Your Java installation is fine as you are recieving Java errors and such. 您将收到Java错误等错误消息，表示Java安装正常。
java.io.IOException: Invalid Http response
Java IO exceptions (Input/output) are thrown when the program can't read or write which includes obtaining the applet you are trying to run. 当程序无法读写时，将抛出Java IO异常（输入/输出），其中包括获取您尝试运行的applet。 In this case it is being thrown because it can't be downloaded and read, this is most likely due to a network fault or security setting. 在这种情况下，由于无法下载和读取该文件而将其抛出，这很可能是由于网络故障或安全设置所致。
