Well, I'm not going to do your homework for you, but I'll show you how I might accomplish this in the D programming language, and you can adapt it to java:

void main() {
  auto arr = [4, 3, 1];
  int[][] arrays = [];
  foreach (len; arr) {
    arrays ~= new int[len];
  }
}

The homework are much bigger then that, its just a small part which i don't understand how to make, because how can you create 3 new arrays and who is giving them their names?

Anyway thank you for your time...
