Java使用apache commons io获得磁盘的剩余空间详解编程语言

使用apache commons io包中的FileSystemUtils和FileUtils类获得磁盘剩余空间：

import 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(); 
        } 
    } 
}
