I want to know how to input/output a large number file

We're going to practice creating more than 100,000 random natural numbers with 2³² in java I don't think it's possible with a scanner. It's not working. I'm trying to create it, save it, load it, and sort it out I don't know how to use it.

I'm going to make random and long ones, too It doesn't work well because it's mixed with negative numbers Please help me with what I should write
