This code is a Java program that defines a class Solution with two methods:

1. arrayLength(int[] arr):

   • This is a static method that accepts an array of integers (arr) as input.
   • It simply returns the length (number of elements) of the array using the arr.length property.

2. main method:

   • This is the entry point of the program.
   • It uses a Scanner object to read user input from the console.
   • It creates an integer array arr with a fixed size of 5.
   • A for loop is used to populate the elements of the array (arr) by reading 5 integers from the user.
   • The arrayLength method is called with arr as an argument, and it prints the length of the array (i.e., 5) to the console.

Key Points:

• Input: The user must enter 5 integers, one for each element of the array.
• Output: The program outputs the size (length) of the array, which is always 5 in this case because the array size is predefined as 5.

Example Run:

If the user inputs:

10
20
30
40
50

The program will print:

5

Notes:

• The commented-out line // System.out.println(arr.length); would, if uncommented, produce the same output (5) because it directly accesses the length property of the array.
• The program demonstrates basic concepts of arrays, user input, and method usage in Java.
