Java尝试catch for do while loop

Question

我在尝试为do while循环执行try catch时遇到了一些问题：

try{
    do {
        System.out.println("Enter your option: ");
        choice = sc.nextInt();
        switch (choice) {
            case 1:
                break;
            case 2:
                break;
            case 3:
                break;
            case 4:
                break;
            case 5:
                break;

        }
    } while (choice != 6);
    }catch(InputMismatchException e){
        System.out.println("Please enter option between 1-6.");
    }

Answer 1

喜欢：

try {
   choice = sc.nextInt();
} catch(InputMismatchException e){
        System.out.println("Please enter option between 1-6.");
        sc.next();
        continue;
    }

如果用户输入了无效的输入，它将转到catch块并继续循环。移除外部的try catch块。不需要
