Common Errors of running Java in eclipse

I. Eclipse Chinese annotation garbled Solution

When someone else's project or Java file is imported into their own eclipse, the Chinese comments of the Java file are often garbled, the main reason is that others' ide encoding formats are different from their own eclipse encoding formats (some GBK, some UTF-8 ).

To sum up the suggestions and experiences on the Internet, you can refer to the following solutions:

1. Change the encoding format of the entire file type

1) eclipse-> window-> preferences-> General-> content types
2) Find the type of the file to be modified (Java, JSP, etc.), there is a default encoding below, enter GBK in the input box
3) Click Update.
4) Click OK.
5) Restart eclipse

2. Change the encoding format of the entire eclipse Workspace

1) eclipse-> window-> preferences-> General-> workspacetypes
2) Change the encoding format of text files to GBK.

3. Change the encoding format of a single file

In package explorer, right-click File> properties to change the text file encoding format to GBK.

4. If the above methods still cannot be solved, you can do the following:

Use editplus to open the file to be transcoded. If there is no garbled code in editplus, you can directly copy the file content to eclipse. If editplus is garbled, You can first transcode the file in editplus, editplus-> document-> file encoding method-> change the file encoding method-> GBK, and then use eclipse to open it.

5. default encoding of Eclipse project/attribute/Text File
Modify to UTF-8,

6,

When you open eclipse, Chinese comments may be garbled. This is because the default encoding for text file encoding in eclipse is GBK. Therefore, right-click your "project ", change the other in "text file encoding" in info to UTF-8!

2. Select the code path for the project path
