我在java中执行我的代码但是我每次都会收到数字异常错误。请帮忙
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:
线程中的异常&#34; main&#34; java.lang.NumberFormatException:用于输入 string:&#34; 3 2&#34;在 java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) 在java.lang.Integer.parseInt(Integer.java:580)at java.lang.Integer.parseInt(Integer.java:615)at TestClass.main(Main.java:14)
答案 0 :(得分:0)
尝试使用拆分方法:
而不是:
StringTokenizer stk = new StringTokenizer(input);
int n = Integer.parseInt(stk.nextToken());
int q = Integer.parseInt(stk.nextToken());
使用:
[] = input.split中的字符串(&#34;&#34;);
int n = Integer.parseInt(在[0]中);
int q = Integer.parseInt(在[1]中);
