好吧抱歉，如果这是一个非常愚蠢的问题（我对 java 来说真的很陌生），但是我如何设置天气用户估算的储蓄或检查到 if else 语句之一。例如，如果我想存入 500 到支票或储蓄，并且我输入了储蓄，但是我如何告诉 java 他们选择了哪个账户以便它可以存款或取款？
package javaapplication3;
import java.util.Scanner
public class Transfer
{
public static void main(String[] args)
{
int checking = 1000;
int savings = 1000;
int amount = 0;
Scanner in = new Scanner(System.in);
System.out.println("ballance of checking: " + checking );
System.out.println("ballance of savings: " + savings );
System.out.println("What is the ammount you wish to deposit, transfer, or withdraw?: " );
amount = in.nextInt();
if (amount < 0 )
{
System.out.println("sorry you cant do that please only input positive amounts");
}
else
{
System.out.println(amount);
}
System.out.println("which account will you be useing checking or savings? : " );
String account = in.next();
if (account.equals("checking"))
{
System.out.println("ballance of checking: " + checking );
}
else if (account.equals("savings"))
{
System.out.println("ballance of savings: " + savings );
}
else
{
System.out.println("something went wrong" );
}
System.out.println(" will you be transferring depositing or withdrawing?: " );
String action = in.next();
if (action.equals("transfering"))
{
System.out.println("transferring: " + amount);
System.out.println("account: " + account );
}
else if (action.equals("depositing"))
{
System.out.println("depositing: " + amount);
System.out.println("account: " + account );
}
else if (action.equals("withdrawing"))
{
System.out.println("withdrawing: " + amount );
System.out.println("account: " + account );
}
else
{
System.out.println("something went wrong: ");
}
System.out.println("ballance of checking: " + checking );
System.out.println("ballance of savings: " + savings );
}
}
