Eclipse Coding Issues

Typically, Mac and Windows encoding are not the same under Eclipse. If you have a Chinese Java sources, there is usually garbled characters.

Solve---small program!

Modify the path yourself.

Run under command line

Compile.

Javac Charencodingexchange.java

Run:

Java Charencodingexchange

First, the engineering code becomes the desired encoding. This is UTF-8.

Overwrite the TMP file with the project SRC.

--------------eclipse Modifying the default encoding---------------

UTF-8

This modification of the whole project will automatically change.

UTF-8
