Topic:
Java Programming Language;;
I am new to Java and try my first example but it has one error when excute javac complier at
my working dir such as C:myjavajavac hello.java
The error message is as follows
-----------------------------------------------------
hello.java:5: class HelloWorldApplet is public, should be declared in a file named HelloWorldApplet.java
pulic class HwlloWorldApplet extends Applet{
1error,
-------------------------------------------------
And I tried it on IE with hello.html that is also error, probably casued by javac complier error shown above.
I use following the instruction from this link ,
http://www.roseindia.net/java/java-introduction/javatools/java_applet_viewer.shtml
Any idea what is wrong with this simple example? could you help me to try the example at your sides
in order to start my Java programming And I 've already including everthing of JDK command putting
into my path of C: Shell that is no problem, I could run javac, java, appletviewer in every directory of my
PC.
THanks

Yes, it run also in IEwith html.
And other question is the javac Myapplet.jave is different from javac myapplet.java , javac is sentitvie to upper and lower case. It works only for upper case of"M"
