PAT 乙级 1058 选择题(20) Java版

由于之前此题java超时，最后曲线救国，刷了无数题之后，找到了一个java快速io

源码先贴出来 已ac

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.StreamTokenizer;

public class Main {

static StreamTokenizer in = new StreamTokenizer(new BufferedReader(new InputStreamReader(System.in)));
static int nextInt() throws IOException{in.nextToken(); return (int) in.nval;}
static String next() throws IOException{in.nextToken(); return in.sval;}

public static void main(String[] args) throws IOException {
int gradePb[], gradePs = 0, n, m, wrongCnt[];
int maxCnt = 0;
String str, ansStr[];
StringBuilder sb = new StringBuilder();
char ch;
n = nextInt();
m = nextInt();
gradePb = new int[m];
wrongCnt = new int[m];
ansStr = new  String[m];

int a, b, c, ttemp;
for(int i = 0; i < m; i++)
{
a = nextInt();
b = nextInt();
c = nextInt();
ttemp = c;
sb.append(c);
while(ttemp-- > 0)
{
str = next();
sb.append(str);
}
ansStr[i] = sb.toString();
gradePb[i] = a;
sb.delete(0, sb.length());

}
for(int i = 0; i < n; i++)

System.out.println(gradePs);

System.out.print(maxCnt);
