Java.lang.parseInt() and NT???

Question

Please help;
When I compile It is fine but when I run it it gives this message.
C:\jdk1.3.1_01\Html\classes>java myRectangle1
Enter Width:
34
java.lang.NumberFormatException: 34
at java.lang.Integer.parseInt(Integer.java:423)
at java.lang.Integer.valueOf(Integer.java:516)
at RecHW.run(myRectangle1.java:16)
at java.lang.Thread.run(Thread.java:484)
Here is the source code:
import java.io.*;
import java.lang.*;
import Shapes.Rectangle;
class RecHW implements Runnable {
Rectangle rect;
Thread kicker=null;
public void run() {
try {
int w,h;
char ch;
StringBuffer str=new StringBuffer();
System.out.println("Enter Width:");
while((ch = (char)System.in.read())!='\n') {
str.append(ch);
w = Integer.valueOf(str.toString()).intValue();
System.out.println("2");
System.out.println("Enter Height:");
str=new StringBuffer();
while((ch=(char)System.in.read())!='\n') {
str.append(ch);
h = Integer.valueOf(str.toString()).intValue();
Rectangle rect=new Rectangle(w,h);
rect.setWH(w,h);
rect.drawRect();
} catch (IOException e) {
System.out.println("Here");
public void start(Rectangle r) {
rect=r;
kicker=new Thread(this);
kicker.start();
class myRectangle1 {
public static void main(String args[]) {
RecHW rec=new RecHW();
new Thread(rec).start();

Can you tell me why an applet like this
<applet codebase="http://java.sun.com/applets/jdk/1.1/demo/NervousText"code="NervousText.class" width=400 height=75>
<param name="text" value="Welcome to HotJavaTM Browser!">
<hr>
If you were using a JavaTM technology-enabled browser such as HotJava,
you would see dancing text instead of this paragraph.
<hr>
</applet>
works fine when it is loaded and when I change codebase related to a file on my computer and change the code which runs fine as a standalone, then the html page does not give what it was expected to do?
Thanks!
