我有一个方法需要将提供的银行帐户添加到我创建的数组中:
public boolean addAccount (BankAccount newAccount[]) {
if (numAccounts == 0) {
return false;
}
else {
return true;
for(int counter=0; counter<newAccount.length; counter++)
newAccount[counter] += accounts;
}
}
通过这种方法测试:
public static boolean test5() {
System.out.println("Test5: add an account to a customer.");
BankAccount b = new BankAccount();
Customer c1 = new Customer("Alice", "Smith");
customerCounter ++;
if (!c1.addAccount(b))
return false;
return c1.toString().equals("Alice Smith, " + c1.getCustomerID() + "\n" + b.toString() + "\n");
}
但是我收到一个错误,eclipse在这行中没有解决方案:
newAccount[counter] += accounts;

首先,您需要提高代码质量。重新设计您的功能和数据结构。
粘贴完整代码以了解整体结构。

如果您只想查看如何将新值添加到数组中,那么它就是......
int myArray[]={10,20,30};
int newNumber=200; //new value to be added
/*Size of an array doesn't change once it is initialized,so a new Array must be
created (with new Size )to add new values.*/
int newArray[]=new int[myArray.length+1];
//The newArray will have {0,0,0,0};
// Now copy all the data from previous array to new array.
for(int i=0;i<myArray.length;i++)
newArray[i]=myArray[i];
//Now the content of newArray is {10,20,30,0}
newArray[newArray.length-1]=newNumber;
//Now the final content of newArray is {10,20,30,200}.
现在,尽管如此,我同意@Turing85和@ Shafiul。根据您的上述代码,您最终会得到无法访问的代码以及类型不兼容错误,是的,请重新设计您的代码。
