JAVA小程序编写
1.JavaPow.java
import java.util.Scanner;
public class JavaPow {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("请输入一个数求平方:");
double num = sc.nextDouble();
System.out.println(num + "的平方结果是:" + Math.pow(num, 2));
}
}
2.CompareTest.java
public class CompareTest {
public static void main(String[] args) {
int a = 10, b = 8;
if(ab){
System.out.println("排序结果是:"+b+"\t"+a);
}else{
System.out.println("排序结果是:"+a+"\t"+b);
}
}
}
3.RateMoney.java
import java.util.Scanner;
public class RateMoney {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
double money=0;
double rate=0;
System.out.print("请输入汇款金额：");
money=sc.nextDouble();
if(money0){
rate=0;
}
else if(money0money=100){
rate=1;
}else if(money100money=5000){
rate=money/100;
}else{
rate=50;
}
System.out.println("汇"+money+"元钱需汇款费："+rate+"元");
}
}
三个都已经写出来了..
你好好看看吧!!
祝你早日成功!

Q1: java小程序设计求代码
Account类：
package Test;
import java.util.HashMap;
import java.util.Map;
public class Account {
private String cardId;//卡号
private String name;//姓名
private String password;//密码
private long leftAmt;//剩余金额
public MapObject, ObjectgetAccountInfo(String id){
//这里暂设一个用户信息
//实际要建一个数据库存放多个用户的信息
MapObject, Object map = new HashMapObject, Object();
map.put("cardId", "123");
map.put("name", "qwe");
map.put("password", "789");
map.put("leftAmt", 88);
//实际要通过sql语句在数据库中查询id对应的账户信息
if(id == "123"){
//这里没有考虑密码，全部返回
return map;
}
return null;
}
public void setCardId(String cardId) {
this.cardId = cardId;
}
public String getCardId() {
return cardId;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setPassword(String password) {
this.password = password;
}
public String getPassword() {
return password;
}
public void setLeftAmt(long leftAmt) {
this.leftAmt = leftAmt;
}
public long getLeftAmt() {
return leftAmt;
}
}
userOperate类：
package Test;
import java.util.HashMap;
import java.util.Map;
import java.util.Scanner;
public class UserOperate {
Account account = new Account();
public void operate(String id){
System.out.println("欢迎您使用ATM系统");
System.out.println("1--存款 2--查询");
System.out.println("3--取款 0--退出");
System.out.println("请选择操作类型【0-3】");
Scanner in = new Scanner(System.in);
int type = in.nextInt();
while(type!=0){
if(type==1){
System.out.println("请存入钞票");
type = in.nextInt();
}else
if(type==2){
System.out.println("您的银行账户信息为：");
MapObject, Object map = new HashMapObject, Object();
map = account.getAccountInfo(id);
System.out.println(map);
type = in.nextInt();
}else
if(type==3){
System.out.println("请取走您的钞票");
type = in.nextInt();
}else{
System.out.println("操作有误，请重新操作");
type = in.nextInt();
}
}
System.out.println("请尽快取走您的卡，谢谢使用！再见！");
in.close();
}
}
测试类（我放在main里）：
package Test;
public class test1 {
public static void main(String[] args){
//测试
UserOperate userOperate = new UserOperate();
//假设银行卡插入后读取到的id为123
String id = "123";
userOperate.operate(id);
}
}
运行结果：
这是很简单的一个思路，简单跑跑可以。
也不知道你要什么样的结果，如果是要一个完整的系统，那具体还得建立数据库，还有如何读取账户信息，等等。
Q2: 急求小程序，用JAVA编写
import java.util.Scanner;
public class NumberConvertor {
/**
* @param args
*/
public int input() {
Scanner scan = new Scanner(System.in);
int inputInt = 0;
while (true) {
try {
System.out.println("输入一个0-100购物小程序java代码的正整数(默认为0): ");
inputInt = scan.nextInt();
if (inputInt 0 || inputInt = 100) {
System.out.println("越界");
continue;
} else {
break;
}
} catch (Exception e) {
System.out.println("输入有误,重新输入");
break;
}
}
return inputInt;
}
public String convert(int aInt) {
String[] table = new String[] { "零", "壹", "贰", "叁", "肆", "伍", "陆", "柒",
"捌", "玖", "拾" };
String result;
String left;
String right;
int leftInt;
int rightInt;
if (aInt = 10) {
result = table[aInt];
} else {
leftInt = Integer.parseInt((String.valueOf(aInt)).substring(0, 1));
rightInt = Integer.parseInt((String.valueOf(aInt)).substring(1));
left = table[leftInt];
right = table[rightInt];
result = left + table[10] + right;
}
return result;
}
public static void main(String[] args) {
NumberConvertor nc = new NumberConvertor();
int val;
val = nc.input();
System.out.println(nc.convert(val));
}
}
