取得硬盘剩余空间的Java代码

import java.io.File;
 
public class DiskSpaceDetail {
 
    public static void main(String[] args) {
 
        File diskPartition = new File("C:");
 
        long totalCapacity = diskPartition.getTotalSpace(); 
 
        long freePartitionSpace = diskPartition.getFreeSpace(); 
        long usablePatitionSpace = diskPartition.getUsableSpace(); 
 
        System.out.println("**** Sizes in Mega Bytes ****\n");
 
        System.out.println("Total C partition size : " + totalCapacity / (1024*1024) + " MB");
        System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024) + " MB");
        System.out.println("Free Space : " + freePartitionSpace / (1024 *1024) + " MB");
 
        System.out.println("\n**** Sizes in Giga Bytes ****\n");
 
        System.out.println("Total C partition size : " + totalCapacity / (1024*1024*1024) + " GB");
