running a java program

[samson jose]

What is the solution when confronted with a message like this, javac: file not found usage: javac <options> <source files> use -help for list of possibles options.
Even though java is fully installed.
The above message is gotten when trying to compile a program

it means that you have a typo in the file name and/or path to the file that you want to compile or that the file itself doesn't exist.

Please note:

• Put the file name in quotation marks if it contains spaces.
• I advise to use underscores instead of spaces in file and directory (folder) names.
• In Java, the file name should always be the class name.

wrong:

javac c:/my directory name with spaces/HelloWorld.java

This would tell the copiler to compile 4 files:

1. c:/my
2. directory
3. name
4. with
5. spaces/HelloWorld.java

correct:

javac "c:/my directory name with spaces/HelloWorld.java"
