hi
i'm a newbie. i have jdk1.2.2 for win98. i used notepad as editor and when i tried to save my first program as Welcome1.java it saved the file as Welcome1.java.txt. so i can't compile it. what i'm doing wrong?

Hi akmsr,

When you type in the name of the file add quotes around it, so name it:

"Welcome1.java"

If you don't add quotes it adds the .txt extension.

Hope that helps.

akmsr,

You need to add a path. Find the directory where the java compiler is and add this to your autoexec.bat:

PATH C:\Java\bin\

where C:\Java\bin\ is the directory where your java compiler is. That way you can the run the java compiler from any directory, not just the directory where the compiler is. Now just type

java filename

in any directory and it should work (as long as filename exists in that directory). Also, you may want to use a text editor more powerful than notepad. I recommend EditPad Lite. It's free and easy to use and it lets you open more than one file at a time (using tabs).

Hope that helps.

akmsr,

Here is how to do it, directly from the Sun Java readme:

To set the PATH permanently, open the AUTOEXEC.BAT file and add or change the PATH statement as follows: 1. Start the system editor. Choose "Start", "Run" and enter sysedit, then click OK. The system editor starts up with several windows showing. Go to the window that is displaying AUTOEXEC.BAT. 2. Look for the PATH statement. (If you don't have one, add one.) If you're not sure where to add the path, add it to the right end of the PATH. For example, in the following PATH statement, we have added the bin directory at the right end: PATH C:\WINDOWS;C:\WINDOWS\COMMAND;C:\JDK1.2.2\BIN Capitalization doesn't matter. The PATH can be a series of directories separated by semi-colons. Microsoft Windows searches for programs in the PATH directories in order, from left to right. You should only have one bin directory for the Java 2 SDK in the path at a time (those following the first are ignored), so if one is already present, you can update it to 1.2.2. 3. To make the path take effect in the current Command Prompt window, execute the following: C:> c:\autoexec.bat 4. To find out the current value of your PATH, to see if it took effect, at the command prompt, type: C:> path

Hope that helps.
