Java使用apache commons io获得磁盘的剩余空间，apachecommons,使用apachecomm

使用apachecommonsio包中的FileSystemUtils和FileUtils类获得磁盘剩余空间：```javaimport org.apache.commons.io.FileSystemUtils;import org.apache.commons.io.FileUtils;

import java.io.IOException;

public class GetFreeDiskSpace {

public static void main(String[] args) {    try {        // Set a string with the path        String path = "C:";        // Get free space in KB        long freeSpaceInKB = FileSystemUtils.freeSpaceKb(path);        // Calculate free space in GB        long freeSpaceInGB = freeSpaceInKB / FileUtils.ONE_MB;        // Print the result        System.out.println("Free space of " + path + " drive = " + freeSpaceInGB + " GB");    } catch (IOException e) {        e.printStackTrace();    }}

}
