Class path
A class path (or class search path ) is a path to one or more directories in which a runtime environment or a development tool searches for required components, for example referenced class libraries . In Java , class paths are specified via environment variables or passed as command line parameters when a program is called .
Setting a class path in the Java compiler
If the Java compiler is used, the class path can be classpath
set with the attribute . Multiple paths must be listed separately with semicolons (under Unix-like systems with a colon).
Example in the Windows console :
javac -classpath "c:\Java\foo.jar;c:\Java\bar.jar" MySoftware.java
Explanation:
- javac is the command for calling the Java compiler.
- classpath is the option to set one or more class paths .
- c: \ Java \ foo.jar and c: \ Java \ bar.jar are the class libraries to be integrated .
- MySoftware.java is the file to be compiled.
