By conventions, Java methods begin with lower case. So it's not ReadChar, but rather readChar.
To OP:
Java classes have, by convention, the first letter of its name capitalized.
Also, KeyboardReader is not a standard Java class. Input stream reader or the Scanner class introduced in Java 5 should be used.
Also, the method readChar reads, as its name suggests, a character. You should be trying to read in an integer.
Here's your code fixed:
| Code: | import TerminalIO.KeyboardReader;
public class Lol
{
public static void main (String[] args)
{
KeyboardReader reader = new KeyboardReader ();
System.out.println ("numerator is what?");
int numerator = reader.readInt ();
int denominator = reader.readInt ();
int total = numerator / denominator;
int remainder = numerator % denominator;
System.out.println ("The answer is " + total + " r" + remainder + ".");
}
}
|
Here's a the fixed code using input stream:
| Code: | import java.io.*;
public class lol
{
public static void main (String[] args)
{
try
{
BufferedReader in = new BufferedReader (
new InputStreamReader (System.in));
System.out.println ("numerator is what?");
int numerator = Integer.parseInt (in.readLine ());
int denominator = Integer.parseInt (in.readLine ());
int total = numerator / denominator;
int remainder = numerator % denominator;
System.out.println ("The answer is " + total + " r" + remainder + ".");
}
catch (IOException ioe)
{
ioe.printStackTrace ();
}
}
}
|
Here is the fixed code using Scanner:
| Code: | import java.util.*;
public class lol
{
public static void main (String[] args)
{
Scanner sc = new Scanner (System.in);
System.out.println ("numerator is what?");
int numerator = sc.nextInt ();
int denominator = sc.nextInt ();
int total = numerator / denominator;
int remainder = numerator % denominator;
System.out.println ("The answer is " + total + " r" + remainder + ".");
}
}
