Random numbers and arrays

[caro]

Hi,
I'm new to writing java and am having a bit of trouble writing a program and would really appreciate some help :)
Im trying to make a program that creates an array of 20 random integers between 0 and 99, then allows the user to enter a number (N) between 0 and 99 so that it (the program) can tell the user how many of the integers are greater than or equal to N.
Everything i've tried gets an error! please help! :o

you can post your code, it will be helpfull otherwise check this example:Generate random numbers using Math.random | Java Examples - Java Program Sample Source Code

... moving to "New to Java" subforum since no reference to NetBeans can be observed.

Here's some pseudo code that might help:

• create array (size 20)
• Ask user for number between 0 & 99
• start loop (20 loops)
• create random number between 0 & 99 (Using Random class)
• insert random number as an element into the array
• end loop
• start loop (size 20)
• if array element >= user's number then add 1 to "greaterEqual" variable
• end loop
• print "greaterEqual" variable

... or somethng like that

Luck,

Check out the Random class or the Math.random() method for generating the random numbers.

Also check out Arrays.

If your unsure as to how to make the loops, conditional statements, and flow of the program as well, it's probably best you start from the beginning.
