Convert Array to String in Java

Java – Convert Array to String

To convert Array to String in Java, call Arrays.toString() method and pass the array as argument. Arrays.toString() returns a String with the elements enclosed in square brackets.

Examples

In the following example, we take two integer arrays: arr1 and arr2, and check if these two arrays are equal using Arrays.equals() method.

Main.java

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] arr = {25, 87, 69, 55};
        String str = Arrays.toString(arr);
        System.out.println(str);
    }	
}

Output

[25, 87, 69, 55]

Now, let us take an array of Strings, convert this array to String, and print to console.

Main.java

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        String[] arr = {"apple", "banana", "cherry"};
        String str = Arrays.toString(arr);
        System.out.println(str);
    }	
}

Output

[apple, banana, cherry]
