Help Time Convert From Unix To Java

[Pleyne]

Basically i want to convert UNIX timestamp to Java date in format this format "dd.mm.year hour-1 :: hour+1".
I tried to make it on my own, but it seems for a newbie like me is to hard, could someone give a quick tip/guide? Thank you in advance.

Edit: i CAN make it happen, but the code itself is very shitty, after taking -1 hour (for example it's 00:00, so -1 will make 23:00, but in my case it makes 0-1:00 :( ) and tone of appends
