ErrorRecord

代码如下：

import java.util.HashMap;import java.util.LinkedHashMap;import java.util.Scanner;public class ErrorRecord {    public static void main(String[] args) {LinkedHashMap<String,Integer> map = new LinkedHashMap<String,Integer>();String[] record = new String[8];Scanner scan = new Scanner(System.in); int count = 0;String str = null;while(scan.hasNext()){str = scan.next();int index = str.lastIndexOf('\\');str = str.substring(index + 1);if(str.length() > 16){str = str.substring(str.length() - 16, str.length());// substring(a,b)不包括下标为b的字符}String left = str+" " + scan.nextInt();if(map.containsKey(left)){int value = map.get(left);map.put(left, value+1);}else{record[count%8] = left; map.put(left, 1);count++;}}for(int i=count%8;i<8;i++){if(record[i]!=null){int time = map.get(record[i]);System.out.println(record[i]+" "+time);}}for(int i=0;i<count%8;i++){if(record[i]!=null){int time = map.get(record[i]);System.out.println(record[i]+" "+time);}}scan.close();}}
