At line 9;
An array has elements ranging from 0 up to size-1, you can't start at 1 there and end with 10+1

yes remove it, start at 0 and make the condition less than 10

after that you need to change a few counters with your bubble sort to make it work

int[] sortedArray = bubbleSort(points);

This function must be outside the for loop, that means you call the function only after you are done entering all the numbers.

EDIT : Post whatever errors/exceptions you are getting now

use

import javax.swing.*;

to use JOptionPane.

and change

for (int i=1; i<=10+1;i++)
{ 				
                   points[i]=Integer.parseInt(JOptionPane.showInputDialog(null,"num["+i+"];"));  			
                   ctr = ctr+points[i]+ " "; 			 
                   int[] sortedArray = bubbleSort(points);		 
}

to

for (int i=0; i<10;i++)
{		
		points[i]=Integer.parseInt(JOptionPane.showInputDialog(null,"num["+i+"];"));		
		ctr = ctr+points[i]+ " ";     
		int[] sortedArray = bubbleSort(points);
}
