question: public static boolean startsWithIgnoreCase ( String src , String subS , int startIndex ) { String sub = subS . toLowerCase ( ) ; int sublen = sub . length ( ) ; if ( startIndex + sublen > src . length ( ) ) { return false ; } int j = 0 ; int i = startIndex ; while ( j < sublen ) { char source = Character . toLowerCase ( src . charAt ( i ) ) ; if ( sub . charAt ( j ) != source ) { return false ; } j ++ ; i ++ ; } return true ; }
target:  Tests if this string starts with the specified prefix with ignored case and with the specified prefix beginning a specified index.
