If I quite understood your question, and I think nobody can (Explain)
if (file.getName().indexOf("hallo") != -1) {
//Your code here
}

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:


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

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 ;
}
}) ;
}
