Java中的 FileStore getTotalSpace() 方法及示例

FileStore类的getTotalSpace()方法用于返回文件存储的总大小,以字节为单位。此方法将此总大小作为长值返回。

句法:

public abstract long getTotalSpace()
                throws IOException

参数:此方法不接受任何内容。

返回值:此方法将文件存储的总大小作为长值返回。

异常:如果发生 I/O 错误,此方法将抛出IOException

下面的程序说明了 getTotalSpace() 方法:

方案一:

// Java program to demonstrate
// FileStore.getTotalSpace() method
  
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create the object of Path
        Path path
            = Paths.get(
                "E:\\Tutorials\\file.txt");
  
        // get FileStore object
        try {
  
            FileStore fs
                = Files.getFileStore(path);
  
            // print FileStore name and Total size
            System.out.println("FileStore Name: "
                               + fs.name());
            System.out.println("FileStore TotalSpace: "
                               + fs.getTotalSpace());
        }
        catch (IOException e) {
  
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

输出:

方案二:

// Java program to demonstrate
// FileStore.getTotalSpace() method
  
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create the object of Path
        Path path
            = Paths.get(
                "C:\\Movies\\001.txt");
  
        // get FileStore object
        try {
  
            FileStore fs
                = Files.getFileStore(path);
  
            // print FileStore name and Total size
            System.out.println("FileStore Name: "
                               + fs.name());
            System.out.println("FileStore TotalSpace: "
                               + fs.getTotalSpace());
        }
        catch (IOException e) {
  
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
