Hi there
Ok here is how you can do it.
In this example your java file is on Windows
desktop.
Step 1:
Open a new file in notepad.
Step 2:
Type the following line in notepad>
cd\windows\desktop
Step 3:
On the next line type the following>
javac yourFile.java
Step 4:
On the next line type the following>
java yourFile
Step 5:
Save this file as "Whatever.bat" on windows
desktop, make sure you put the quotation marks around it as somtimes it will save
the file as Whatever.bat.txt and you will be wondering why it wont work.
Then you simply just double click on the batch file.
You can also create a shortcut to this batch file.
Good Luck Phill

Hi there
If the man with the computer has
his "Path" set correctly,
then the batch file that i posted is all
that you need.
It changes the working directory to where the class file is,
and dos will find javac.exe and java.exe if he has set his path correctly.

Phill.
