java使用顺序表制作电子通讯录,实现添加,删除和排序的功能.

翻了半天找到以前写的，只写了部分，你可以参考一下

public class Data {

private long stuNumber

private String stuName

private long stuScore

public Data(){}

public Data(long stuNumber,String stuName,long stuScore){

this.stuNumber=stuNumber

this.stuName=stuName

this.stuScore=stuScore

}

public void setStuNumber(long stuNumber){this.stuNumber=stuNumber}

public void setStuName(String stuName){this.stuName=stuName}

public void setStuScore(long stuScore){this.stuScore=stuScore}

public long getStuNumber(){return stuNumber}

public String getStuName(){return stuName}

public long getStuScore(){return stuScore}

}

public interface LinkListIntf {

public void initList()//初始化

public int size()//获得长度

public void insertData(int n,Data listdata)

public void getData(int n)

public void deleteData(int n)

public void printList()

}

public class ListTest {

public static void main(String[] args) {

int i

Sqlist sq = new Sqlist()

Data pdata

System.out.println("--------Start----------")

System.out.println("--------Init------------")

sq.initList()

System.out.println("--------Init Over--------")

Scanner sc = new Scanner(System.in)

System.out.println("输入元素：")

for (int m = 0m <2m++) {

Data data = new Data()

System.out.print("学号 姓名 分数：")

data.setStuNumber(sc.nextLong())

data.setStuName(sc.next())

data.setStuScore(sc.nextLong())

sq.insertData(sq.size()+1, data)

}

while (true) {

System.out.println("----请选择 *** 作------")

System.out.print("1--插入；2--打印；3--删除；4--查找；5--结束")

int choose = sc.nextInt()

switch (choose){

case 1:

System.out.print("插入位置：")

int n = sc.nextInt()

Data data = new Data()

System.out.print("学号 姓名 分数：")

data.setStuNumber(sc.nextLong())

data.setStuName(sc.next())

data.setStuScore(sc.nextLong())

sq.insertData(n,data)

break

case 2:

System.out.print("打印结果： ")

sq.printList()

break

case 3:

System.out.print("请输入要删除的元素的位置： ")

int deleteLocation = sc.nextInt()

sq.deleteData(deleteLocation)

break

case 4:

System.out.print("请输入要查询的元素的位置: ")

int findLocation = sc.nextInt()

System.out.print("元素内容是： ")

sq.getData(findLocation)

break

case 5:

return

}

}

}

}

public class Sqlist implements LinkListIntf{

public static final int MAX_LEN = 100

public int listLength

private Data[] listdata = new Data[MAX_LEN]

//初始化顺序表

public void initList(){this.listLength=0}

public int size(){return this.listLength}

public void insertData(int n,Data data){

int i

if(listLength>MAX_LEN)

System.out.println("表满！")

if(n<1 || n>listLength+1)

System.out.println("插入位置越界！")

for(i=listLength-1i>=n-1i--)

listdata[i+1]=listdata[i]

listdata[n-1]=data

listLength++

return

}

public void deleteData(int n){

if(n<1 || n>listLength-1){System.out.println("删除位置不正确！")return}

for(int i=ni<listLengthi++)

listdata[i-1]=listdata[i]

listLength--

System.out.println("----删除成功！-----")

return

}

public void getData(int n){

System.out.println(listdata[n-1].getStuNumber()+" "+listdata[n-1].getStuName()+" "+listdata[n-1].getStuScore())

//return 0

}

public void printList(){

int i

System.out.println("表中信息为：")

for(i=0i<listLengthi++) {

String format = String.format(listdata[i].getStuName()+" "+listdata[i].getStuNumber()+" "+listdata[i].getStuScore())

System.out.println(format)

}

//return 0

}

}

你就怎么那么小气呢！给个几十分也不亏你！

算了，刚写的就便宜你了！

import java.util.Scanner

public class Shopping {

System.out.println("\t\t\t\t1.添加联系人信息\n")

System.out.print("\t\t\t\t2删除联系人信息\n")

System.out.println("\t\t\t\t3查看联系人信息\n")

System.out.println("\t\t\t\t4.退出")

System.out.println("请选择，输入数字或按“n”返回上一级菜单：")

System.out.println("请选择，输入数字或按“n”返回上一级菜单：")

num = scanner.nextLine()

if (num.equals("n"))

isR = true

else if(num.equals("1")){

System.out.println("添加联系人信息")

System.out.println("输入联系人的姓名: ")

num = scanner.nextLine()

String birthDayNum = num

System.out.println("输入联系人的电话: ")

num = scanner.nextLine()

String birthDayNum = num

System.out.print("是否继续添加（y/e）：")

String numJixu = scanner.nextLine()

if (numJixu.equals("y"))

isEnd2 = true

else {

isEnd2 = false

isEnd = true

}

}

else if(num.equals("3")){

System.out.println("查看联系人")

System.out.print("请输入联系人姓名：")

String snum = scanner.nextLine()

int numberNum = Integer.parseInt(snum)

}

}

就给你发这么多吧！还有一点点自己琢磨吧！我也没时间整理了！！
