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();

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

            return 0;
        }
    }
 
    public static String readString() {
        byte b[] = new byte[32];
        String str;
 
        try {

Hey timeline,

Welcome to the Java Programming Forums :)

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

Code :

---

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:

Code :

public class IO_Tester {
 
    public static int readInt() {
       byte b[] = new byte[16];

           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];
        String str;
 
        try{

            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);

            return str;
        }   catch(IOException e) {
            System.out.println[B]("Exception: ")+e.toString());[/B]
            return "";
        }
    }
