I don't have any idea what Ready To Program means but here's how to generate a random integer between 0 and 100:
Integer i;
java.util.Random rand = new java.util.Random();
i = rand.nextInt(101);
Now, if you were to put the "i = rand.nextInt(101);" line inside a loop that iterates 40 times, you would generate 40 random numbers between 0 and 100. Of course, if you want to see the list, you'll need to print it out. Adding a call to one of java's print or println methods after the "i = ..." line, inside your "1 to 40" loop, you'd get your list.

I am not sure what "Ready To Program" is, but try something like this:
Random rd = new Random(187654329);
List<Integer> numbers = new ArrayList<Integer>();
for (int a = 0; a < 40; a++) {
int num = rd.nextInt(101);
//optional output
//System.out.println(num);
numbers.add(num);
}

the two one among those suggestions are incorrect yet shadowman's blunders is minor the nextInt(a hundred and one) will return values from 0 by way of a hundred, inclusive. What you rather need is: nextInt(a hundred) + a million which provides you with values from a million by way of a hundred, inclusive.
