网课上的排序没有中文的,查了一下,大概得这么写:
package DemoCollections;
import java.text.Collator;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.Locale;
public class DemoCollectons01 {
public static void main(String[] args) {
ArrayList<String> list = new ArrayList<>();
Collections.addAll(list,"what","the","Fuck");
Collections.shuffle(list);
System.out.println(list);
Collections.sort(list);
System.out.println(list);
System.out.println("=======================");
ArrayList<Person> list1 = new ArrayList<>();
list1.add(new Person(8,"朱柏澍"));
list1.add(new Person(9,"潘卓成"));
list1.add(new Person(55,"王奎智"));
list1.add(new Person(1,"古力娜扎"));
// Collections.sort(list1);
System.out.println(list1);
Collections.sort(list1, new Comparator<Person>() {
@Override
public int compare(Person o1, Person o2) {
Comparator<Object> comparator = Collator.getInstance(Locale.CHINA);
return comparator.compare(o1.getName(),o2.getName());
}
});
System.out.println(list1);
}
}
