Java Development common errors (Continuous updates)

1) the following error occurs when receiving files:

Java. Io. utfdataformatexception: malformed input around byte 19

At java. Io. datainputstream. readutf (datainputstream. Java: 617)
At java. Io. datainputstream. readutf (datainputstream. Java: 547)
At CN. ac. ICT. acceptfilefronm. run (acceptfilefronm. Java: 49)
At CN. ac. ICT. socketmanager. doflag (socketmanager. Java: 127)
At CN. ac. ICT. socketmanager. Run (socketmanager. Java: 89)

Solution: The datainputstream stream has been opened before and then obtained from the socket later. A stream exception occurs (the datainputstream stream may be incomplete). Therefore, you only need to open the socket input stream at one point to solve this problem.

2) [20:55:33-picture1__txt] project has no default. properties file! Edit
Project properties to set one.

1. Copy the default. properties file to other projects and use it directly. If the file is still incorrect, re-import the project. 2. Rename the project. properties file in the project to default. properties.
