3.7 How to read input from keyboard?

1. this is a compile time error, but readInt doesn't exist, nextInt does though

2. after the second System.out.print, x should be y

3. the scanner shouldn't be initialized with a string

system.in is a string and won't actually do anything.

two variables are the same and therefore conflicts each other

in.readInt does not exist

1.lack “import java.util.Scanner;”

2.（“Systam.in"),remove" "

3.in read Int change in next Int

You all get some of the corrections, but not ALL of them. If you test your corrections in Codiva, you will see what else is missing...

correct code:

import java.util.Scanner;

public class HasError

{

public static void main(String[] args)

{

int x = 0;

int y = 0;

Scanner in = new Scanner(System.in);

System.out.print("Please enter an integer:");

x = in.nextInt();

System.out.print("Please enter another integer: ");

y = in.nextInt();

System.out.print("The sum is ");

System.out.print(x + y);

}

}
