Solution 2

exit(int status) terminates the current Java application and returns the status value to the invoking process, either another application or the operating system shell. The returned value can be used to indicate success or failure.

Solution 1

exit(0) means your program ended normally.
exit(1) or exit(n) returns a error code :)

There is no conventions about it. It's customary to use 0 as "no problem", all other values are defined by application program and should be documented by its developer. These days this value rarely used. One example: console application used as a build step in building of software project. Even in this field this feature is superseded by MSBuild which offer interface for special assemblies.
