Create an Array of Arraylists

ArrayList[] group = new ArrayList()[4]

But it's not compiling. How can I do this?

As per Oracle Documentation you should follow the below-mentioned code to solve java array of arraylists:

"You cannot create arrays of parameterized types"

Instead, you could do:

  ArrayList> group = new ArrayList>(4);

tackline, it is even better to do:

  List> group = new ArrayList>(4);
