link.java

这是我在学习JAVA过程中所做的一次作业,目的是创建一个电话本

import java.util.*;

public class link {

	
	private Vector conects;

	public link()  {

		conects = new Vector();
	}

	public void addModifyContact (String name, String phoneNumber)  {
		zhixin conect;
		
		conect = lookUpContact(name);
		if (conect != null) {
			conects.remove(conect);
		}
		conect = new zhixin(name, phoneNumber);
		conects.add(conect);
	}
	
	public zhixin lookUpContact (String name) {
		int i = 0;
		zhixin conect1;
		while (i < conects.size())    {
			conect1 = (zhixin) conects.get(i);
			if (conect1.name.equals(name)) {
				return conect1;
			}
			i++;
		}
		return null;
	}
}
