Java 添加临时对象时覆盖arraylist中的对象

---

问题：为什么对象会被覆盖？我需要程序能够添加新对象，但所有地址都会被上次添加的对象覆盖

，正如@boristesspider所指出的，从变量中删除static

accounttest.Account@5c647e05 Obj2, 2, 50
accounttest.Account@33909752 Obj2, 2, 50

静态

成员？请编辑您的问题并添加您的

类。啊，我明白了。我使用了另一个应用程序的代码，它对我咆哮，要求我包含这些静态数据。我又加了一次。我显然需要学习如何使用静态。谢谢你的帮助！

public class AccountTest {


/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    final int TOTAL_ACCOUNTS = 2;  // The total number of accounts
    ArrayList<Account> account= new ArrayList<Account>(); 

    for(int x = 0;x<TOTAL_ACCOUNTS;x++){  
        Account tempAccount = new Account(); 
        Scanner input = new Scanner( System.in );
        System.out.print( "Enter the name for Customer #"+(x+1)+": ");
        tempAccount.setName(input.nextLine()); 
        System.out.print( "Enter the account number for "+tempAccount.getName()+":");
        tempAccount.setAccountNumber(input.nextInt());  //gets the account number for the temp account
        System.out.print( "Enter the internet usage for Customer #"+(x+1)+": ");
        tempAccount.setUsage(input.nextInt()); //retrieves customer usage for the temp account object

        account.add(tempAccount); //Adds the account object to the array

    }

    for(Account x:account){ 
        System.out.print(x + " ");
        System.out.print(x.getName()+", ");
        System.out.print(x.getAccountNumber()+", ");
        System.out.print(x.getUsage());
        System.out.println();
    }
   }
}

accounttest.Account@5c647e05 Obj2, 2, 50
accounttest.Account@33909752 Obj2, 2, 50

public class Account {
    public String custName; //Stores the customer name
    public int custUsage;  //Stores the customers usage
    public int custAccountNumber;  //Stores the customers account number
