    Java Trouble with Buffered Reader and Exceptions in Java?

    Hello mathhelpboards community! I can't figure out how to get my code to execute while using buffered reader and try with resources. :-( I created a data.txt file correctly and it contains the numbers "0.5 3 10 70 90 80 20" without quotes. I added a catch IO Exception utilizing the...

    MHB Solving a Program to Take & Average Unknown Number of User Inputs

    Never mind, I figured it out. It doesn't stop between 5 and 10 inputs but as long as the user follows the prompt it should be okay. public static double [] getArrayNumbers(){ Scanner input = new Scanner(System.in); String numbers = input.nextLine(); String[] strHolder =...

    MHB Solving a Program to Take & Average Unknown Number of User Inputs

    I want to alter my program so it can take an unknown amount of elements (user inputs). I want the program to automatically count the numbers the user is inputting up until they hit enter to the next line. I think I got the program to keep track of this but now my output is a bunch of zeros in...

    Java Java Help with Methods: Solve Your Method Struggles

    I am having a difficult time with methods in java. I've been able to get my program to run correctly without methods. My for loop does as intended by printing an alternating rectangular pattern with no separator at the ends. However, after trying to decompose my code into 3 methods I've hit a...

    MHB Understanding nested for loops when decrementing

    I don't know why I thought the inner loop absolutely had to keep decreasing past 0. Also, I wasn't quite sure on placements for the braces but now I think I've got it. My teacher tends to not use them in her codes. Thank you for taking the time to help me learn. :-)

    MHB Understanding nested for loops when decrementing

    I'm sorry about that I should've been much clearer! There is no specific problem just a lack of understanding about decrementing nested for loops. The first code I had posted above used this particular line that I am having trouble wrapping my head around. #include <iostream> using namespace...

    MHB Understanding nested for loops when decrementing

    Hello! :-) I am having a hard time with understanding the logic behind decrementing nested for loops. The review problem I'm dealing with is below. This one makes the numbers go backwards. #include <iostream> using namespace std; int main(){ for (int i = 0; i < 5; i++){ for (int j = i; j >=...

    MHB Finding duplicates in a user defined array using a function

    My code almost does what I want it to do. It displays the position of the duplicate but does the last duplicate position instead of the first. However, I didn't know there was a function called find_first_of! I was trying to use break to exit out of the loop after finding the first duplicate and...
