I want my stuff back!

Well, you have some of it. What do you have?

• Data: We know Java's type system has two parts:
  • Primitive types: These hold raw data and live on the stack or inside of objects.
  • Object types: These are chunks of memory on the heap.
• Variables: Varibles have type in Java, and can only refer to data of their type. Primitive type variables store their datum directly. Object type variables store a memory address in the heap.
• Conditional Logic: We have seen that if and friends work pretty much like they do in Python.
• Strings: Strings are immutable character sequences in both Java and Python. Both languages provide plenty of ways to manipulate strings.
• Classes: Both languages support classes and the creation of custom objects. All Java code must be in a class.
• Lists: Java has the ArrayList<T> type. It is a homogeneous sequence type. We will be looking at this in a great deal more detail.
• Functions: these are methods in Java

We are now going to get the rest of it. What's missing?

• Loops
• Dictionaries
• Sets
• ArrayLists and Arrays
