java - Changing the variable assigned everytime a loop iterates -

i trying build program allows user enter length , width of object many times choose (i build more code choose how many times loop goes). having problems figuring out how input , construct object every time loop iterates. thanks!

public static void main(string[] args)  {     scanner console = new scanner(system.in);      (int = 1; <= 2; i++)     {         system.out.println("enter length" + + ": ");         int length = console.nextint();          system.out.println("enter length" + + ": ");         int width = console.nextint();          object instance1 = new object(length1, width1);     }   } 

you can use arraylist/linklist, if entries big go linklist.

scanner console = new scanner(system.in); system.out.println("enter how many records want: "); int j = console.nextint(); //"loop run "+ j +" times" list<objectname> objectlist = new arraylist<objectname>(); int length = 0; int width = 0;  (int = 1; <= j; i++) {   system.out.println("enter length" + + ": ");   length = console.nextint();   system.out.println("enter width" + + ": ");   width = console.nextint();   objectname instance1 = new objectname(length, width);   objectlist.add(instance1); }
