Comparable Comparator are used to implement the comparison and sorting of elements in the collection, except that comparable is the sort of method implementation defined within the collection, Comparator is the sort implemented outside the collection, so, if you want to implement sorting, You need to define a method for the Comparator interface outside of the collection or to implement the

Here is a brief introduction to Java's comparable internal comparator and comparator external comparator usage implementationSo let's do a sort of between objects, first build a model or call Javaben. As follows:The use of the 1.Java comparable internal comparator is implemented:Comparable internal comparator (to have the entity class Javaben (testcomparable) implement the

comparable and comparator in Java -comparable interfaceInterface definitionpublicinterface ComparableT> { publicint compareTo(T o); } The interface contains only one CompareTo () function,int CompareTo (object o): Compares the current instance object with the object o, returns a negative value if it precedes the object o, returns 0 if two objects are in the same position in the sort, and retu

Comparablecomparable is the sort interface.If a class implements the comparable interface, it means "this class supports sorting." The class that implements the comparable interface supports sorting, assuming that there is now a list (or array) of objects for the class that implements the comparable interface, the list (or array) can be passed through Collections

When a collection or array that needs to be sorted is not a purely numeric type, you can usually use comparator or comparable to implement object sorting or custom sorting in a simple way. The following two examples are used to sort the age of the user object using comparable and comparator respectively.1. By implementing the comparable interface, sort according

First, describeCustom classes are sorted in a certain way, such as when a person class is ordered from small to large according to age, such as a student class to be ranked from highest to lowest by grade.Here we take two ways, one is to use the comparable interface: the class to which the object is to be sorted implements the comparable interface, and overrides the CompareTo () method in the

interface comparable and comparator differences and relationships1). Both are the implementation of the collection of elements in the comparison, sorting;2). Comparable is a collection of internally defined method implementation ordering, comparator is a collection of external implementation ordering3). Comparator interface under Java.util, comparable interface u

When a collection or array that needs to be sorted is not a purely numeric type, you can usually use comparator or comparable to implement object sorting or custom sorting in a simple way. The following two examples are used to sort the age of the user object using comparable and comparator respectively. 1. By implementing the comparable interface, sort according

Comparable introduction Comparable is the sort interface. If a class implements the comparable interface, it means "this class supports sorting." The class that implements the comparable interface supports sorting, assuming that there is now a list (or array) of objects for the class that implements the

comparable Comparator are used to implement sorting in the collection, just comparable the sort that is implemented within the collection, Comparator is the sort that is implemented outside the collection, so, if you want to implement the sort, A method to define the comparator interface outside the collection compare () or to implement the comparable interf

The Java comparator has two classes, namely the comparable interface and the comparator interface .When sorting an array of objects, the comparator works very clearly, first of all, to explain the comparable interface. Let the object that needs to be sorted implement the comparable interface, override the CompareTo (T O) method in which you define the collation,

Comparable and comparator interface difference analysis in JavaSource: Code Farming Network | Time: 2015-03-16-10:25:20 | Hits:8902 [Introduction] This article is to be detailed analysis of Java comparable and comparator interface differences, both have a comparative function, then what is the difference, interested Java developers continue to look at it.
