java程序设计？
下面是BankAccount类的代码：
public class BankAccount {
private String name;
private double balance;
private int year;
private double rate = 0.01d;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getRate() {
return rate;
}
public void setRate(double rate) {
this.rate = rate;
}
public double getBalance() {
return balance;
}
public BankAccount() {
this.balance = 10d;
this.year = 1;
}
public BankAccount(double balance, int year) {
this.balance = balance;
this.year = year;
}
public void save(double balance, int year) {
this.balance = this.balance + balance;
this.year = year;
}
public void fetch(double balance) {
this.balance = this.balance - balance;
this.year = 0;
}
public double calcTotal() {
return this.balance * this.rate * this.year + this.balance;
}
}
下面是BankTest类的代码：
public class BankTest {
public static void main(String[] args) {
BankAccount account = new BankAccount(1000d, 3);
account.setName("Tom");
account.save(2000d, 3);
System.out.println("该账户的姓名：" + account.getName());
System.out.println("该账户的存款额：" + account.getBalance());
System.out.println("该账户的总金额：" + account.calcTotal());
}
}
下面是运行结果：
麻烦您看一下，是否能够满足要求。

大哥~~我还回答了你另一个“编程题”的问题（），运行过了，没问题的，你记得处理那个问题啊~~^_^呵呵……
这个Java程序设计题怎么做
DecimalFormat df = new DecimalFormat();
df.applyPattern("0.00");
double p = 160;
double w = 1000;
double d = 0;
Scanner sc = new Scanner(System.in);
System.out.print("请输入任意s值：");
double s = sc.nextDouble();
if (s 0 s 250) {
d = 0;
} else if (s = 250 s 500) {
d = 0.02;
//System.out.println(s);
} else if (s = 500 s 1000) {
d = 0.05;
} else if (s = 1000 s 2000) {
d = 0.08;
} else if (s = 2000 s 3000) {
d = 0.1;
} else if (s = 3000) {
d = 0.15;
}
double exp = p * w * s * (1 - d);
System.out.println(df.format(exp));

JAVA程序设计题（很简单的）
你的题有很多错误，我给你改了一下。
1.设变量i和j的定义如下，试分别计算下列表达式的值：
int i=1; double d=1.0;
1题 35/4 [8]
2题 46%9+4*4-2 [15]
3题 45+43%5*（23*3%2）[48]
4题 45+45*50%i-- [45]
5题 45+45*50%（i--） [45]
6题 1.5*3+（++d） [6.5]
7题 1.5*3+d++ [5.5]
8题 i+=3/i+3 [7]
程序阅读题
1给定如下代码，写出程序运行结果
class Example{
public static void main(String arges[]){
int i=0;
do{
System.out.println("doing it for i is:"+i);
}while(--i0);
System.out.println("finish");
}
}
结果如下：
doing it for i is:0
finish
2 阅读程序段写出执行结果
for(int k=1;k=5;k++){
if(k4)break;
System.out.println("k="+k);
}
结果：
k=1
k=2
k=3
k=4
3试写出下列程序段循环的运行结果
int i=1;
while(i10)
if(i++%2==0)
System.out.println(i);
结果：
3
5
7
9
操作题
求1!+2!+...+10!
public static void main(String arges[]){
long sum = 0;
for(int i = 1; i = 10; i++) {
long s = 1;
for(int j = 1; j = i; j++) {
s *= j;
}
sum += s;
}
System.out.println("sum = " + sum);
}
求100之内的所有“完数”。完数是指等于它的因子和的数。例如：6=1+2+3，6=1*2*3，则6是一个完数
public class wanshu{
public static void main(String[] args) {
for(int i = 1; i = 100; i++) {
if(fun(i)) {
System.out.println(i);
}
}
}
public static boolean fun(int num) {
int sum = 0;
for(int i = 1; i num; i++) {
if(num % i == 0) {
sum += i;
}
}
return num == sum;
}
}
