Garbage Collection (GC) is a fundamental part of Java. Understanding how GC works is core to understanding how the Java Virtual Machine (JVM) works and will help you write better applications and to improve the performance of those applications. This course will look at all aspects of garbage collection, including looking at what ‘young’ and ‘old’ generations are, how the JVM moves objects between eden and survivor spaces, how memory is promoted into the ‘old’ generation, how different garbage collectors work and how they affect the running of your application. We will also look at ‘card tables’ and how they help manage memory in the old generation. We will examine each of the garbage collectors including the serial and parallel collectors; the CMS collector and the G1 collector. We cover the tools you can use to monitor GC including jstat and VisualVM. Finally we look at ways you interact with the GC through classes Such as Soft, Weak, and PhantomReference and their associated helpers ReferenceQueue and WeakHashMap

Java security is built around the idea of permissions and policy. Code is granted permissions based on the currently in-force policy. In this course we look at how the security manager and access controller work hand-in-hand to provide this security. The course covers how to set a security manager and how to set up and edit a policy file to grant the levels of permissions that code needs. Permissions are typically based on where code is loaded from but we also look at how to sign code, so that permissions can be based on who created a library. The course also looks at how the AccessController walk the call stack to check that a permission can be granted. While the JRE comes with a set of permissions, these are not always enough so the class covers creating and using your own permissions. Finally we cover the idea of ‘privileged scope’ which allows code to be granted some permission even when code around them should cause the grant to fail

Whether you are writing scripts for your own use, building websites with something like Flask, or using machine learning frameworks like TensorFlow, you need to use collections in Python. However, often there are multiple collection types that seem like the correct solution to your particular problem. Being able to pick the correct type is an essential skill to write effective Python code. In this course, Core Python: Hashing and More Collections, you will learn about more of the collection types in Python and be able to pick the correct type and use that type more effectively. First, you will learn how to classify collection types to be able to easily determine what kind of functionality all the advanced collection types offer. Next, you will discover how to implement __hash__ and __eq__ to make your own types more useful in mapping types. Finally, you will explore more of the collection types in Python. When you are finished
with this course, you will have the skills and knowledge of Python collection types needed to write more effective Python
