I dont think so... because my sortArray method doesnt work how I thought it would...

First of all, thanks so much for the reply! Option 2 sounds like what i want to do. Because I do not need the duplicates. However, how would I go about zeroing them out and only printing non-zero...

Like i said. I cannot use separate classes, they must all be in one. My question is how can I go about sorting them... I don't have a clue how to sort the scores.

This all has to be in one class. Thanks for the response though!

I am making a program that asks for how many students and based on that answer a number of boxes come up asking for their name and their score. After it is supposed to sort them from best score to...

So my code asks a user to enter 10 numbers, it then checks to see if the number is already in the array, then prints out the entered numbers in a dialog box, but does not print duplicates (i.e. if...

Scratch that. I fixed it.

Thanks! Works perfect now. I figured d stood for double, good to know. I appreciate the fast and informative response!

public static void main(String[] args) {
double meter;

I was making a program that told you whether or not the integer you entered was divisible by 5 and 6, 5 or 6, 5 or 6 but not both. The first 2 worked fine with the way I did it and displayed true or...

I am programming in NetBeans. The default console output is normal black. All i need is to bold it.

I am creating a program that prompts the user to enter a year and the first day of the month, Sun=0, Mon=1, etc . . . then shows that years calendar with the correct number date placement, but I am...

When I use that format it is actually turning my text gray and not bolding it...



String bold= "\033[1mJanuary\033[0m";
System.out.printf("%100s\n", bold);

Well the thing is this is for a class I am taking and the teacher wants it bold, yet he didn't teach us how to bold and I can't find it in the book anywhere. Thanks for the help.

The program I am creating displays the output into the console and prints out tables. I want the header of these said tables to be bold, how can I do that?

here is what I want bold:



...

nevermind, i actually ended up figuring it out.

Heres what I ended with:



import java.util.Scanner;

public class Pg127 {

heres what i have so far... dont have the divisibility equation yet.



import java.util.Scanner;

public class Pg127 {
public static void main(String[] args) {

//Input...

well actually it doesnt have to be boolean i realized. I have no idea how to see if a number is divisible by another, so help needed there. But as for the data type i just need one that states true...

i am making a program to see if a number is divisible by 5 and/or 6. how do i do this using a boolean? the user inputs and int and then i calculate it and tell them true and/or false. thanks

what do you mean "something correctly" and "something done wrong"? Could you provide an example please? Thanks for your response

So i am writing a code to display the windchill temperature, the user enters a temp and windspeed and they are given the windchill temp. The thing is they have to enter a temp within -58F and 41F, I...

Thanks for that. the first 5 months can be displayed in the code, but the 6th is all that is wanted in the dialog box after running the program. I just didnt know if i had to manually put in all the...
