I am starting a Java programming class and they recommend the Head First Java book. After buying the book and going through the instruction for installing the Java SDK, it reads, "if you have a Mac then you don't need to do anything, the Java SDK is already on your machine." The next few bullet points go on to discuss API documentation, setting the PATH, and so on. Are these steps only for Windows installation or do I need to worry about them if I am using a Mac? Can anyone help me with this, and please don't attach a link to the Oracle page and tell me to follow the instructions, because the Oracle page is cluttered with so much information it just frustrates me. Some actual instructions for Mac users would be helpful. Thank you in advance.
