Make an empty stack, and read the characters to the end. If a closed symbol is read, the empty stack is wrong, and if it does not match, the stack tail character pops up. Otherwise the read-in is an open character and is pressed into the stack. Finally, if the stack is empty, returns true.Please refer to the Mystack class for details.1 Public classKuohaojiancha {2 Private Char[] item = {' (', ') ', ' [', '] ', ' {', '} '};3 PrivateMystack stack =NewMystack ();4 Private Char[] str;5

Java's collection collection framework, such as set, map, and list, does not provide any easy way to initialize. Each time you set up a collection, you add the values into it. Such as Copy Code code as follows: SetLetter.add (' a '); Letter.add (' B '); //... Very cumbersome. But with anonymous inner class words. It can be a little easier. Copy Code code as follows: Set{ { Add (' a '); Add (' B '); Add (' C '); Add (' d '); Add (' e '); Add (' f '); Add

The main uses are the following three kinds: 1. (...) Grouping. Group items into a single unit that can is used with *, +, ?, |, and,. Also Remember the characters that is the match this group for use with later references. 2. (?:...) Grouping only. Group items into a single unit, but does not remember the characters of that match this group. 3. (? =P) A Positive lookahead assertion. or (?! P ) A negative lookahead assertion.

Topic Description Description The definition satisfies the following rule string as a sequence of rules, otherwise it is not a sequence of rules: 1. An empty sequence is a rule sequence; 2. If S is the rule sequence, then (s), [S],{s} and 3. If both A and B are rule sequences, then AB is also the rule sequence. For example, the following string is a sequence of rules: (), [], (()), ([]), () [], () [()],{{}} And the following are not: (，[，]，) (, ()), ([(), Now, to give you a string consistin
