可能重复：
不支持的主要 .minor 版本 51.0
我制作了这个脚本，它给了我这个错误：

Exception in thread "main"
这是什么意思？这是我的代码...
package net.glitching;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.net.Socket;
public class client {
static Socket sock = null;
public static void main(String[] args) {
while (true) {
try {
sock = new Socket("localhost", 4000);
ObjectInputStream in = new ObjectInputStream(sock.getInputStream());
}
catch (IOException ex) {}
}
}
}
