public class CustomerBiz { String[] names=new String[5]; public void addName(String name){ for(int i=0;i<names.length;i++){ if(names[i]==null){ names[i]=name; break; } } } public void showName(){ for(int i=0;i<names.length;i++){ System.out.print(names[i]+" "); } } public boolean editName(String oldName,String newName){ boolean find=false; for(int i=0;i<names.length;i++){ if(names[i].equals(oldName)){ names[i]=newName; find=true; break; } } return find; } public void shownewName(){ for(int i=0;i<names.length;i++){ System.out.print(names[i]+" "); } } } import java.util.*; public class TestCustomer { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Scanner input=new Scanner(System.in); CustomerBiz c=new CustomerBiz(); for(int i=0; i<5; i++){ System.out.print("请输入客户姓名: "); String name=input.next(); c.addName(name); } System.out.println("****************************"); System.out.println("\t客户姓名列表"); System.out.println("****************************"); c.showName(); System.out.println(); System.out.print("请输入要修改的客户姓名: "); String s=input.next(); System.out.print("请输入新的客户姓名: "); String d=input.next(); if(c.editName(s, d)){ System.out.println("找到并修改成功!"); }else{ System.out.println("没找到,抱歉."); } System.out.println("****************************"); System.out.println("\t客户姓名列表"); System.out.println("****************************"); c.shownewName(); } }
