Hello, I$\text{'}$m trying to code a simple tanks game in java that looks like this. It's basically the tanks game on mathsisfun.com, I$\text{'}$m trying to draw and render the terrain by reading it from a txt file where $"$X$"$ represents the height of the terrain, $"$T$"$ represents trees, and alphabet letters represents the default positions of the player tanks as shown in the photo.

Here's my current code, how do i read the level$1.$txt file and then draw the terrain by reading that file? Each level is read from a text file of characters $28$x$20.$ The size of the window should be $864$x$640,$ meaning each character in the file corresponds to $32$x$32$ pixels. The terrain should comprise of a smooth curve that is formed from computing the moving average of $32$ values twice.

Current code:

I attached a photo of the "level$1.$txt$"$ file that needs to be read and used to draw and render the terrain. Please help.
