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?
I dont have difficulty in identifying Date, Number or String. My problem is actually inside the compare method. How can I? As I said The searchText is a tuff thing. And James got it right. But I need a java based solution.Stan James (instanceof Sidekick) Posts: 8791 posted 18 years...
In Java programming, comparing integers is a fundamental operation for decision-making and ordering elements in various applications. While relational operators like<and>are commonly used for basic comparisons, thecompareTomethod provides a more nuanced approach. This method is particularly useful when de...

在Java中,CompareTo方法是Comparable接口的一个方法,用于实现对象的自然排序。在实现CompareTo方法时,通常会使用以下三种方式: 相等:如果两个对象相等,则返回0。 大于:如果当前对象大于另一个对象,则返回大于0的值。 小于:如果当前对象小于另一个对象,则返回小于0的值。 这种实现方式可以方便地比较两个对象的大小或...
