ParenSymmetry

balance is found except when it's not

The strings in this array are NOT balanced

String[] falseStrings = {"(", "((", ")", "(()())((())))"};

The Strings in this array are balanced

String[] trueStrings = {"()", "(())", "(((())))", "", "(()())((()))", "( )", "( () ( ) )"};

Notice: it is okay to have spaces in the string. It is also okay to have any other character in the string.

And that means ()grand()illusion should be true And (((add (5 6)) )&^$$%^$ should be false

Write two methods:

• Write a method isBalanced that takes a string, and produces true if balanced, false otherwise. The method signature should be: public boolean isBalanced(String stringToTest);
• get isBalanced to pass all the unit tests in ParenSymmetryTest.java
• Write another method checkFile that use the first to check a file of paren strings producing a true or false for each line in the file.
• It should look like public void checkFile(String filename);

And use either TestStrings0.txt and/or TestStrings1.txt to test your work. The results of running agains the TestStrings0.txt file should be true, false, true, false, true, false, true
