That's exactly what CJ showed you. The indexOf method looks for a piece of a string and returns -1 if the search string does not contain it.

This is exactly what your looking for:

Code:

---

if (file.getName().indexOf("hallo") != -1) {
      //Your code here
    }

Which is what he posted.

thank you very much but when i creat file like
flie f=new file("c:/................")
and write
file.getname();
it give me the last name of file in path and that isnot what i want
say that the path is c:/document............./input
and i want to make search on the files that input folder have
acoording to certain part of name

Code:

---

  public static void main (String args[]) {
    File f = new File("C:/") ;
    f.list(new FilenameFilter()
    {
      public boolean accept (File dir, String name) {
        return name.indexOf("hallo") != -1 ;
      }
    }) ;
  }
