Compiling and Launching

javac

• javac by default places the generated class files in the same directory as the source files.
• use the javac -d option to place the class files in some other directory.
• if the directory does not exist, there will be an error.
• the directories for the package structure will however be automatically created by javac.

• Options:
• -classpath and -cp are the same.
• The argument can be the path to the directory which contains the package structure of the class files.
• The argument can be the location of the jar file - including the file name (which contains the package structure of the class files.)
