Read Integer from Console in Java

To read an integer from the console, use the Scanner class.

Scanner myInput = new Scanner(System.in);

This method allows the user to add an integernextInt().

System.out.print("Enter first integer: ");
int a = myInput.nextInt();

Similarly, enter another input in the new variable.

System.out.print("Enter second integer: ");
Int b = myInput.nextInt();

Let's see the complete example.

Example

import java.util.Scanner;
public class Demo {
　　　public static void main(String args[]) {
　　　　　　Scanner myInput = new Scanner(System.in);
　　　　　　int a;
　　　　　　int b;
　　　　　　int sum;
　　　　　　System.out.print("Enter first integer: ");
　　　　　　a = myInput.nextInt();
　　　　　　System.out.print("Enter second integer: ");
　　　　　　b = myInput.nextInt();
　　　　　　sum = a　+　b;
　　　　　　System.out.printf("Sum = %d\n", sum);
　　　}
}

The following two integer values were added from the console.

5
10

After adding values and running the program, the following output can be seen.

Enter first integer:　5
Enter second integer:　10
Sum =　15
