A classic use of a stack if for checking whether an expression that contains a set of different kinds of bracketing (namely parentheses, square brackets, curly brackets, angle brackets) is well formed. Such an expression is considered well formed if the open brackets match exactly the close brackets. This problem represents one portion of the design of a compiler that needs to check that all such pairs of brackets are properly balanced and nested. You will write a method that checks a given expression (a String) with characters and brackets ((), [], {}, <>), determine if it is well-formed by using the following algorithm in conjunction with a stack. Check the expression character by character. If the character is an opening bracket (characters (, [, {, <), then push it onto the stack Else if the character is a closing bracket (characters ), ], }, >), then: Check if the stack is empty. If it is, then there is no matching opening bracket. The expression is not well formed. If the stack is not empty, pop the top character off the stack, compare the current closing bracket to the top character. If they are matched brackets, continue to read next character in the expression; if they are not matched brackets, the expression is not well formed. If the end of the expression is reached, check if the stack is empty. If it is, the expression is well-formed. Otherwise, it is not well-formed. Activities 1. Start Eclipse and create a new Java package lab2, create a new class named BalanceCheck. 2. Write a static method named matchCheck(String s). It should return true if the parameter string s is well-formed; return false otherwise. (1) Your code must instantiate a Stack to contain Character class objects using the java.util.Stack class. (2) Implement the algorithm in the introduction. (3) Your code should print meaningful error message when the expression is not well-formed. For example, missing open bracket if current character is a close bracket but stack is empty, missing close bracket if the end of string is reached but stack is not empty, or mismatch brackets. 3. Write the main method in the same class, declare some strings and call the matchCheck(String s) method to check if your method works ne.
