Java FileStore getTotalSpace()用法及代码示例


FileStore类的getTotalSpace()方法用于返回文件存储的总大小(以字节为单位)。此方法以long值形式返回总大小。

用法:

public abstract long getTotalSpace()
                throws IOException

参数:此方法不接受任何内容。


返回值:此方法以long值形式返回文件存储的总大小。

异常:如果发生I /O错误,则此方法将引发IOException。

以下示例程序旨在说明getTotalSpace()方法:

示例1:

// 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:
