我在按名称排序文件时遇到了一些问题。
Number of records: 2048出现在Number of records: 512
File Set 10.txt:来自File Set 1.txt:
当我运行我的代码时，我得到了这个输出：

这是我的代码：
boolean runTest(String[] text, int[] number, String url, String out, Sort sort) {
PrintWriter filename;
boolean tobeReturned = true;
String beforeSorting = "";
String afterSorting = "";
long startTime;
double timeTaken;
try{
filename = createWriter(out);
File dir = new File(url);
File[] listDir = dir.listFiles();
Arrays.sort(listDir);
for(File directory : listDir){
File[] listOfFiles = directory.listFiles();
Arrays.sort(listOfFiles);
filename.println("Number of Records: \t" + directory.getName());
for (File file : listOfFiles) {
//println(file.getName());
text = loadStrings(file);
number = int(text);
if(isSorted(number)){beforeSorting = "Sorted";}else{beforeSorting = "NOT Sorted";};
startTime = startTime();
sort.sortInteger(number);
timeTaken = stopTime(startTime);
if(isSorted(number)){afterSorting = "Sorted";}else{afterSorting = "NOT Sorted";};
//filename.println("File Set " + file.getName() + ": \t\t" + stopTime(startTime()));
filename.println("File Set " + file.getName() + ": \t\t" + beforeSorting + ": \t" + afterSorting + ": \t" + timeTaken);
timeTaken = 0;
}
filename.println("\n");
}
filename.flush();
filename.close();
} catch (Exception e) {
tobeReturned = false;
}
return tobeReturned;
}
答案 0 :(得分：3)
您的文件按字典顺序排序。如果要按数字顺序对它们进行排序，则必须提供自定义比较器，您应该在其中解析文件名，提取数字部分并按此数字部分进行比较
get答案 1 :(得分：1)
您需要实现自己的比较器，根据整数部分比较文件名。
Arrays.sort(listDir, new Comparator<File>() {
@Override
public int compare(File o1, File o2) {
int num1 = Integer.parseInt(o1.getName().split("\\.")[0]);
int num2 = Integer.parseInt(o2.getName().split("\\.")[0]);
return num1 - num2;
}
});
