a simple jvm wrote by java just for realized how jvm works.
It has only one useful command.
U can input "classpath;className" to invoke this classFile
if the parameter "className" is some jdk's library's classFile.It can also be loaded and u can see some informations.
Note:
1.This small toy only support jdk1.8 and u'd better already setting "JAVA_HOME" environment variable.
Because the rootClassPath depends on jdk1.8's librarys.Jdk1.9+'s catalogs are changed so it might not
be able to load jdk's library.
2.This toy only supports a few features.U can use it do some simple computings.But don't use array.
I haven't finished it.
3.If u find some bugs about it.It's very appreciate if u can fix those.Also u can give an issue.But
maybe i won't go to fix it.
