Finding a file in derectory 1

[developer155]

What is the easiest way in java to search a given directory for a file. I have a directory and folder path where I have to fina a file, with name like MyFile.GIF. How can I do it with Java

thanks

Hi,

Try this.. it will return you boolean value if the file exists in a directory..

public class DetermineFileDirExists {

private static void doTest() {

// Create a File object
File file1 = new File("README_InputFile.txt"
File file2 = new File("BlaBlaBla.txt"

boolean b = file1.exists();
System.out.println();
System.out.println("Does File/Dir " + file1 + " exist? (" + b + &quot\n"

b = file2.exists();
System.out.println();
System.out.println("Does File/Dir " + file2 + " exist? (" + b + &quot\n"


}
public static void main(String[] args) {
doTest();
}

}

Cheers,
Venu

Venu, but where do you specify the directory? I only see you specify 2 text files. I need to give a directory and a file to search for in that directory

Liek my directory is c:\docs\folder
File name is Picture.GIF

thanks

public boolean find(String dir, String file) {
  File d = new File(dir);
  File[] files = d.listFiles(); 
  for (int i = 0; i < files.length; i++) {
    if (files[i].toString().equals(file)) {
       return true;
    }
  }
  return false;
}

damn TGML is broken :

public boolean find(String dir, String file) {
  File d = new File(dir);
  File[] files = d.listFiles(); 
  for (int j = 0; j < files.length; j++) {
    if (files[j].toString().equals(file)) {
       return true;
    }
  }
  return false;
}

BTW, it oftens helps to read the manual !!!

No.

You need to use java.net.URL and java.net.URLConnection ...
