There are usually two ways to interact with a filesystem: using a GUI (Graphical User Interface) where you point and click, and using a command line where you type commands. In Windows, the command line is called "DOS".
To open a DOS window in the St. George labs, click on Start ->
Command Prompt.
Use the following commands to navigate through the directory structure:
| command | effect |
|---|---|
dir |
list contents of current directory |
h: |
go to drive H |
cd dirName
| go to directory "dirName" |
cd..
| go up to parent directory |
cd \
| go to root directory |
dir |
list contents of current directory |
| del llama | delete file called "llama" |
| ren llama alpaca | rename file or directory "llama" to "alpaca" |
| md eek | make a new directory called "eek" |
| rd eek | remove the directory called "eek" |
Click for an exhaustive list of DOS commands. (This is not required reading.)
Note: DOS is not case sensitive but Java is. For example, Java knows
that hello, HELLO and hEllO
are not the same. DOS is not as clever.
Although you will likely have already compiled your code from within DrJava, you can also do it from DOS. Type
javac Marf.java
at the prompt, where Marf.java is the java source file.
To run a Java program type
java Marf
Where Marf is the name of the class containing the
program's main method. Note: Do not type the
.class or .java extension.
You can run javadoc either by changing directories (with
cd) or by specifying the absolute path to the source
files. The following generates the documentation for all the
.java files in the current directory:
javadoc -private *.java
The -private flag generates documentation for the
private members of your classes as well as public members. This is
appropriate when generating documentation for other programmers who
will maintain your code, and may be required for assignments.
