Does W3SCHOOLS teach me all the syntax of the programming languages it contains?

Syntax is not important to memorize. Learning to program well is what you need to do. Syntaxes will always be google-able. More on reddit.com

What are some examples of classes/objects that you would actually use in your project?

I wouldn't say the examples are wrong. But they make it seem as if the objects have to be as distinct as an apple is from a banana is from a mangoe. I might use this example instead: Class --> Fruit Subclasses --> Apple, Banana, Mango Objects --> apple1, apple2, apple3 good_banana, bad_banana, the_only_mango More on reddit.com

What is the purpose of declaring a Hashmap with params on both sides vs one side?

The first one is using type inference . See the section labeled "Type Inference and Instantiation of Generic Classes" for specific details on this kind of type inference. The point is, they are both the same thing. The second one is the more traditional way to write it, and was the only correct way to write it before type inference was added to Java. But the first one is the way to write the same thing with less total code. In the end, both of the map variables would be HashMap variables; the first way is just a more efficient way to write it out. More on reddit.com
