我的一个方法中有一个名为“amount”的变量,但我需要在另一个方法中引用它。我不确定使用的语法。
以下是代码:
public static void startup()
{
String message = "Welcome to Toronto Mutual!";
//prompts user to enter their employee ID
String logIn = JOptionPane.showInputDialog("Please enter your employee `enter code here`ID.");
int employeeID = Integer.parseInt(logIn);
String input = JOptionPane.showInputDialog("Please enter the transaction `enter code here`type, bank ID and amount all separated by a comma.");
input=input.toUpperCase();
if (input.equals("END")){
JOptionPane.showMessageDialog(null,"Goodbye.");
System.exit(0);
}
else
{
int balance = 100;
String []transaction = new String[3];
transaction = input.split(",");
String type = transaction[0];
int bankID = Integer.parseInt(transaction[1]);
type=type.toUpperCase();
... // there's more but it's irrelevant
如何在方法之外使用变量“amount”和“bankID”?
答案 0 :(得分:1)
两种方式:
通过参数
将amount
传递给另一个方法
private void otherMethod(int amount) {...}
创建一个实例变量,以便您可以在类范围内访问它
private int amount;
如果你选择这条路线,最好使用getter和setter。
public int getAmount() {
return amount;
}
public void setAmount(int amount) {
this.amount = amount;
}
