Android - For loop not incrementing integer -

I have a loop for which I am allowed to work at the level of a player, although not increment after level Each loop reads my code:

  int [] Level_XP = new int [] {0, Level 1, Level 2, Level 3, Level 4, Level 5, Level 6 Level 7 Level 8 Level 9 Level 10 Level 11 Level 12 Level 13 Level 14 Level 15 Level 16 Level 21 Level 21 Level Level 22 Level Level 23 Level Level 25 Level Level 26 Level 27 Level 28, Level 29, Level 30, Level 31, Level 32, Level 33, Level 34, Level 35, Level 36, Level 37, Level 38, Level 39, Level 40, Level 41, Level 42, Level 43, Level 44, Level 45, Level 46, Level 47, Level 48, Level 49, Level 50}; Integer level; (Level = 1; user_xp   
 I have intialised all integers and there is an array being used, can someone really help me to increase the level after each loop? In this way the level remains at Level 1 only.   
 
 
 Your for-loop is empty This is why nothing happens. (Level = 1; User_XP   
 You did not write anything in curly braces Your loop will be empty.
