java数组循环问题 | 码农家园

java array loop issue

本问题已经有最佳答案，请猛点这里访问。

我有一个特殊的问题，当在数组中分配循环中的元素时，事情会发生。

当我移出循环并检查时，所有索引的相同数组值将被设置为最后一个索引的值。下面是代码

JSONObject js = new JSONObject(json_string);
JSONArray jsonArray=js.getJSONArray("customer");
DataModelCollection[] dataModelCollection = new DataModelCollection[7];

for (int i=0;i<jsonArray.length();i++) {

JSONObject json = jsonArray.getJSONObject(i);

amont = json.getLong("BalanceAmount");
custName = json.getString("CustName");
partitionKey = json.getInt("PartitionKey");
String date1 = json.getString("date");

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = df.parse(date1);

dataModelCollection[i] = new DataModelCollection();

dataModelCollection[i].setName(custName);
dataModelCollection[i].setAccountNo(partitionKey);
dataModelCollection[i].setAmount(amont);
dataModelCollection[i].setCollectedDate(date);

Log.i("inside_loop",""+dataModelCollection[i].getName());

}

Log.i("outside_loop",""+dataModelCollection[0].getName());
Log.i("outside_loop",""+dataModelCollection[1].getName());
Log.i("outside_loop",""+dataModelCollection[2].getName());
Log.i("outside_loop",""+dataModelCollection[3].getName());
Log.i("outside_loop",""+dataModelCollection[4].getName());
Log.i("outside_loop",""+dataModelCollection[5].getName());
Log.i("outside_loop",""+dataModelCollection[6].getName());

当我打印inside_loop时，它基本上是在循环中，值会正确显示。当执行出来并检查"outside_loop"时，所有索引的值都变为dataModelCollection[6].getname()-这是最后一个索引的值。amount、date、partitionKey也是如此。

不知道我哪里弄错了。

不管它的价值是什么，这里的DataModelCollection模式类：

public class DataModelCollection {

public static long accountNo;
public static String name;
public static double amount;
public static Date collectedDate;

public DataModelCollection(long accountNo, String name, double amount, Date collectedDate) {
this.accountNo = accountNo;
this.name = name;
this.amount = amount;
this.collectedDate = collectedDate;
}

public DataModelCollection() {

}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public double getAmount() {
return amount;
}

public void setAmount(double amount) {
this.amount = amount;
}

public Date getCollectedDate() {
return collectedDate;
}

public void setCollectedDate(Date collectedDate) {
this.collectedDate = collectedDate;
}

public long getAccountNo() {
return accountNo;
}

public void setAccountNo(long accountNo) {
this.accountNo = accountNo;
}

我真的不知道是什么导致了这种情况。请帮忙。
