Java 将变量发送到其他类
我无法将可变余额和存款从司机转移到银行账户,有人有什么建议吗?我用的是BlueJ 下面是驱动程序类和方法-Java 将变量发送到其他类,java,class,variables,bluej,Java,Class,Variables,Bluej,我无法将可变余额和存款从司机转移到银行账户,有人有什么建议吗?我用的是BlueJ 下面是驱动程序类和方法- import javax.swing.JOptionPane; public class Driver { int choice; String number; String name; double deposit; double withdraw; double balance; //public Driver()
import javax.swing.JOptionPane;
public class Driver
{
int choice;
String number;
String name;
double deposit;
double withdraw;
double balance;
//public Driver()
public Driver()
{
String number = JOptionPane.showInputDialog("1. Deposit 2. Withdraw 3. Balance 4. Change name 5. Exit");
int choice = Integer.parseInt(number);
do
{
if( choice == 1)
{
String input = JOptionPane.showInputDialog("How much would you like to deposit?");
deposit = Integer.parseInt(input);
BankAccount b = new BankAccount();
b.Deposit();
Driver a = new Driver();
这是银行账户计划-
public class BankAccount
{
double balance = 400;
double deposit;
double withdraw;
double Interest = 1.05;
String name;
String accountNumber;
public double Deposit()
{
//String input = JOptionPane.showInputDialog("How much would you like to deposit?");
//deposit = Integer.parseInt(input);
if (deposit < 10000)
{
balance = deposit + balance;
}
return balance;
}
公共类银行账户
{
双倍余额=400;
双重存款;
双退;
双倍利息=1.05;
字符串名;
字符串accountNumber;
公众双重存款()
{
//String input=JOptionPane.showInputDialog(“您想存多少?”);
//存款=整数.parseInt(输入);
如果(存款<10000)
{
余额=存款+余额;
}
收益余额;
}
您必须在银行账户
类中使用depost方法,如下所示
public double Deposit(double deposit){
...........
}
你的驾驶等级应该是
...
b.Deposit(deposit);
...
方法调用将参数添加到存款方法中,例如b.deposit(存款);或在银行帐户类中创建构造函数。请注意,您不向类发送变量;您可以通过定义参数来接受另一个变量的值,从而将变量发送给构造函数或方法。
