Java：InputMismatchException

Question

我有错误：

export class BasketmenuComponent implements OnInit, OnDestroy {
  product : Product;
  subscription : Subscription;

  constructor(private basketdataService: BasketdataService) {
    this.subscription = this.basketdataService.onGetBasket().subscribe(product=> { this.product = product; });
  }
  ngOnInit() {
  }
  ngOnDestroy() {
    // unsubscribe to ensure no memory leaks
    this.subscription.unsubscribe();
  }

我有一个employee和employeetest类...当我运行程序时，在初始化第二个对象时，在姓氏后面有错误。

我无法输入employee2的双“薪水”。

如何解决此问题？
