I want to write a java code that will
1. go a path (eg: C:/dev/myxmls)
2. pick one by one all files (all are having *.xml extension) from 'myxmls' folder
3. print that file name on console (System.out.printly(filename))

We would much rather see you post your own code, working or not, and give you tips to help you get it working or point you toward resources that will help you to learn how to solve your problem using best practices.



show us the code you have so far so that we can advise on it.

And the question is...?

You seem to have a pretty good idea of what steps are necessary to accomplish your task. Implement them exactly in the order you've listed them, and if you encounter a problem then post an actual question and your code. That way, you might get answer.

Edit: No such thing as System.out.printly in Java.

public static void main(String[] args) throws IOException {
String file ="C:/dev/myXMLs";
File[] f = finder(file);

while(f!=null){
System.out.println(f[0].getName());
BufferedWriter out = new BufferedWriter(new FileWriter("C:/dev/abcd.txt"));
out.write(f[0].getName());
out.close();
}
}
public static File[] finder( String dirName){
File dir = new File(dirName);
return dir.listFiles(new FilenameFilter() {
public boolean accept(File dir, String filename){
return filename.endsWith(".xml"); }
} );
}

This goes into infinite loop.

Please put your code inside code tags.

Your f array contains files (supposing your method works well). So, basically, it's never null so your while loop never ends.
Why not try different approach? Since you're working with array, for loop seems like a better solution.
