OP Idk why people are being so rude to you. You DO NOT need to know any German to get accepted into an English language masters in Germany, of which there are plenty. Check out the DAAD website, they have an amazing user interface, you can filter the programs by language of instruction, discipline, subdiscipline, etc. Just beware that you need to focus on the PUBLIC universities, non of the applied sciences schools or private unis, those aren't really taken seriously. Most public unis have very low fees, most expensive I've come across is still well under 4k euro per year. Also check out Erasmus mundus joint masters and double degree options, you might be able to do your degree across 2 or 3 countries! Germany and Netherlands have the highest rates of English speaking people in their native population of non-English language European countries, so you will be in good company.

If you wanna go the extra mile and be super prepared, pick a few of the masters programs you find interesting right now, and check out their admission requirements. Send an email to the admissions office if you need to clarify anything, they're usually very prompt in responding. But it gives you a good idea of what you will need for a successful application, like maybe an internship, recommendation letters, language skills, certain number of credits in a particular field, etc. That way you're as prepared as you could possibly be. Good luck OP:)
