  @goldey --

  You can do this:

  int a;
  int b;
  int c;
  a = 2;
  b = 4;
  c = 6;
  println(a,b,c);
  

  or:

  int a, b, c;
  a = b = c = 6;
  println(a,b,c);
  

  or:

  int a=2, b=4, c=6;
  println(a,b,c);
  

  ...and the you end up with three declared and assigned variables using any approach.

  However, if you mix types:

  int a;
  int b;
  String c;
  

  ...you cannot declare or assign then together with commas:

  int a, b, String c; // WRONG
  int a=2, b=4, c="x"; // WRONG
