    Hey timeline,

    Welcome to the Java Programming Forums

    There were a few small errors in your code. This should work:

    import java.io.*;
     
    public class IO_Tester {
     
        public static int readInt() {
           byte b[] = new byte[16];
           String str;
     
           try{
               System.in.read(b);
               str = (new String(b)).trim();
               return Integer.parseInt(str);
        }   catch (IOException e) {
            System.out.println("Exception: " + e.toString());
            return 0;
    }
    }
     
        public static float readFloat() {
            byte b[] = new byte[16];
            String str;
     
            try{
                System.in.read(b);
                str = (new String(b)).trim();
                return Float.parseFloat(str);
            }   catch (IOException e) {
                System.out.println("Exception: " +e.toString());
                return 0;
            }
        }
     
        public static String readString() {
            byte b[] = new byte[32];
            String str;
     
            try {
                System.in.read(b);
                str = (new String(b)).trim();
                return str;
            }   catch(IOException e) {
                System.out.println("Exception: " +e.toString());
                return "";
            }
        }
     
        public static boolean readBoolean() {
            byte b[] = new byte[16];
            String str;
     
            try {
                System.in.read(b);
                str = (new String(b)).trim();
                Boolean bool = new Boolean(str);
                return bool.booleanValue();
            }   catch (IOException e) {
                System.out.println("Exception: " +e.toString());
                return false;
            }
        }
     
    }

    I've highlighted the errors below:

    import java.io.*;

           try{
               System.in.read(b);
               str = (new String(b)).trim();
               return Integer.parseInt(str);
        }   catch (IOException e) {
            System.out.println("Exception: " + e.toString());
            return 0;
    }
    }
    [B]}[/B]
        public static float readFloat() {
            byte b[] = new byte[16];

                Boolean bool = new Boolean(str);
                return bool.booleanValue();

                return false;
