ADF Basics: Reorder ADF table column using DisplayIndex property

This post is about a very simple use case that is reordering of af:table column at run time. 

Ordering of columns in af:table is controlled by DisplayIndex property of af:column
Check what docs says-

Default Value: -1

The display order index of the column. Columns can be re-arranged and they are displayed in the table based on the displayIndex. Columns are sorted based on the displayIndex property, columns without displayIndex are displayed at the end, in the order in which they appear. The displayIndex attribute is honored only for top level columns, since it is not possible to rearrange a child column outside of the parent column.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core

We can set DisplayIndex property for all columns in a sequence (1,2,3 etc) that we want to see on page

Allow user input in Jdeveloper for Java applications, Using Java Scanner Class to take input from console

Sometimes we have to take input from Keyboard when we use Scanner or BufferedReader class.
and to take input from Jdeveloper we have to change a setting to allow user input in Jdeveloper.

Let's take an example of java.util.Scanner class-

package client;

import java.util.Scanner;

public class UserInput {
    public UserInput() {
        super();
    }

    public static void main(String[] args) {
        System.out.println("Please Enter your Name-");
        Scanner sc = new Scanner(System.in);
        String name = sc.next();
        System.out.println("Your Name is " + name);
    }

}
