Apart from setting the classpath to the environment variable, you can pass an additional classpath to Java runtime while launching the application using–classpathoption or–cpoption. Use the.(dot) to include the current path in the classpath where the.classfile has been generated. $ javac ...
To read a text file from the classpath in Java, you can use the getResourceAsStream method of the ClassLoader class to get an InputStream for the file, and then use a BufferedReader to read the contents of the file. Here's an example of how you can read a text file from the ...
