线程“main”java.lang.NumberFormatException中的异常：

Question

class TestClass {
public static void main(String args[]) throws IOException {
  BufferedReader inp = new BufferedReader (new InputStreamReader(System.in));
  String input = inp.readLine();
  //Scanner sc = new Scanner(System.in);
  StringTokenizer stk = new StringTokenizer(input);
  int n = Integer.parseInt(stk.nextToken());
  int q = Integer.parseInt(stk.nextToken());
  int [] arr = new int[n];
  int [] st = new int [n];
  for(int i =0;i<n;i++){
    arr[i] = Integer.parseInt(stk.nextToken());
     st[i] = fib(arr[i]);

  }  
while(q>0){
    int l = Integer.parseInt(stk.nextToken());
    int r = Integer.parseInt(stk.nextToken());
     System.out.println(gcd(st,l,r));
    q--;
}

我不断收到错误消息：

线程“main”java.lang.NumberFormatException.forInputString（NumberFormatException.java:65)在java.lang.Integer.ParseInt（Integer.java:580)在java.lang.Integer.ParseInt（Integer.java:615)在TestClass.Main（Main.java：14）

Answer 1

尝试改用分裂方法：

而不是：

StringTokenizer stk=新StringTokenizer（输入）；
