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。
