question: public static String parseHumpName ( String str , boolean isFirstUpper , boolean isHump ) { str = str . toLowerCase ( ) ; if ( isHump && str . indexOf ( "_" ) != - 1 ) { boolean isUpper = false ; StringBuilder builder = new StringBuilder ( ) ; for ( char c : str . toCharArray ( ) ) { if ( isUpper ) { c = Character . toUpperCase ( c ) ; isUpper = false ; } if ( c == '_' ) { isUpper = true ; continue ; } builder . append ( c ) ; } str = builder . toString ( ) ; } if ( isFirstUpper ) { return upperFirst ( str ) ; } return lowerFirst ( str ) ; }
target:  parse str to hump type<p> if class name ,param isFirstUpper should be true,else false
