Solution

Here is the correct order of the Java code:

import java.util.Scanner;

public class Main{
    public static void main(String args[]) {
        Scanner sc=new Scanner(System.in);
        int num1 = sc.nextInt();
        System.out.println("The value is "+num1);
    }
}

Explanation:

  1. First, we import the necessary libraries, in this case, java.util.Scanner which is used for getting user input.

  2. Then, we define the class. In Java, every application must contain a main class that wraps up all the code. Here, the class is named Main.

  3. Inside the class, we define the main method. This is the entry point for any Java application. The Java Virtual Machine (JVM) calls the main method when the program starts.

  4. Inside the main method, we create a new Scanner object that reads the input from the user.

  5. We declare an integer num1 and assign it the value of the next integer input from the user.

  6. Finally, we print out the value of num1 using System.out.println.
