What's wrong with For Loop?

Question

package mygradeloops;

import java.io.IOException;

public class MyGradeLoops {

    public static void main(String[] args) throws IOException {
        char x = \'A\';
         


        

Answer 1

It's "double printing" because when you enter a character by pressing return, you're actually writing two characters: the character you typed, and \n (newline character).

Add a second System.in.read(); call to read the newline character:

for (x='0';x<'9';x++){
    System.out.println("Please enter in one of your grades.");

    System.in.read(); // your character
    System.in.read(); // newline

    System.out.println("Keep going!");
}

Also, initializing x to 'A' in not needed, char x; is fine. In fact, it doesn't make sense to use a char in this loop, using an int would be preferred.
