You got this error because you are trying to declare your variable after import statements, not into the class.
You should declare it as below:

//import statements
@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"],
})
export class AppComponent {
  category: category[] = [];
  constructor() {}

  ngOnInit() {}
}
