hi,
i m very new in java. right now i m facing one problem to read many files from one folder. suppose i have few txt files in one folder and every txt files contain some my friends name.

my program should open that folder and read all files one by one to find all friends name.

so far i have done it from one particular txt file but i cant make it from many files within a folder.

can anybody pls help me.....
1st code that i used to find from one particular file

FileReader fr;			BufferedReader br;
String result="";
String word= new String();
String target = "friend";


try{ //read one text file 
fr = new FileReader ("C:/Users/user/test/new1.txt");
br = new BufferedReader(fr);
Scanner scan = new Scanner(br); 

while(scan.hasNext()){  scan.next();
result = scan.findWithinHorizon(target,0); 

if(result!=null) {
word = (scan.next() + scan.findWithinHorizon("", 0));
    
  ArrayList<String> names = new ArrayList<String>();
names.add(word);
for (int i=0; i< names.size() ; i++) {
System.out.println(names.get(i));}

2nd code where i m trying for many files, it has no errors but no output.

try{ //read files from folder 
File directory = new File("C:/Users/user/test");
String filename[] = directory.list();
	   
		 for (int i = 0; i < filename.length; i++) {
	
reader = new FileReader (filename[i])	;		
br = new BufferedReader(reader);
Scanner scan = new Scanner(reader); 

while(scan.hasNext()){  scan.next();
result = scan.findWithinHorizon(target,0); 

if(result!=null) {
word = (scan.next() + scan.findWithinHorizon("", 0));
  System.out.println(word);
    }
 
  }
 scan.close();
 }
}
catch(Exception e){ System.err.println(e.getMessage()); 
}

Comparing your code snippets maybe you need to use br instead reader in:
Scanner scan = new Scanner(reader);
