The solution of  " :!java -cp %:p:h Main"  did not work out. 

I think this might be because my java files all have the following line:
Package myjavafiles;

as of yet the only way I've found to compile and run it from the terminal (and 
not from vim)
is by being in the parent directory of myjavafiles and doing:

javac myjavafiles/*.java
java myjavafiles.Main

I've found that I can specify the directory of the java files I want to compile 
in the "javac" command. But when the "java" command will only work when I'm in 
the directory that has the folder of java files. 

I came to this conclusion after doing the following in vim from myjavafiles 

// succesful
: cd ..
: !javac myjavafiles/*.java
: !java myjavafiles.Main

// not successful
: !javac *.java          <---worked
: !java Main             <----did not work

// suprisingly not successful
: cd ..
: !javac myjavafiles/*.java
: !java ~/path/to/myjavafiles.Main

Because of these tests I think that perhaps I need to change directories to 
compile. But I'm not sure how to get only the folder name "myjavafiles" instead 
of the whole path.
