    Default Printing random values from array list.

    Hello guys,
    I am having a hard time trying to figure out how to print random numbers from a an array list. I tried google but nothing worked. I have to pick certain values from two lists and print them on the screen. I have included comments in the code to facilitate the explanation. Thank very much in advance.


    This is my code:

     
     
     
    import java.util.Random;
    public class Parachute {
     
     
    	public static void main(String[] args) {
    		Random randomNumbers=new Random();
    int number;		
     
     
     
    int array []={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21};
    char A[] = {'a', 'b', 'c','d','e','f','g','h', 'i','j','k','l','m','n','o','p','q'}; 
     
    number = 5 + randomNumbers.nextInt(2);
     
    if ( number==5 )
     
    {
    	number=1+randomNumbers.nextInt(3);
     
    	if (number==1)////pick and print 3 random letters from char and pick and print one random number
    	{System.out.println("3 random letters and one random number");}
     
    	if (number==2)///pick and print 2 random numbers and 1 random letter from char
    	{System.out.println("2 random numbers and one randon letter");}
     
    	if (number==3)///pick 5 random letters
    	{System.out.println("5 random letters " );}
     
    }
     
    if (number==6)// pick and print 5 random letters
    {System.out.println(" 5 random letters");}
    	}
     
    }
