Hey everyone again,
I'm trying to display 3 distinct integers from user input
the length of the array is also 3
so for example:
1, 1, 2, 3, 4
the distinct set would be 2,3,4
Here is what I have so far, however at the moment it is terminating after the I input data the 3rd time, and not letting me collect all 3 unique numbers before printing

Displaying Distinct Numbers from Array
10 October 2012 - 08:44 AM
Array accept only positive values
10 October 2012 - 12:44 AM
import java.util.Scanner; public class test { public static void main (String[] args) { Scanner scan = new Scanner(System.in); System.out.println("Enter numbers: "); int num = scan.nextInt(); int numbers = 5; int array[] = new int [numbers]; int numCount = 0; while (numCount < numbers) { array[numCount++]=scan.nextInt(); } for(int i:array){ System.out.println(i); } } }
I'm trying to do two things, make it accept only positive numbers from user,
and also to terminate if the user enters 0
And also when I enter like the numbers 1,2,3,4,5,6
in a row it omits the first 1 I enter, and only stores the number 2,3,4,5,6
Any help would be appreciated
Displaying Percentages of Columns in SQL
18 September 2012 - 06:50 AM
Hi,
I have a table, and this is what I'm trying to do
i have to count 2 columns and then use the counts to divide them and multiply by 100 to get the percentage, then what the answer wants is 100-85, and it also has to be rounded to 2 decimals
column1, column2, Percentage
204 240 100 - 85 = 0.15
SELECT COUNT(column1) FROM table
SELECT COUNT(column2) From table
SELECT ROUND(column_name,2) FROM table_name
yeah, just not sure how to use those 2 counts, and add another query to calculate the percentages from the counts.
Any help is greatly appreciated!!!!!!

Checking if a string contains upper or lower case letters
03 September 2012 - 09:33 PM
Hi,
I have to receive user input via the scanner, and then
check if the word they entered contains upper or lowercase letters,
would the method isUpperCase & isLowerCase work??
If so how would you apply it to strings.
Or would i have to use string.length and char.At??
Thanks any help is appreciated
