This can be done in two simple ways
Using ClassLoader.getResourceAsStream
This method can be used to load any file from CLASSPATH
InputStream in =this.getClass().getClassLoader().getResourceAsStream(“MyFile.txt”);
Using Class.getResourceAsStream
This method can be used to load files using relative path to the package of the class
InputStream in =this.getClass().getResourceAsStream(“SomeTextFile.txt”);
This method can also be used to load any files from CLASSPATH by prefixing a “/”
