[英]Java Object->String[] to String[]
I have an Object variable that contains a String[] array, and I am trying to do the following 我有一个包含String []数组的Object变量,并且我正在尝试执行以下操作
String[] arr = ((String[])packet.getObject());
I however recieve the dreaded ClassCastException. 但是,我收到了可怕的ClassCastException。 What information do you guys need?
你们需要什么信息? My packet class looks as the following:
我的数据包类如下所示:
public class Packet implements Serializable {
private static final long serialVersionUID = 1L;
private int type;
private Object object;
public Packet(int type, Object object) {
this.type = type;
this.object = object;
}
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
public Object getObject() {
return object;
}
public void setObject(Object object) {
this.object = object;
}
}
Any ideas? 有任何想法吗? I'm trying to convert the Object into a String[].
我正在尝试将对象转换为String []。
If you get a ClassCastException, it means that the packet does NOT hold a String[]
. 如果收到ClassCastException,则表示该数据包不包含
String[]
。
Execute the following code to see what it actually holds, then debug to see why and where the object is stored in the packet: 执行以下代码以查看其实际内容,然后调试以查看对象在包中存储的原因和位置:
System.out.println(packet.getObject());
System.out.println(packet.getObject().getClass());
A debugger would give you this information without needing to modify the code. 调试器将为您提供此信息,而无需修改代码。
