Usage

java -jar JavaMethodExtractor.jar [option(s)] source_file

options
- (none): outputs methods in their appearance order
- -s : outputs methods in the lexicographic order
- -c : constructors are also included in the list
The output format is as follows.
"file_name class_name#method_name(arg_list):return_type start_line_number end_line_number"

The arg_list consists of the types of the arguments.
Example of using on Unix:
running for all Java source files in dir

find dir -name '*.java' -exec java -jar JavaMethodExtractor.jar [option(s)] \{\} \;
