Thread: While loop question

Could anyone help me figure out why the outer loop stop running after just trial 1? Thanks

        System.out.print("Please enter the number of trials: ");
        int uInput = userInput.nextInt();
 
        for(int counter = 1; counter <= uInput; counter++)
        {
        while(randNum1 != 1)
        {
        randNum1 = randNum.nextInt(5);    
 
        if(randNum1 == 1)
           { 
            wins++;   
            bottleCapNum++;
        }
        else
        bottleCapNum++;
        }
            }

u have in your while loop randNum1 != 1 but you also have if(randNum1 == 1) inside the loop so if that case is true then after that loop randNum1 will be equal to 1 so your while loop will never run again because the condition is now false...

Oh! Thank you for that pointer. Do you have any suggestion on how I can modify my code so that the outer loop will run depending on the user input of trials and the inner loop search until it find the number "1" out of the 0-4 random number that is generated each trials? Then I would need a conditional statement where if the number is 1, the wins++, if it not 1, then bottleCapNum++.

i think i get what ur trying to do... just make the randNum1 generate without the while loop and see if that's what u had in mind... the use of that while loop makes possible for complications and since you're only checking for one condition the if else statement will be all u need really

After the random number is generated, I need to compare it to see if the number is =1, if not the number would have to generate again, for a total of 5 time. Without the while loop, is there another method of doing this ? Thanks

** Better yet, for my while loop, do you know any way I can change the (randNum1 !=1) to something else that does not conflict with the conditionals statement but still have the while loop run until it get 1?

ok i get it you want the number to generate a certain amount of times in the case that the number isn't one and keep count of other variables while that condition is true or not... just reset the randNum1 variable after the while loop so that way when the for loop iterates again the while statement will always be true at least once

May I know how to reset a variable? Thank you.

make it equal 0 after the while loop

Thanks for your help, King.

no prob i'm just like u trying to gain knowledge and help others.... happy coding
