how to get an array as input in java

To get an array as input in Java, you can use a combination of the Scanner class from the java.util package and the nextLine() method.

Here's an example of how to get an array as input in Java:

Scanner scanner = new Scanner(System.in);

System.out.print("Enter the array: ");
String input = scanner.nextLine();

String[] elements = input.split(" ");
int[] numbers = new int[elements.length];

for (int i = 0; i < elements.length; i++) {
    numbers[i] = Integer.parseInt(elements[i]);
}

System.out.println("The array is: " + Arrays.toString(numbers));

In the above example, a Scanner object is created using the Scanner() constructor, and the nextLine() method is used to read a line of input from the user.

The split() method of the String class is then used to split the input string into an array of Strings, using a space character as the delimiter.

A new integer array called numbers is then created, with a size equal to the number of elements in the input array.

The for loop is used to iterate over the elements array and convert each element to an integer using the parseInt() method of the Integer class. The resulting integers are then stored in the numbers array.

Finally, the toString() method of the Arrays class is used to convert the numbers array to a String representation, which is then printed to the console.

For example, if the user enters "1 2 3 4 5" as the input, the numbers array will contain the following elements: [1, 2, 3, 4, 5].

For more information on reading input from the user in Java, you can refer to the documentation for the Scanner class in the Java API.
