QUESTION: Write a Java program that reads 5 integers, each of which is in the range of 1 and 13 representing a simplified poker card with no suit. Your program should then print the ranking of the hand with card number(s) beside the ranking. The rankings to determine are Four of a Kind(4 of the 5 cards of the same rank), Full House(3 of the 5 cards of the same rank, and 2 cards of another rank), Straight(5 cards of sequential rank), Three of a Kind(only 3 cards of the same rank), Two Pair(2 cards of the same rank, 2 cards of another rank, and no card of either rank), One Pair(only 2 of 5 cards are of the same rank), and High Card(no two cards of the same rank). Some sample runs are:
input: 2, 3, 2, 2, 2; output: Four of a Kind(2)
input: 2, 3, 2, 3, 2; output: Full House(2, 3)
input: 2, 3, 4, 5, 1; output: Straight(5)
input: 1, 13, 11, 10, 12; output: Straight(1)

Write a java program to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class.
View Replies View RelatedI have an excel spreadsheet, with a specific filename and location which doesn't change (e.g. C:/workbook.xls)What I would like to do is have a window open when I open an .exe file, and in this window is a bunch of check boxes, text areas and drop down boxes (I can implement these, that's about my level of JAVA)
Then, when I click on a button in this window (for example, a button which says "Save"), the data from all these boxes and menus etc. goes into specific cells in the excel spreadsheet. Or if certain values are selected from a drop down menu, then a bunch of cells are empty.
I am trying to write a java program that asks the user for a list of names (one per line) until the user enters a blank line. At that point the program should print out the list of names entered, where each name is listed only once (i.e., uniquely) no matter how many times the user entered the name in the program. I am supposed to use an ArrayList for this problem.
My idea for a solution is to create an ArrayList<String>, read each name, i.e., line, entered and then to see if that name is already in the ArrayList. I created a for loop to check each element in the ArrayList but when I try to assign an element to a string variable I get the error "Type mismatch: cannot convert from Object to String". Not sure why that is happening because the ArrayList is defined as a String list.
Here is the code so far.

Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.
A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 > 1 + 2 + 4, while the number 12 is abundant, since 12 < 1 + 2 + 3 + 4 + 6.
SAMPLE OUTPUT:
1.)Input N: 5
5 is deficient.
2.)Input N: 6
6 is perfect.
3.)Input N: 18
18 is abundant.

i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.
1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.
2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.
So i created 2 classes, one called Coin.java & the other CountFlips.java,
PHP Code: package test;
public class Coin {
private final int heads = 0;
private final int tails = 1;
private int facetype;
private int flips;

How do you declare methods for a class within the class whilst objects of the class are declared else where?
Say for instance, I have a main class Wall, and another class called Clock, and because they are both GUI based, I want to put a Clock on the Wall, so I have declared an instance object of Clock in the Wall class (Wall extends JFrame, and Clock extends JPanel).
I now want to have methods such as setClock, resetClock in the Clock class, but im having trouble in being able to refer to the Clock object thats been declared in the Wall class.
Is this possible? Or am I trying to do something thats not possible? Or maybe I've missed something really obvious?
