我创建了这个代码来美化源代码作为编码约定。但我有一个例外。它没有给出任何错误行，并且我的代码字符串最后一个花括号被转储。如何使用此代码修复它。

    String tab = "";
    String code = "class Demo{public static void main(String[] args) {System.out.println(\"ABC\");if(\"A\".equals(\"A\")){return \"A\";}System.out.println(\"ABC\");}}";
    String outtext = code;
    String repfrom = "{";
    String repto = "{\n";
    Pattern p = Pattern.compile(repfrom, Pattern.LITERAL);
    Matcher m = p.matcher(outtext);
    StringBuffer sb = new StringBuffer();
    while (m.find()) {
        tab += "\t";
        m.appendReplacement(sb, repto + tab);

    }
    m.appendTail(sb);
    String newtext = sb.toString().replace(";", ";\n" + tab + "\b");
    p = Pattern.compile("}", Pattern.LITERAL);
    m = p.matcher(newtext);

    repto = "}\n";
    sb = new StringBuffer();
    String back = "";
    String tab2 = tab;

    while (m.find()) {
        try {
            tab2 = tab2.substring(0, tab2.length() - 2);
        } catch (Exception e) {
        }

        back += "\b";
        m.appendReplacement(sb, tab2 + back + repto + tab + back);
    }
    System.out.println(sb.toString());

我的例外是...

堆栈跟踪仅包含来自 netbeans 的代码（我假设您正在运行它）。搜索该异常和“netbeans”显示有许多关于此和 netbeans 的开放错误 - https://netbeans.org/bugzilla/show_bug.cgi?id=201450

我会尝试不同的 IDE 或在命令行上编译它。
