Sorting elements of a Collection

                         

This section gives you the best illustration for sorting elements of a Collection. You can see how to sort all elements of a Collection in ascending or descending order.

In this section, the given program sorts all the elements of a Collection in ascending order. If your text starts with the Upper case letter then the text comes first that mean the uppercase letter is less priority than lowercase letter.

Code Description:

This program creates an string type array and takes some text as input from the user for the created array. Array with elements are assigned to the List (Collection) and then all the elements of the list are arranged in the ascending order.

Collections.sort(list):
Above method sorts all the elements of the specified Collection. List name which elements have to be sorted is passed through the method as a parameter. This method sorts elements in ascending order by default.

Here is the code of the program:

import java.util.*;
import java.io.*;

public class SortingCollection{
  public static void main(String[] argsthrows IOException{
    int n = 0;
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    System.out.print("How many elements you want to enter in the list : ");
    try{
      n = Integer.parseInt(in.readLine());
    }
    catch(NumberFormatException ne){
      System.out.println(ne.getMessage() " is not a legal entry.");
      System.out.println("Please enter a numeric value.");
      System.exit(1);
    }
    String[] names = new String[n];
    System.out.println("Please enter some names : ");
    for(int i = 0; i < n; i++){
      names[i= in.readLine();
    }

    List<String> list = Arrays.asList(names);
    Collections.sort(list);
    System.out.print("Elements of the list in sorted order : " + list);
  }
}
