As Oromus said, that example is in C++. All you're doing is calling a function -- inside the Compressor object there is a function called setClosedLoopControl that takes a boolean as an argument. In Java, that would be articulated as...

c.setClosedLoopControl(true);

...while in C++ that would be:

c->SetClosedLoopControl(true);

They both do the same thing; they're just differences between languages. It's like comparing apples to oranges -- they both can achieve the same thing (making you less hungry) but the means of doing so is relatively different.

that was a horrible example imsosorry
