Basic Java Commands:
If you lose control of your console running a java program you can press Ctrl-C to close your program. If you require more memory than Windows wants to provide for a high memory program you can run a java console program called myprogram (provided you have 1450m of Xmx and 256m Xms memory):
java -Xms256m -Xmx1450m myprogram
If you wish to determine which version of java you are running enter this at the console:
java -version
If you wish to compile a file called myfile.java at the console:
javac myfile.java
If you wish to run a console application called myfile from the command line:
java myfile
To see how to run an applet from the command line first make a no frills web page called lines5.html which has the following code:
Then make an applet called lines5.java with this code:
To run the above applet and web page from the command line enter:
