When compiling I get msg: Class java.io.* not found in import.

Question

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
public class CheckNumber {
//program that checks the input buffer has valid integer value
     public static void main(String[] args) {
          String inLine = null;
          int checkInteger = 0;
          try {
          BufferedReader inStream = new BufferedReader (new InputStreamReader(System.in) );
          System.out.print("Enter a valid Integer and hit <ENTER>: ");
          inLine = inStream.readLine();
          checkInteger = Integer.parseInt(inLine);
          } catch (NumberFormatException nfe) {
          System.out.println("You did not enter a valid Integer: " + nfe);
          return;
          } catch (IOException e) {
          System.out.println("IOException: " + e);
          return;
          System.out.println("You entered a valid Integer: " + checkInteger);
Compiling produced the following output:

I recently did a standard installation of jdk 1.5.
This is the first time I am trying import.
I set the path:
set path=c:\jdk\bin
Hmm...
C:\jdk\bin>java -version
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Client VM (build 1.5.0_15-b04, mixed mode, sharing)
C:\jdk\bin>javac -J-version
'javac' is not recognized as an internal or external command,
operable program or batch file.
There's no javac.exe file.
I have javaw.exe and java.exe.
