解析文件并检测不完整的引号和双引号

Question

我不确定程序应该如何检测开始引号和结束引号，它已经可以用于其他类型的括号，但是我找不到找到识别任何类型的结束引号的解决方案。

public class Balanced {
    public static void main(String[] args) throws IOException {
        //ask the user for the file name
        Scanner key = new Scanner(System.in);
        System.out.println("File name:");
        String fileName = key.nextLine();
        File f = new File(fileName);
        //create the reader object
        BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(f)));
        //allowed set of parenthesis
        String paranthesis = "(){}[]<>";
        //string builder to get the string of parenthesis
        StringBuilder paraString = new StringBuilder("");
        int ch;
        char c;
        try{
            //read the file and generate the string
            while((ch = reader.read()) != -1){
                c = (char)ch;
                //System.out.print(c);
                if(paranthesis.indexOf(c)!=-1){
                    paraString.append(c);
                }
            }
        }
        catch (Exception e){
            System.out.println(e.getMessage());
        }
        //pass the string and file name to the checker method
        checker(paraString.toString(),fileName+"Output.txt");
    }
    public static void checker(String paraString,String filename) throws IOException{
        //crate new Stack
        Stack<Character> stack = new Stack<>();
        //status = 0 means sucess
        int status = 0;
        //create new file object
        File f = new File(filename);
        //writer object to write
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(f)));
        //loop through each character and check for the status
        for (char ch: paraString.toCharArray()) {
            if(ch == '(' || ch == '{' || ch == '<' || ch == '[' || ch == '\"' || ch == '\''){
                stack.push(ch);
            }
            else {
                char top = stack.peek();
                if(ch == ')' && top != '('){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "(" + "> "+ "expected");
                }
                else if(ch == '}' && top!='{'){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "{" + "> "+ "expected");
                }
                else if(ch == ']' && top!='['){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "[" + "> "+ "expected");
                }
                else if(ch == '>' && top!='<'){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "<" + "> "+ "expected");
                }
                   else if(ch == '"' && top!='"'){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "<" + "> "+ "expected");
                }
                    else if(ch == '\'' && top!='\''){
                    status  = 1;
                    writer.write(ch + " expected\n");
                    writer.write( "<" + "<" + "> "+ "expected");
                }
            }
            //is status become 1 break out of the loop
            if(status==1){
                break;
            }
        }
        //if status is 0 then write sucess message
        if(status==0){
            writer.write("File Successfully parsed.\n");
         }
        writer.close();
    }
 }

解析器应该能够识别是否缺少引号，我已经尝试过其他用于REGEX的方法，但是它们不起作用，并且希望以一种我可以理解的简单方式得到建议。
