  5. Wild cards were introduced from Java 6 . Class path entries can contain the basename wildcard character *, which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR.

    java -cp “lib/*” %MAINCLASS%
    Where %MAINCLASS% is the class containing your main method.
