I want to decrease the line spaces of the java codes in the following latex. I already used setstretch0.4 but it seems that this code does not work for listing contents. how should I do this??

beginfilecontents*FristProgram.java
import java.io.*;
class ShowFile


 endfilecontents*

The lineskip= parameter in your lstdefinestyle controls this. Try changing it to lineskip=-.1cm, for example:

With the original setting, lineskip=.1cm, it gives this:

just show, that Steven B. Segletes's solution also work with my answer on your previous question:

beginfilecontents*FristProgram.java
