import java.util.Arrays; public class Sorting { public static void main(String args[]) { String[] strNames = new String[] { "Beans", "Jelly", "Drive", "Language", "Mark", "Run" }; Arrays.sort(strNames);
本文从比较排序相关的两个接口(Comparable和Comparator)讲起,并以代码实例的形式,讲解了Array、List、Stream排序的方法,这应该可以覆盖大部分Java排序的使用场景。 对于其它集合类如Set和Map,一样可以进行排序处理,可以将它们转化为Stream然后再进行排序。
//Collections.sort对于实现Comparable的类进行排序List<String>names=asList("Larry","Harry","James","David");Collections.sort(names);assertEquals(names,asList("David","Harry","James","Larry")); Java Copy 提供Comparator进行排序: //Collections.sort提供Comparator进行排序List<Person>persons2=asList(ne...

Java排序 两个接口 Comparable 先上代码: packagejava.lang; publicinterfaceComparable<T>{ publicintcompareTo(T o); } 可以看出这个接口只有一个方法,这个方法只有一个参数,实现了这个接口的类就可以和同类进行比较了。这个方法所实现的,就是比较法则,也是说,它表示如何对两个对象进行比较。
1. Stream.sorted() – Java 8 Java 8 stream APIshave introduced a lot of exciting features to write code in very precise ways which are more readable. This example sorts the string array in a single line code usingStream. It uses theStream.sorted()method which helps in sorting a stream ...
out.println("Array after the use of" + " Collection.sort() :\n" + coll1); } } Output: In the given example, we observe the import of the Java.util.collections class, or alternatively, we can import all classes from java.util using java.util*. This implies that all classes ...
