The simplest way to print an array in Java is to use the toString() method of the Arrays class. The toString() method takes an array as a parameter and returns a string representation of the array.

For example, the following code prints an array of integers:

import java.util.Arrays;

public class Main {

  public static void main(String[] args) {
    int[] array = {1, 2, 3, 4, 5};

    String arrayString = Arrays.toString(array);

    System.out.println(arrayString); // [1, 2, 3, 4, 5]
  }
}

You can also use a for loop to print an array. Here is an example:

import java.util.Arrays;

public class Main {

  public static void main(String[] args) {
    int[] array = {1, 2, 3, 4, 5};

    for (int element : array) {
      System.out.println(element);
    }
  }
}

This will print the elements of the array one by one.

Here is a comparison of the two methods:

Method Pros Cons
Arrays.toString() Simple and easy to use. Does not allow you to customize the output.
For loop Allows you to customize the output. More complex and requires more code.

The best method to use depends on your specific needs. If you need a simple and easy way to print an array, then the Arrays.toString() method is a good choice. If you need more control over the output, then you can use a for loop.
