See the below:
public static void main() {
int i; // counter
createDeck(); // this is a function call
// Show the cards in the deck
System.out.println("The deck is as follows:");
for (i=0 ; i < CARDS_IN_DECK ; i++)
[code]....
It is now printing out the value of myDeck[5] but I need to print out first 5 values.
The value is: ${object1.property1} If the value of the property is null, I want "null" to be printed, like this:
The value is: null But I get an empty string, like: The value is:
I know I can use a ternary operator, but isn't there a simpler/shorter solution? A function (like NVL() in SQL)?
The value is: ${empty object1.property1 ? "null" : object1.property1 }
Not only is this long, but the value expression is typed twice, which is a magnet for bugs.

My problem is where do I start or add the following code to be added?
I only want to use 1 array and may be or should I try a catch block? The number or numbers that were picked least frequently.
The average number of times that all of the numbers were picked. For example, the average might have been 210 times.
The number or numbers that were picked the average number of times.
The number or numbers that were picked most frequently.
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.Find the sum of all the multiples of 3 or 5 below 1000.

Java Code:
public static void main(String[] args) {
HashMap<Integer, String> stuff = new HashMap<>();
stuff.put(1, "Book");
stuff.put(2, "Pancake");
stuff.put(3, "Waffle");
for(Map.Entry thing : stuff.entrySet())
System.out.println(thing.getKey() + ": " + thing.getValue());
} mh_sh_highlight_all('java');
So I make a HashMap which is pretty simple. My book showed me how I would print all the values in a format showing their key a ": " and the the actual value. What I don't understand is why the type element for the for each loop is the interface, Map.Entry.
When I run this code, it is supposed to get one value from turnTimer(); and return it, just as a test. This works when I enter a valid pit. For example. If I were to input "A" when it's player one's turn, it will return 1, like it should. However, if I were to type "H" when it's player one's turn, it returns "Not a valid pit!"(like it should) but then it also returns 12. It shouldn't know that H is 12 because it's in a separate method. I'm confused as to why it's printing both values.

So I'm learning java from a website and I was tasked with creating a simple program which allows the user to enter a series of integers, then finally when they decide to input a non-integer the program will print the maximum and minimum values of the integers they entered. So for example if they entered 5, 4, 3 and 2 then enter a non-integer the program would output 5 (maximum value), then 2 on a new line (minimum value).
Here is my code:
import java.util.Scanner;
public class MaxMinPrinter {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int max = Integer.MIN_VALUE;
int min = Integer.MAX_VALUE;
[Code] ....
And this is what the output looks like:
Actual output
-------------------------------------------
Enter an integer: 5
- 10
-
- Enter an integer: -4
- 8
- -6
-
- Enter an integer: 11
- -1
-
- Enter an integer: q
- -1
- -6
When it's supposed to look like this:
Expected output
-------------------------------------------
Enter an integer: 5
Enter an integer: 10
Enter an integer: -4
Enter an integer: 8
Enter an integer: -6
Enter an integer: 11
Enter an integer: -1
Enter an integer: q
11

I had to write a foor loop to count the values of a stack of quarters from 1.00 to 3.00 and I had to print the values, that I understood and got it working so I taught the next assignment was going to be easier but I am having a hard time with it. For this one I have to write a for loop to print all the positive integer factors of 144 and I am supposed to print of factor per line but I tried doing that but it doesn't work it just prints out 144.
This is my code. The quarter assignment is also in there because it is part of a lab so just ignore that part since it is working correctly.

// To print rounded, use printf, with a placeholder of %.2f
// (%f is the floating-point placeholder; the .2 indicates the number of decimal places)

Purpose: To write the methods and the rest program. The program should fill a 4 X 4 2 dimensional array with random numbers between 100 and 200. The program should then determine and print the largest and smallest values within the array using two Methods Largest and Smallest. The program should then determine and print the number of values within the array that are even using a function called Even. The program should also enter a loop that will only terminate when the user inputs a -1 as a choice. The loop should continue to ask the user to guess a number that was randomly generated. The program should call the Findit function to determine if the number was in the array. The program should print out the values in the array when the user selects a -1 and then terminate.

I just had this code working, then all of a sudden i was hit with a 'keyboard leak' error code.
Basically the class is supposed to have a static variable that keeps track of the number of companies (numberOfCompanies) that have been created and a static method that returns the value of this variable. I need to have a constructor and a method to addEmployee, a method to printCompany, and a toString method. The addEmployee method will check that there is only 1 salesperson, 2 designers, and 4 manufacturing persons at a time and will check that there are no more than 7 employees of the company.
The addEmployee method will return a String indicating what the error is (i.e. "There is already a sales person in this company") or a null if the employee was added. If attempting to name a third company, an error message will be shown. what i have so far but my print company mmethod returns null company class :in which i am obliged to use inputdialog because it says that it cannot return void when i use the showmeassage diaolog.

I need a way to store the pixels values currently on the screen and compare them to the values on the first frame. Right now I'm using glreadpixels as follows:
currentBuffer= BufferTools.reserveByteData(mapSize);
glReadPixels(mapStartX, mapStartY, mapWidth, mapHeight, GL_BLUE, GL_UNSIGNED_BYTE, currentBuffer);
for (int i = 0; i < mapSize; i++) {
if (currentBuffer.get(i) != baseBuffer.get(i)) {
//Do nothing
continue;
}
//Do something
}
This works perfectly fine but turns out to be a real bottleneck, dropping the fps to a third of what it was. Is there any quicker way? All I'm after is speed, I don't even need to show it on the screen if the comparison is made "behind the scene".
I have a question in mind that this is my registration form. I am sending these values from HTML form to server and database. I have question that in my case if I click next to Add Another Mobile no in HTML.then a block is genereated and each time a new name is generated.
My Question is if I click 6 times then 6 name attribute are generated. How can I send and differentiate them on my server side.
Because at their I will use something request.getAttribute("Attr_Name");
But they are same. How to do this?.
I have a JScrollPane with two coulmns. In the first column I have an image pane JTable, and in the second a list with names of sections. This second column I try to divide in two columns, one (the second column) to display the names of the sections (each row contains one name), and in the other column (the third) I want to show some values for every section in the row respectively. But, instead of displaying the desired values in the third column, I get the same names of the sections as in the second column.
View Replies View RelatedI'm doing an aggregation exercise that's suppose to find the volume and surface area of a cylinder. What I'm trying to do is pass values from one class, to a second class, and that second class passes values to a third class.
This may be a clearer explanation: The first class is the main program which sends values to the second and third class. The second class is used do calculations for a circle (a pre-existing class from another assignment). The third class grabs the values that the second class calculated and calculates those values with the one that was passed from the first class to the third class. The first class then prints the outcome.
Problem is when the program gets to the third class, it just calculates the value from the first class with the default constructor from the second class. It's like the second class never received the values from the first class. I think I'm missing a step, but I don't what it is.
First Class:

I am currently trying to print a Diamond using for-loops but I seem to be confusing my self / over-complicating it.
This is what I have so far [URL]). When I run the code I get [URL].

Also, is there a faster/efficient method of doing something like this?
Implement a Las Vegas slot machine! The machine works as follows. First, it generates three random integers (use import java.lang.Math.*; then call Math.random()*7 to generate a random number between [a,b)) that are in the range of 0-7. Once the numbers are generated, the following rules are used to determine the prize:
- If all three numbers are equal to 7, you are winning $1,000,
- If all three numbers are equal, but not equal to 7, you are winning $500,
- If two of the numbers are equal to 7 and the third one is six, you are winning $400,
- If two numbers are equal, you are winning $100,
- Otherwise you are not winning anything.
And for that I wrote:
import java.lang.Math;
public class Assn1_2150130 {
public static void main(String[] args) {
// Generate three random signle-digit integar from 0-7.
int n1 = (int)(Math.random()*7);
int n2 = (int)(Math.random()*7);
int n3 = (int)(Math.random()*7);
[code]...
But I just can't figure out a way to print out the "YOU WON NOTHING." independently.If I say that n1!=n2 && n2!=n3 && n3!=n1, and then write another line of println. It gives out the number as well as the "NOTHING".
I want to write a while loop to print all odd numbers between 1 and 100.
But it gives error. Where is the mistake?
