Solution

The method used to read an integer value from the user in the Scanner class is nextInt(). Here is a step by step guide on how to use it:

  1. First, you need to import the Scanner class from the java.util package. You can do this by adding import java.util.Scanner; at the beginning of your Java program.

  2. Next, you create an instance of the Scanner class. You can do this by adding Scanner scanner = new Scanner(System.in); in your main method. This tells Java that you want to use the Scanner to read input from the user.

  3. Now, you can use the nextInt() method to read an integer input from the user. You can do this by adding int number = scanner.nextInt(); This line of code will wait for the user to enter an integer, and then store that integer in the variable number.

  4. Don't forget to close the scanner after you're done using it to prevent resource leaks. You can do this by adding scanner.close(); at the end of your main method.

Here is a simple program that reads an integer from the user:
