2. Use toString() Method to Print an Array in Java
3. Use the stream().forEach() Method to Print an Array in Java
4. Use the asList() Method to Print Multidimensional Array in Java
5. Use the deepToString() Method to Print Multidimensional Array in Java

This tutorial article will introduce how to print an array in Java. There are two main ways to print an array in Java, the for loop, and Java built-in methods.

Use the for Loop to Print an Array in Java

We can use the for loop to print the array in Java. With every iteration in the for loop, we print elements of an array in Java.

The example code of printing an array in Java using the for loop is as follows.

public class PrintingAnArray {
  public static void main(String args[]) {
    int Array[] = {1, 2, 3, 4, 5};
    for (int i = 0; i < Array.length; i++) {
      System.out.println(Array[i]);
    }
  }
}

Output:

1
2
3
4
5

Use toString() Method to Print an Array in Java

The toString() method is a static method of the Array class in Java that belongs to the java.util package. We need to import java.util.Arrays in our code to use the toString() method.

The toString() method takes an array as an argument, converts/typecasts that array to the string, and returns that string. Each element of the integer array will be converted to a string.

The example code of printing an array in Java using the toString() method is as follows.

import java.util.Arrays;
public class PrintingAnArray {
  public static void main(String args[]) {
    int Array[] = {1, 2, 3, 4, 5};
    System.out.println(Arrays.toString(Array));
  }
}

Output:

[1, 2, 3, 4, 5]

Use the stream().forEach() Method to Print an Array in Java

We can use the stream().forEach() method to print the elements of the array in Java. This method takes the array as an argument and then prints its elements iteratively but without using any explicit loop.

The example code of printing an array in Java using the stream().forEach() method is as follows.

import java.util.Arrays;
public class PrintingAnArray {
  public static void main(String args[]) {
    int Array[] = {1, 2, 3, 4, 5};
    Arrays.stream(Array).forEach(System.out::println);
  }
}

In the above code, we are passing the array to the stream method, and every element of the array is printing explicitly using the forEach method.

The output of the code is as follows.

1 2 3 4 5

Use the asList() Method to Print Multidimensional Array in Java

We can use the asList() method to print the elements of the array in Java. This method accepts the array as an argument and then converts it into the list format and then we print the list.

The example code of printing an array in Java using the asList() method is as follows.

import java.util.Arrays;
public class PrintingAnArray {
  public static void main(String args[]) {
    Integer Array[] = {1, 2, 3, 4, 5};
    System.out.println(Arrays.asList(Array));
  }
}

Output:

[1, 2, 3, 4, 5]

Use the deepToString() Method to Print Multidimensional Array in Java

We can also use deepToString() to print the multidimensional array in Java. This method accepts the multidimensional array as an argument and converts that array into a string that would be printed directly.

The example code of printing a multidimensional array in Java using the deepToString method is as follows.

import java.util.Arrays;
public class PrintingAnArray {
  public static void main(String args[]) {
    int Array[][] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
    System.out.println(Arrays.deepToString(Array));
  }
}

Output:

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
