    Unhappy Trying to read a directory recursively and match a String with the files present and return the file names matching the String.

    I was doing a program that searches a directory recursively and matches a String "Claims" with the file names.
    If the files are found with name starting from Claims they shall be shown in the output.
    I am posting my code below.

    import java.io.File;

    public class FileSearchRecursively {
    public static void main(String[] args){
    FileSearchRecursively f=new FileSearchRecursively();
    f.listFile("D:/Abhishek/src", "Claims" );
    }

    public void listFile(String pathname,String searchKey) {
    File f = new File(pathname);
    File[] listfiles = f.listFiles();
    for (int i = 0; i < listfiles.length; i++) {
    if (listfiles[i].isDirectory()) {
    File[] internalFile = listfiles[i].listFiles();
    for (int j = 0; j < internalFile.length; j++) {
    String val=internalFile[j].getAbsolutePath();
    if (internalFile[j].isDirectory()) {
    String name = internalFile[j].getAbsolutePath();
    listFile(name,searchKey);
    }else
    {
    if(val.equals(searchKey));
    }
    }
    }
    else {
    System.out.println(listfiles[i]);
    }

    }

    }
    }

    Wrap your code in code tags. Do you have a question, or is that just an example for fragile code?

    I have given my code.
    Its just traversing all the files but not returning the files that matches with the string "Claims".
    Can you help me with that only. what modifications are needed to acheive the required output?

    I have no idea what the required output should be, I have no idea what you currently get and you've never asked a question.
