Android - For loop not incrementing integer

I have a for loop which allows me to work out a level of a player, however the level doesn't get incremented after each loop, heres my code:

int[] Level_XP = new int[] {0,Level1, Level2, Level3, Level4, Level5, Level6, Level7, Level8, Level9, Level10, 
          Level11, Level12, Level13,Level14, Level15, Level16, Level17, Level18, Level19, Level20, 
          Level21, Level22, Level23, Level24,   Level25, Level26, Level27, Level28, Level29, Level30,
          Level31, Level32, Level33, Level34, Level35, Level36, Level37,    Level38, Level39,Level40, 
          Level41, Level42, Level43, Level44, Level45, Level46, Level47, Level48, Level49, Level50};

int level;
for (level = 1; User_XP < Level_XP[level];level++) { }
Minimum_Percentage = Level_XP[level];
Maximum_Percentage = Level_XP[level+1];
User_Level.setText(Integer.toString(level));

I have intialised all the integers and there is an array being used, can anyone help me to actually increase the level after each loop? As this way the level only stays at level 1.

int level ;
for (level = 1; User_XP < Level_XP[level];level++) { }
Minimum_Percentage = Level_XP[level];
Maximum_Percentage = Level_XP[level+1];
User_Level.setText(Integer.toString(level));

There are quite a few problems with the above statements, even some code goes in the for loop.

  1. What if User_XP < Level_XP[level]; is always true ? You pass the array length and an exception is generated.

  2. If condition satisfied for the very last element of the Level_XP in for loop, then

    Maximum_Percentage = Level_XP[level+1]; // This causes exception

Your for-loop is empty. That's why nothing happens there.

for (level = 1; User_XP < Level_XP[level];level++) { }

You didn't write anything in the curly braces. So your loop will be empty.
