Java编程过程中,Integer对象(或其它继承自Number类的包装类对象)使用Number包装类内置的compareTo()方法来比较调用对象和参数之间的大小的时候,Java的集成开发环境IDE或编译器给出了提示:The method compareTo(Integer) in the type Integer is not applicable for the arguments (Float),后类似的提示,这是怎么回事呢?

The comparison is based on the Unicode value of each character in the strings. The method returns 0 if the string is equal to the other string. A value less than 0 is returned if the string is less than the other string (less characters) and a value greater than 0 if the string is...

The Java String compareTo() method is used for comparing two strings lexicographically. Each character of both the strings is converted into a Unicode value for comparison. If both the strings are equal then this method returns 0 else it returns positive
