构造函数 Date（）未定义，大家帮帮小弟我，这个有关问题如何改

构造函数 Date（）未定义，大家帮帮我，这个问题怎么改。
程序的部分代码是这样的：

Java code


  // add an entry
    public long create(String Note) {
        Date now = new Date();
        ContentValues args = new ContentValues();
        args.put(KEY_NOTE, Note);
        args.put(KEY_CREATED, now.getTime());

        return db.insert(DATABASE_TABLE, null, args);
    }

eclipse编译提示：构造函数 Date（）未定义

系统提出的解决方案为：将参数添加至匹配项：Date（int，int，int）或Date（long)

大家说date()里面的参数应该写什么呢？

原程序的代码为：

Java code
