search a jar for classes containing a specified method name

search a jar for classes containing a specified method name

usage:
findClassMethod.sh jarClassPath [method-name]
jarClassPath - if alone, list all classes from the jar/class
method-name - list only classes containing the method-name

examples:
./findClassMethod.sh /usr/java/jdk1.8/jre/lib/ext/dnsns.jar lookupAllHostAddr
find path -type f -name '*.jar' -exec ./findClassMethod.sh {} methodXY ;
find path -type f -regex '.+.jar|.+.class' -exec ./findClassMethod.sh {} methodXY ;

sample output:

$ ./findClassMethod.sh test/test_jar.jar toString
