Free Minecraft

Look. I really don’t have money right now. I just bought my little brother a pc of his own. And he wants me to play Minecraft with him but I can’t because I don’t have it. I used to own it on my Xbox but I don’t have my Xbox anymore. Does anyone know a way I could acquire mc for Java free so I can play with my brother? I definitely don’t stand for piracy so don’t suggest it. Thanks guys. Have an amazing day
