Write A Java Program That Reads 5 Integers
Oct 9, 2014
Project is due before midnight eastern time (3 more hours). I have been working on this all day, we have not learned arrays or anything and just started 'for' loops. I don't really know how to implement that system yet. However, he wants us to check all the possible handwritten math ways of doing this. I have tried but I cannot return my numbers beside the card.my program only prints the type and I still have more cases to add as well..
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)
[code]....

Write an application that reads five integers, determines and prints the largest and smallest integers in the group. Use only the programming techniques you learned in this chapter. (which means: use only if statements and the equality and relational operators).If I want to solve this I will write nested if statements for every probability like the following.The probability: the first integer is the largest and the fifth integer is the smallest:
1>2>3>4>5
1>2>4>3>5
1>4>3>2>5
1>4>2>3>5
1>3>4>2>5
1>3>2>4>5
And so on for every probability.

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.

a. Assume that we have a list of employees' names of a company and their ages. Write a program that reads from the user several lines of input. Each line includes an employee's name and his/her age (as an integer). The program should calculate and print the following:
- The average age of all employees (rounded to 2 decimal places).
- The oldest employee and his/her age.
Hints:
You could assume that the user will insert valid data and at least one employee.
You could assume that the oldest employee is only one person.
User could stop the program via entering the word "end" as an employee's name.
Sample Input and Output: In each line, insert an employee's name and his/her age To halt the program, insert "end" as an employee's name
Adam 30
Tom 41
Ted 45
Karl 30
end
The average age of all employees is 36.50.The oldest employee is Hisham whose age is 45

I was wondering if it's possible to do this: I want to build a java program that reads a java array from a text file.
Then I want to read it, and output it in a different format.
The reading and out is easy - as text.
But how can I incorporate the read text in to a java valid array in my program, which I can use?
Is this even possible?

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.
import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

Scanner scnr = new Scanner(System.in);
int userNum = 0;

I 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.
/*
* File: UniqueNames.java
*/
import acm.program.*;
import java.util.*;

Ex. If I type 5943, the program will say
mill = 5
hun = 9
ten = 4
uni = 3
get the picture I had to translate the decimal value names from a different language.
This is what I have tried...,
Java Code:
import java.util.Scanner;//Permite el uso de leer el teclado del usuario
public class DeterminarValorDecimal//Nombra el documento
{
public static void main(String [] args)//Podemos ver la clase
{
[Code].....
But what this does is I have to enter the single digits one by one. I want to be able to type the whole number. Is there a method that reads the length of the whole number and lets me classify each digit so I can do what I want to do?

Write a Java program that calculates the area and volume of a cube, sphere, cylinder, and regular tetrahedron. Your program should obtain the necessary input for each of the objects from the console and output the input, area, and volume of the object. Use appropriate messages to guide the user of your program.
Here what i did, i am not sure if this is what the assignment want, but this is the best method i could come up with

I want to write a java program which displays to get the GPA of a student as a keyboard input. Then display the class of the degree according to the following criteria using a switch-case statement (if-else statements cannot be used). If the user insert an invalid gpa you should display a message Invalid GPA.
gpa ≥ 3.50 First Class Hons
3.49 ≥ gpa ≥ 3.00 Upper Second Class Hons
2.99 ≥ gpa ≥ 2.50 Lower Second Class Hons
2.49 ≥ gpa ≥ 2.00 Pass
2.00 ≥ gpa Fail
Here is my code:
import java.io.*;
public class q7
{
public static void main(String[] args)
{
InputStreamReader ISR=new InputStreamReader(System.in);
BufferedReader BR=new BufferedReader(ISR);
[code]...
.But when I use Command console to run this it says: 1111.jpg. I also wanna know is there another way to do this with switch- case statements.

For the latest assignment, my instructor has asked us to create a program where we create lines of at least for integers and if the program registers there being four of the same integer horizontally, vertically, or diagonally it returns true. For example:
1 1 1 1 1 2 3 4 1 2 3 4
4 3 6 2 2 1 4 5 1 5 6 7
8 2 0 3 3 2 1 6 1 3 5 7
4 7 9 3 5 7 4 1 1 8 9 0
If the program doesn't see four integers of the same value anywhere, it is supposed to return false. I've got it so it returns true for the lines above, 6x6 lines of integers and lines where only four out of six+ integers are equal. However, I cannot get my code to return false if there are only three matching integers in a row/column/diagonal nor can I get the program to print out either true or false for lines that do not start at the top left corner. (i.e 2 3 1 1 1 1) For the former I get this error message:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
at ConnectFour.is4Consecutive(ConnectFour.java:41)
at ConnectFour.main(ConnectFour.java:32)
For the latter:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 6
at ConnectFour.is4Consecutive(ConnectFour.java:43)
at ConnectFour.main(ConnectFour.java:34)
The answer to fixing my code is probably something small or something that will make me wonder why I hadn't thought of it myself... Here is my code:
import java.util.Scanner;
public class ConnectFour {
private static Scanner sc;
public static void main(String[] args)
{
sc = new Scanner(System.in);
System.out.print("Enter the height: ");
int h = sc.nextInt();
System.out.print("Enter the width: ");
[Code] .....
1 1 1 1
4 3 6 2
8 2 0 3
4 7 9 3
1 2 3 4
2 1 4 5
3 2 1 6
5 7 4 1
1 2 3 4
1 5 6 7
1 3 5 7
1 8 9 0

I'm required to create a program that finds the minimum value in an Array of integers.
Here is my approach :
public class Person {
public static void main(String [ ] args){
int theArray[]=new int [10];
int result = 0;
for (int i:theArray){
if (i < Integer.MAX_VALUE)
[Code]...
I can't really progress from this position. I keep getting told to change the return type to int on main method, then when i do it says change it to void..

I'm playing with vectors for the first time... What I'm trying to do is to allow a user to input one or more integers and store them in a vector for manipulation later on in the program... Here's the portion of the program I'm working with:
Java Code:
package com.itse2317;
import java.util.*;
public class VectorTest
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
[code]...
My question is this: Is there any way to move from inputting integers to printing them, without entering a non-integer (for example, hitting enter)? I looked at the API for the Vector class, and either I'm not thinking about the problem the right way to be able to find an answer, or it's just not there.
