一个方法里能不能有两次try catch

public int[] insertData() {

System.out.println("要输入几个成绩");

Scanner sc = new Scanner(System.in);

try {

int k = sc.nextInt();

} catch (java.util.InputMismatchException e) {

System.out.println("输入的数据有误，请重新");

sc.next();

}

int[] a = new int[k];

for (int i = 0; i < a.length - 1; i++) {

System.out.print("请输入第" + (i + 1) + "个数据：");

try {

a[i] = sc.nextInt();

} catch (java.util.InputMismatchException e) {

System.out.println("输入的数据有误，请重新");

sc.next();

continue;

}

}

return

a;

}
