我在这种类型中遇到了一些麻烦。它只会按顺序正确显示第一个文件。任何人看到我做错了什么?我一直试图找出几个小时,只是没有看到我做错了什么。选择用对象ArrayList排序
public void sort() {
int i; //loop control
int last; //last position in the arraylist
int max; //position where last alphabetical filename is found
max = 0; //largest position so far is first, since i haven't checked
//I thought i should start at the end and work my way down
for(last = fileList.size()-1; last >= 0; last--) {
for(i = 0; i < fileList.size(); i++) {
if(fileList.get(max).getFileName().compareTo(fileList.get(i).getFileName()) > 0)
max = i;
}
//swap pixfile in last position with the last alphabetical
Pixfile tempPix = fileList.get(last);
fileList.set(last, fileList.get(max));
fileList.set(max, tempPix);
//i thought i would repeat until last = 0 and the arraylist is sorted
}//end for
}
调试存在使用。 – 2013-03-21 01:53:38
请张贴一些样本输入和输出。还要更详细地描述问题。你为什么要实现排序而不使用'Collections.sort(fileList);'? – Jess 2013-03-21 01:56:14
