Creating and checking directories with java code

[tim]

Hello everyone.

Can someone please give me an example of code so that I can:

1. check if an existing directory exists
2. create a new directory

Any help would be great.

Thank you. :D

		File file = new File("directory path");
		if(file.exists()){
			System.out.println("File Exists");
		}else{
			boolean wasDirecotyMade = file.mkdirs();
			if(wasDirecotyMade)System.out.println("Direcoty Created");
			else System.out.println("Sorry could not create directory");
		}

One more thing .. check java documentation for mkdir() and mkdirs() .. they are different and better if you could find that yourself...
hope it helps ..

Hi,
I want to build a java code that can retrieve the Author name of a .doc/.xls file and then it make a folder with the same name of the Author and copies the file into the folder.

Can anybody give me a suggestion?

Hi there

Is possible to retreive the Author name from any file (.doc/.ppt/.xls etc.)?
Is there any java code that can help me to get author of a file?

Please help me?

Here you go, I have more file operations but you can do it some more simpler... Just check it out.


public class TestMaruti implements FilenameFilter {



int iCount = 0;

public String str1 = null;

public void process(String Filter,String FilePath) throws Exception

{


str1=Filter;

File file = new File(FilePath);

String [] str = file.list(this);

File file1 = new File(FilePath+"/"+Filter);

if(!file1.isDirectory())

{

System.out.println(iCount++);

file1.mkdir();

for(int i=0;i<str.length;i++)

{

System.out.println("Writing the file "+str[i]+"....");

File file2 = new File(FilePath+"/"+str[i]);

File file3 = new File(FilePath+"/"+Filter+"/"+str[i]);

moveFiles(file2,file3);

System.out.println("Completed");

}

}


//file.mkdir();

}


public boolean accept(File dir,String s)

{

if(s.startsWith(str1))

{

return true;

}

else

{

return false;

}

}


public static void main (String args[]) throws Exception

{

String path="D:/Maruti/Test";

TestMaruti tm = new TestMaruti();

File allFiles = new File(path);

String [] strFiles = allFiles.list();

for(int j=0;j<strFiles.length;j++)

{

String flName = strFiles[j];

flName=flName.substring(0,flName.indexOf("."));

tm.process(flName,path);

}

}


public void moveFiles(File source,File destination) throws Exception

{

InputStream in = new FileInputStream(source);

OutputStream out = new FileOutputStream(destination);

byte [] buf = new byte[4096];

int len;

while((len=in.read(buf)) > 0 )

{

out.write(buf,0,len);

}

in.close();

out.close();

source.delete();

}

}



Please let me know incase of questions.

            POIDocument document = new HWPFDocument(new FileInputStream("a.doc"));
            System.out.println(document.getSummaryInformation().getAuthor());

            POIDocument workbook = new HSSFWorkbook(new FileInputStream("a.xls"));
            System.out.println(workbook.getSummaryInformation().getAuthor());

            POIDocument show = new HSLFSlideShow(new FileInputStream("a.ppt"));
            System.out.println(show.getSummaryInformation().getAuthor());

HPSF HOW-TO

It works - please Download Apache POI and put in class path before executing above code.
