JAVA中文排序

原文出自   http://www.blogjava.net/jeff-lau/archive/2007/12/21/169257.html   感谢这位作者。

 

以下是我仿照原文做的一个比较拼音的中文排序。

下面这段代码测试通过了的，方便大家去调试去理解。。。。我只是菜鸟学学，并没有深入的去理解。。。

但我希望，大家积极的提出问题。。。，我更希望，与大家共同进步。

 

 

当然它用到了一个lib我已经提供在附件里面。供大家下载。

 

public class Person implements Comparable<Person> {
//	Comparator<Person>
	
	public Person(){
		
	}
	public Person(String name,int age,String phone){
		this.name= name;
		this.age=age;
		this.phone= phone;
	}
	
	private String name;
	private int age;
	private String phone;
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	
	public String toString(){
		return getName();
	}
	public int compare(Person o1, Person o2) {	
		Comparator cmp = Collator.getInstance(java.util.Locale.JAPAN);
		return cmp.compare(o1.getName(), o2.getName());
	}
