.

  2. We use Arrays.toString(intArray) to convert the intArray to its string representation. The Arrays.toString() method formats the array elements as a comma-separated string enclosed in square brackets.

  3. We store the result in the intArrayAsString variable.

  4. Finally, we print the intArrayAsString to the console.

When you run the code, it will print:

IntArray as String: [1, 2, 3, 4, 5]

This output shows the intArray converted to a string using the Arrays.toString() method. You can use this approach to convert an int array to a string in Java.
