Hi Friend,

Try the following code:

import java.util.*;
import java.io.*;
public class City{
public static void main(String[]args)throws IOException{
int count = 0;

String arr[] = new String [4];
File f=new File("test.dat");
BufferedReader br = new BufferedReader(new FileReader("test.dat"));
int i;
setArray(arr,br);
for( i = 0; i < arr.length; i++){
System.out.println(arr[i]);
}
Arrays.sort(arr);
System.out.println("Sorted Array= "+Arrays.toString(arr));

Arrays.sort(arr, Collections.reverseOrder());
System.out.print("Sorted Array in reverse order= "+Arrays.toString(arr));
br.close();
}
public static int setArray(String [] arr,BufferedReader br)throws IOException{
int count = 0;
String inputLine = inputLine(br);
while(inputLine != null){
arr[count] = inputLine;

count++;
inputLine = inputLine(br);
}
return count;
}
public static String inputLine(BufferedReader br)throws IOException{
String inputLine = br.readLine();
return inputLine;
}
}
Hope that it will be helpful for you.

Thanks
