Yes, to modify the datatype of the `array` variable in module `top` according to REQ-EXT-10007, you should change its datatype from `integer` to `int`.

Here is the modified code:

interface Int();
  class t1;
    int a[string];  //REQ-EXT-10007
    function new;  //class constructor body need be modified according to REQ-EXT-10007
      a["a"] = 40;
      a["b"] = 60;
      a["c"] = 80;
    endfunction
  endclass
  
  class t2;
    int b[string];  //REQ-EXT-10007
    function new;  //class constructor body need be modified according to REQ-EXT-10007
      b["aa"] = 44;
      b["bb"] = 66;
      b["cc"] = 88;
    endfunction
  endclass
  
  t1 inst1 = new; //REQ-EXT-10501
  t2 inst2 = new;  //REQ-EXT-10501
endinterface

module top;
  Int in();
  virtual Int testint = in;
  int array[string]; //data type of array need be modified according to REQ-EXT-10007
  initial begin
    #1;
    array = testint.inst1.a;
    $display("testint.inst1.a = %p", testint.inst1.a); //CHECK-001:'{"a":40, "b":60, "c":80}
    $display("array = %p", array); //CHECK-002:'{"a":40, "b":60, "c":80}
    #2;
    array = testint.inst2.b;
    $display("testint.inst2.b = %p", testint.inst2.b); //CHECK-003:'{"aa":44, "bb":66,"cc":88}
    $display("array = %p", array); //CHECK-004:'{"aa":44, "bb":66,"cc":88}
  end
endmodule

Note that I have replaced the `integer` datatype with `int` in both the `t1` and `t2` classes as well as in the `array` variable declaration in module `top`.
