How to Convert an Int Array to a String in Java using the toString Method?

Converting an Int Array to String Using toString Method in Java

In Java, when you encounter the error message "The method toString() in the type String is not applicable for the arguments (int[])", it indicates an incorrect usage of the toString method for integer arrays.

Understanding the toString Method

The Arrays class in Java provides a static method named toString that can convert an array of primitive data types (such as int[], double[], etc.) into a String representation. The output of the toString method follows a specific format:

• The array elements are enclosed within square brackets "[]".
• Adjacent elements are separated by a comma followed by a space ", ".

Correct Implementation for Int Arrays

To correctly convert an int array into a String using the toString method, follow these steps:

1. Import the Arrays Class

<code class="java">import java.util.Arrays;</code>

2. Use the Arrays.toString Method

<code class="java">int[] array = new int[lnr.getLineNumber() + 1];
System.out.println(Arrays.toString(array));</code>
