The main locations in Minecraft are nether Fortresses, a mine, I prefer to find a ravine since a lot of ores are exposed, a lava pool, and a water pool, and of course the end, you will need diamond gear to fight the ender dragon, and to get into the end you have to find the stronghold, but before that you have to find enderpearls, you can sometimes find some in the stronghold but never enough to fill the portal so you will have to go out and kill some endermen which can be found more often in the nether and they, have a high percentage about %89 chance of dropping ender pearls, then you need to kill blaze's, which are in the end and spawn on nether fortresses, they have a %76 percent chance of dropping blaze rods which is what you'll need, once you have them put them in your crafting UI in your inventory in one corner which will make blaze powder, then combine the blaze powder and the enderpearls in 2 corners in your inventory and you will get eyes of ender then go back to the overworld and right click with the eye of ender and keep following it once it goes at an angle straight towards the ground then dig where it landed and keep digging and when you see mossy stone bricks dig through them and you'll be in the stronghold then place your eyes of ender on the end portal frame and then jump in, fight the ender dragon and...., you've beat the game! this is the important locations and how to beat the game in Minecraft Java Edition, and Minecraft Java Edition Demo, They are both the same except in the demo you don't have all privileges as in the original, such as commands, creative, multiplayer, etc.
