Summary
In this chapter we discussed how Java 9 better enables us to manage processes. Prior to Java 9, process management from within Java required OS specific implementations and was less than optimal in terms of CPU use and coding practice. The modern API, with new classes like ProcessHandle, makes it possible to handle almost all aspects of processes. We listed the new API, and had simple example codes for the use of each of them. In the second half of the chapter we put together a whole application managing processes where the learned API was put into practice.
In the next chapter, we will take a detailed look at the new Java Stack Walking API released with Java 9. We will use code samples to illustrate how to use the API.
