我要在dreamweaver里做一个公积金贷款计算器，谁会代码呀？
JAVA ?C+ ?C++ ?VB ?什么的？ 你最好去站长站找或者代码站 我以前做网页和网站都是去站长站找的 好多代码也不会 现用现学嘛
用JAVA编程一个房贷计算器
打了个电话给农行的客服(收费的),终于知道公式了。.好麻烦的公式...浪费了我15分钟的电话费。 还有在写公式的过程中遇到了计算x的y次方..谁知道java里怎么计算啊???我是自己写了个方法。.感觉有点麻烦... 注意的是利率.由于开始写的时候没考虑到小数点.所以这里都是按整数算..比如利率是7.5%就写成750..呵呵。. 不直到她公式给错了还是我没听清楚.好象公式有些不准。.明天我去银行问下。. import javax.swing.*; import java.awt.*; import java.awt.event.*; class MyFrame extends JFrame{ double a; double b; double c; double d; int ee; double f; double g; double m; double n; double o; double h; static double x; static int y; double z; String s1; String s2; JFrame jf=new JFrame("Counter"); // JPanel jp1=new JPanel(); JPanel jp2=new JPanel(); JPanel jp3=new JPanel(); JPanel jp4=new JPanel(); JPanel jp5=new JPanel(); JPanel jp6=new JPanel(); JPanel jp7=new JPanel(); JPanel jp8=new JPanel(); JPanel jp10=new JPanel(); JPanel jp11=new JPanel(); JPanel jp12=new JPanel(); JLabel jl1=new JLabel("计算器"); JLabel jl2=new JLabel("房屋单价(元/平):"); JLabel jl3=new JLabel("房屋面积(平方):"); JLabel jl4=new JLabel("首付金额(元):"); JLabel jl5=new JLabel("年利率(万分之):"); JLabel jl6=new JLabel("月还款额(元):"); JLabel jl7=new JLabel("总还款额(元):"); JLabel jl10=new JLabel("还款年限(年):"); JLabel jl11=new JLabel("本金(元):"); JLabel jl12=new JLabel("利息(元):"); JTextField jt1=new JTextField("",10); JTextField jt2=new JTextField("",10); JTextField jt3=new JTextField("",10); JTextField jt4=new JTextField("",10); JTextField jt5=new JTextField("0",15); JTextField jt6=new JTextField("0",15); JTextField jt10=new JTextField("",10); JTextField jt11=new JTextField("0",15); JTextField jt12=new JTextField("0",15); JButton b1=new JButton("计算"); JButton b2=new JButton("清空"); MyFrame(){ jf.setLayout(new GridLayout(10,1)); // jp1.add(jl1); // jf.add(jp1); jp2.add(jl2); jp2.add(jt1); jf.add(jp2); jp3.add(jl3); jp3.add(jt2); jf.add(jp3);
高分求解， Java 作业题，各位高手能否帮忙看一下？
package calculate;
public class Calculate {
private double interest;
private double loanTerm;
private double loanAmount;
public Calculate(double interest, double loanTerm, double loanAmount) {
this.interest = interest;
this.loanTerm = loanTerm;
this.loanAmount = loanAmount;
}
public double getDailyRepayments() {
double a = interest / 365;
double days = loanTerm * 365;
return a * loanAmount / (1 - 1 / Math.pow(1 + a, days));
}
public double balanceAfterDays(int d) {
double a = interest / 365;
double days = loanTerm * 365;
return loanAmount * (Math.pow(1 + a, days) - Math.pow(1 + a, d))
/ (Math.pow(1 + a, days) - 1);
}
// public static void main(String[] args) {
// Calculate c = new Calculate(0.058,10,100000);
// System.out.println(c.getDailyRepayments()*14);

Java简易贷款计算机
你也不说计算公式，不知道怎么计算，我去网上找了一个月支付款的计算公式，不知道和你题目的要求是否一样，如果不一样你就改下公式就行。 java代码如下： public class Loan { public static void main(String[] args){ double rate ;//利率 int year ; //年数 double money ; //贷款总额 double monthpay ;//月付款 Scanner sc = new Scanner(System.in); System.out.println("输入月利率："); rate = sc.nextDouble(); System.out.println("输入年数："); year = sc.nextInt(); System.out.println("输入贷款总额："); money = sc.nextDouble(); //计算月付款 monthpay = (money * rate)/Math.abs(1 - (1 / (1 + rate ) * year * 12 )); System.out.println("每月应该还贷款：" + monthpay); }}

String dateString = JOptionPane.showInputDialog("请输入贷款期（loanDate）:between 24-60");
int loanDate = Integer.parseInt(dateString);
String monthRateString = JOptionPane.showInputDialog("请输入月利率 (MonthRate):such as 0.00005");
double monthRate = Double.parseDouble(monthRateString);
double pay_Per_Month = (loanAmount+loanAmount * loanDate * monthRate)/loanDate;
