the eclipse, java source code of Chinese garbled how do

It stands to reason that this is not a simple question to a simple

But today it took me a full 40 minutes to get it

It must be recorded

windows---preference--General---Content Types----Text---Java Soure File

Then go down the line of sight, in the Default encoding, you need to first delete the contents, then click the Update button to write the UTF-8 or GBK

This is because, java source file is a higher priority than other all 

If you are unsure Chinese encoding is utf-8 or gbk, then there must be such a step, otherwise, it can not always be successfully modified coding scheme;

mark ！！

I hope we all can dream, take it!
