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 result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal; compareTo returns 0 exactly when the #equals(Object) method would return true. This is the definition of lexicographic ordering. If two strings are...
