question: public static String sanitizeMethodName ( String methodName ) { assert ( methodName != null && methodName . length ( ) > 0 ) ; StringBuilder sb = new StringBuilder ( ) ; char firstChar = methodName . charAt ( 0 ) ; if ( Character . isJavaIdentifierStart ( firstChar ) ) { if ( Character . isUpperCase ( firstChar ) ) { firstChar = Character . toLowerCase ( firstChar ) ; } sb . append ( firstChar ) ; } boolean previousCharWasDropped = false ; for ( int i = 1 ; i < methodName . length ( ) ; i ++ ) { char ch = methodName . charAt ( i ) ; if ( Character . isLetterOrDigit ( ch ) ) { if ( previousCharWasDropped ) { ch = Character . toUpperCase ( ch ) ; } sb . append ( ch ) ; previousCharWasDropped = false ; } else { previousCharWasDropped = true ; } } if ( sb . length ( ) == 0 ) { sb . append ( "_method" ) ; } return sb . toString ( ) ; }
target:  Sanitizes a potential method name so it is both valid and follows Java conventions (camel-cased, no underscores, etc.).
