Java获取磁盘空间的两种代码示例

本文分享了两段获取磁盘空间的代码，参考下。

代码1：

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");System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024*1024) + " GB");System.out.println("Free Space : " + freePartitionSpace / (1024 *1024*1024) + " GB");}}

运行结果

代码2：

public class FreeDiskSpace {public static void main(String[] args) {File file = new File("c:");long totalSpace = file.getTotalSpace();long freeSpace = file.getFreeSpace();long usedSpace = totalSpace - freeSpace;System.out.println("总空间大小 : " + totalSpace / 1024 / 1024 / 1024 + "G");System.out.println("剩余空间大小 : " + freeSpace / 1024 / 1024 / 1024 + "G");System.out.println("已用空间大小 : " + usedSpace / 1024 / 1024 / 1024 + "G");}}

结果：

总结

哈哈，让大家见笑了。
