What is a way I can define a range of integers in an if-statement?

When I try to define an integer or attempt to define a range of integers in an if-statement, it returns an error message saying "Unreachable code"

I've tried a few different methods, such as changing the if-statement to

if (rand == 33)

if (rand.nextInt == 33)

which returns the error message "incompatible operand types Random and Int", "nextInt cannot be resolved or is not a field" respectively.

Then I tried

if (rand.nextInt() == 33)

which then spat back "unreachable code".

And for the range issue I tried 33-0, 0-33 which doesnt work.

    public static void main(String args[]){
    System.out.println("Random Integers:"+computeRandom());
}

    public static int computeRandom() {

    //create instance of Random class
    Random rand = new Random();

    //Generate random integers in range 0 to 100

    rand.nextInt(101); //83
    return rand.nextInt();
    if (rand.nextInt() == 33) {

    }

I expect it to eventually return the letter "A" depending on what range it falls under at the moment the range is intended to be 0-33.
