如何在Java目录中对文件进行排序？

Arrays.sort( files, new Comparator<File>() {    public int compare( File a, File b ) {        // do your comparison here returning -1 if a is before b, 0 if same, 1 if a is after b    }} );

您可以定义许多不同的

Comparator

public class FileNameComparator implements Comparator<File> {    public int compare( File a, File b ) {        return a.getName().compareTo( b.getName() );    }}public class FileSizeComparator implements Comparator<File> {    public int compare( File a, File b ) {        int aSize = a.getSize();        int bSize = b.getSize();        if ( aSize == bSize ) { return 0;        }        else { return Integer.compare(aSize, bSize);        }    }}...

然后，您只需将它们换出：

Arrays.sort( files, new FileNameComparator() );

要么

Arrays.sort( files, new FileSizeComparator() );
