how to?

I have to let the user press in a number, and the number that is being inserted is the amount that the program has to run.

so i have this already

System.out.println("How many simulations do you want");
numberSimulations = Input.readLong();

for ( y = 0 ; y = numberSimulation ; y ++) {
SimulationThatHasToBeDoneXNumberOfTimes();

this way doesn't work because it has to be boolean,can anyone tell me another way of doing this??

y = numberSimulation

A single equals is assignment. A double equals is comparison. Do you really want the loop to execute ONLY when y equals numberSimulation?

if the input is 100, the loop has to be done 100 times but i don't think for is the right way.
i have to run SimulationThatHasToBeDoneXNumberOfTimes(); an amount of times==>that amount is chosen by the user(input)

I understand, I want you to think about it. If numberSimulation is 100 and y is 0 what should the condition of your loop be?

y <= number

thank you very much
