Finding Java difficult

I'm nearly halfway through the Java course and although I manage to answer most the questions fine, I feel like I still have no idea what I'm doing with the language. Anyone else get this with Java or another language? I feel like a lot of terminology and syntax is taken for granted and goes unexplained.

Sounds like you need practice. Start coding ^^

If you really want to know, tell me what lesson and which quiz from it.

the answer is ten. basicly method change() take p as variable argument. when it is called it can change attribut p.

Mistakes help a lot. Just take one step after another. If you got stuck, search on Google or ask here.

It may be helpful for you to take a look at some simple codes at the playground, too...

Yes, the playground sometimes does this 'no output' thingy :( But if it always does, there may be no output...

Ok, I see. Just remember that methods are called by value. See the notice from lesson 1 in the same chapter.

not sure that'll help because if I'm not understanding why things are the way they are there are only going to be mistakes. Also the coding examples being taught are incredibly dull.

Also, I /did/ copy the text of one of the questions to test how it output because I couldn't work out the answer, and it came back in the playground as 'no output' over and over.

if there is no output, how can they expect us to answer it as part of the lesson?

it was the second question of 'value & reference types' of 'classes & objects'. I got the answer because I kinda guessed, but the previous lesson I feel didn't give enough information to answer it.

What I think I might do is go on a break, and reset progress on Java and start again. That method worked with C++ when I was struggling. Oh my god I just realised why it's called C++... *slaps forehead*

So it just overrides the earlier statement and redefines the variable attribute? Simple as that?
