我希望搜索给定目录中的所有文件/文件夹,直到某个深度。到目前为止,这是我的代码
import java.io.File;
import java.util.Scanner;
/*
* Michael Woloski - Program Three
*
* This program allows the user to enter a desired path
* then the program will display every file or directory
* within the specified path. The user will also enter a
* desired depth, so if the path contains multiple
* directories, it will display the files/folders in the sub
* directory
*/
public class MainClass {
static Scanner sc = new Scanner(System.in);
public static void fileListingMethod( File [] files, int depth )
{
if( depth == 0 )
{
return;
}
else
{
for( File file : files )
{
if( file.isDirectory() )
{
System.out.printf( "Parent: %s\n", file.getParent() );
System.out.printf( " Directory: %s\n", file.getName() );
fileListingMethod( file.listFiles(), depth-- );
}
else
{
System.out.printf( " File: %s\n", file.getName() );
}
}
}
}
public static void main( String [] args )
{
System.out.printf("Please Enter a Desired Directory: ");
String g_input = sc.nextLine();
if( new File( g_input ).isDirectory() )
{
System.out.printf( "Please Enter Desired Depth: " );
int depth = sc.nextInt();
File [] file = new File( g_input ).listFiles();
fileListingMethod( file, depth );
}
else
{
System.out.printf( "The path %s is not a valid entry. Exiting. ", g_input );
System.exit( 0 );
}
}
}
但是,如果用户输入3作为深度,则会扫描目录中前三个文件夹中的所有文件夹/文件。
基本上,我希望将文件/文件夹从一个目录中提取到所需的深度。
答案 0 :(得分:0)
你正在改变递归呼叫的深度;你应该只使用depth-1(给出你想要的值而不改变它)。
