遍历每个项目并在数组Java中检查项目的值

Question

我在Java中有以下代码，可从Firebase中提取数据：

myRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
        for (DataSnapshot child: dataSnapshot.getChildren()) {
            FirebaseData ShiftMap = child.getValue(FirebaseData.class);
       }

}

模型类Firebase数据为：

@IgnoreExtraProperties
public class FirebaseData {

public String Operator;
public double Ora00;
public double Ora01;
public double Ora02;
public double Ora03;

public FirebaseData() {
    // Default constructor required for calls to DataSnapshot.getValue(Post.class)
    }

    public FirebaseData(String operator, double ora00, double ora01, double ora02, double ora03)
    {
       this.Operator = operator;
       this.Ora00 = ora00;
       this.Ora01 = ora01;
       this.Ora02 = ora02;
       this.Ora03 = ora03;
    }
}

我如何遍历每个项目以检查其价值。

现在我正以这种方式这样做，但是我认为这不是正确的方式：

myRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
        FirebaseData ShiftMap = child.getValue(FirebaseData.class);

if (!Map.Operator.isEmpty())
                {
                    if (ShiftMap .Ora00 == 0)
                    {
                        //Do Something
                    }
                    else if (ShiftMap .Ora00 == 0.5)
                    {
                        //Do Something
                    }
                    else if (ShiftMap .Ora00 == 1)
                    {
                        //Do Something
                    }

}

@AlexMamo要求的是数据库结构：

[
{       
    "Operator": "someone",
    "Ora00": 0,
    "Ora01": 0,
    "Ora02": 0,
    "Ora03": 0,        
},
{        
    "Operator": "someone",
    "Ora00": 0,
    "Ora01": 0,
    "Ora02": 0,
    "Ora03": 0,        
}
]
