I am working on the following simple question of Java: "Write a program called Product1ToN to compute the product of integers 1 to 10 (i.e., 1,2,3...10). Try computing the product from 1 to 11, 1 to 12, 1 to 13 and 1 to 14. Write down the product obtained and explain the results."
public class HelloWorldApp {
public static void main(String[] args) {
int lowerBound = 1;
int upperBound = 10;
int product = 1;
I have the following code Java (is it just a meaningless example ), my question is: if I wanted to insert a code to multiply two fraction into moltiplicaPer() metod What should I write?
public class Frazione { private int num; private int den; Frazione() { num = 0; den = 1;
I am not sure what is happening with my code, but it is giving me a negative number. I am trying to write a program that calculates the product of the odd integers between 1 and 25. I messed with the program and as soon as you enter a number over 22, the end result is a negative number.
int total = 1; for (int i = 1; i <= 25; i += 2){ total *= i; } System.out.println("Product:" + total);
The question is when you send two messages from the client to the server does the server read the messages as one input or do you have to read both inputs on the server side?
Im using DataInputStream and DataOutputStream
On the client side I send two messages one for the database action to be performed and the send is the information needed to get the job done.
Example I want to search for a product in the database.
I send to the server an output message saying search product. I then send to the server which product I want to be searched.
The server then retrieves the message by in.readUTF(); switch statement determines what database action should be performed. Within that case I call another in.readUTF() to pass the information to the database on what product to search for.
Would this work or would the server read both messages from the client as one input stream?
We have an application running successfully where we fetch the weight of product currently on Production Line using Java.
All the products on line belong to same order and are of same type. User at beginning enter the type of product and starts the production line.
Proposed new process: Now client want that multiple type of product can belong to same production order. i.e. on a production line different type of products can come one after other. So we should now fetch the type of product also.
The Question : what are different possibilities in which we can find the type of product. Can java fetch color of a box ? If we use scanner on line that scans the product and sends the color information to Java.
Above is just a possibility. Can there be any other parameters that Java can use to differentiate in type of product ?
Currently we are clueless. What ever are the possibilities in Java we can propose the same to client. Even if that requires additional hardware.
I wanted to know if I was off to the right start. I am trying to write a program using the for loop the calculate the product of the consecutive numbers 4 through 8 but so for I am getting 3 values output and I only want 1 value at the print out.
The code I am using outputs the numbers too large. I am trying to see where I went wrong.
for ( int i = 4 ; i <= 8; i++) { int j = i++; int k = j++; int l = k++; int m = l++; System.out.println( + (i*j*k*l*m) ); }
What I am trying to do here is allow input to loop until 0 is entered for the product number. When 0 is entered, it should then dump the total for each individual product. I've tried it about a dozen different ways and have yet to be able to get the loop to function as intended. The way I have the code below, the loop will not function at all (where as before it looped, but never finished).
import java.util.Scanner; public class Sales { public static void main(String[] args) { double total1=0.0; double total2=0.0; double total3=0.0; double total4=0.0; double total5=0.0; int product;
My problem is that in my program, I have the user input data for one of three product objects, however when I read the data for all three objects, the same data is stored in all of them.
Anyway this is the method from the Interface class:
private void readInput() // the only method in the program that accepts product data from the user { Store matesStore = new Store(); String name; int demandRate, productChoice; double setupCost, unitCost, inventoryCost, sellingPrice; Scanner console = new Scanner(System.in);
[Code] ....
And here is the method from the Store class:
public static void addData(int option, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice) //sets the product data for a particular product { if (option==1) setData(product1, newName, newDemand, newSetup, newUnit, newInventory, newPrice); else if (option==2) setData(product2, newName, newDemand, newSetup, newUnit, newInventory, newPrice); else /*(option==3)*/ setData(product3, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
[Code] ....
The problem I had was with static variables and methods.
public class InputFileData { /** * @param inputFile a file giving the data for an electronic * equipment supplier’s product range * @return an array of product details * @throws IOException */ public static Product [] readProductDataFile(File inputFile) throws IOException{ // YOUR CODE HERE }
This code is meant to be used to read a text file and store the data in an array of type Product[]. I know how to read in a text file and have it sort it into an array, but I've never seen code laid out in this fashion before (specifically "public static Product[]", and I'm unsure how to work with "(File inputfile)". I've looked all over the place but can't find any examples of anything like this.
Also, the code given cannot be changed, as it's that code I have to work with.
I still don't understand how to use it as a whole. For example, do I read the file in the main and have this method read that in and output to the Product class? Do I read the file in this method? I can't work out how to make this work when I have to use this method.
The Program prompts the user to enter the number of products in the product catalog. The program should then prompt the user for the name and the price of each product in the product catalog. Once all of the products have been entered, the program should output the product information (name and price) of the most expensive product in the catalog. Your solution to keep track of the product with the highest price.
import java.util.Scanner; public class ProductTester { private static final String price = null; public static void main(String[] args) { Scanner console = new Scanner(System.in); System.out.print("Enter the number of Products: "); int count = console.nextInt();
I want to display product details such as product image, name, price in a one cell of a table tag on jsp page. There should be multiple rows and 3 cells per row in the required output.i have written the following code:
This code displays all cells in only one row. I used colspan but its not working...I have attached the snapshot of above code output and required output
Have written a program to open Excel sheet from java program.Below line works fine.
Process p = Runtime.getRuntime().exec(new String[]{""C:Program Files (x86)Microsoft OfficeOffice12Excel.EXE"","C:UsersRASHPA~ 1.ORAAppDataLocalTempExport_xl420314062726 9379706.xls"});
But below code gives error i.e. Executable name has embedded quote, split the arguments
I'm creating a program that will compile and run another java program:Lets say I have a program in directory
D:HelloWorldsrc and compiled program will be in D:HelloWorldin inside src and bin is a folder hello (that's a package)
package hello; public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World"); System.out.println("Hello World"); } }
This program will be run by another program (that's the program that I am creating).Here is the code of my program:
package runnercompiler; import java.io.IOException; import java.io.InputStream; import java.util.logging.Level; import java.util.logging.Logger; public final class RunnerCompiler {
I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,
I have to read two pair of words as array from keyboard and then check corresponding words are anagram are not. If they are print 1 otherwise 0. Total number of words in the pair cannot exceed 100, the word length cannot exceed 100 and only lower case letters are allowed.My code is the following:
import java.util.Scanner; import java.util.Arrays; class MyClass { public static void main(String[] args) {
I have spent quite a few hours trying to follow an API on how to use Actions in a java program.
I have 3 JButtons and have just added a JMenu. What I want to do is to add an ACTION so that the JMenu performs the same function as the JButtons. (i.e. they both do the same thing).
I have tried to copy and follow the example from the API forum.
How to Use Actions (The Java > Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
The first error I get in compiling is on the following line:
Action loadFile = new LOADFILE();
However, I get the following error message:
softeng2final2.java:49: cannot find symbol symbol : class LOADFILE location: class softeng2final2 Action loadFile = new LOADFILE();
I'm new to this so take it easy on my code!! It compiles but its not giving me the correct outputs and I can't figure out why. Two words or phrases in English are anagrams if their letters (and only their letters), rearranged, are the same. We assume that upper and lower case are indistinguishable, and punctuation and spaces don't count. Some examples and non-examples:
* The eyes / they see (yes) * moo / mo (no) * Clint Eastwood / Old west Action! (yes) * Dormitory / Dirty Room (yes)
For more examples, see here.
Your job for this assignment is to solve a slight variant of the traditional anagram problem called superanagram. Here you are to write a two class application that reads in two words or phrases from the keyboard, and then judges if the first phrase is an anagram of some of the letters in the second phrase. Here are some examples:
* mo / moo (yes) * mo / mOO (yes - capitalization doesn't matter) * moo / mo (no - first phrase is NOT an anagram of some (or all) of letters of second) * rip / ziPPer (yes) * abc / aabc (yes) * aabc / abcde (no - too few a's in the second string) * flipper / rip (no) * Clint Eastwood / Old west Action! (yes - the two can have exactly the same letters)
You must use the Scanner class to read in the input strings. Use the nextLine() Scanner method, rather than next(), since spaces may be present in the two phrases that are submitted.Your program should either print YES, if the superanagram relationship is satisfied, or NO, if it isn't.
The classes MUST be called SuperAnTester, and SuperAnagram
* use the String methods toLowerCase() and (possibly) toCharArray(). The former takes all letters in a String and changes them to lower case; the latter converts a String into an array of characters. Also, this assignment is - of course - about characters and character matching. For some useful background on characters and how to work with them, watch the movies in the textbook at the ends of section 4.1 and 7.1.
* Very important: suppose you have two arrays of characters such that the first is purported to be an embedded anagram of the second, in the sense we've described above. How can you tell? The single most important thing to do, before you write a single line of code, is to work out a paper and pencil algorithm that distinguishes between superanagrams and non-superanagrams.
* Your classes must be commented! In particular, each method must have a one line comment just below the header line, which tells what the method is supposed to do.
* Algorithm Idea #1: make a scoreboard for the letters a to z. Every time you encounter a letter in the second String, up its count by 1; Then, every time you encounter a letter in the first String, lower its count by 1. Accept if the scoreboard ends up with all entries >= 0. (of course make sure you understand why this is - use pencil and paper to convince yourself!!).
* Algorithm Idea #2: convert strings to arrays. March down first array (representing the first string). When you encounter a letter, look for it in the second array. If you find it, blank out the occurrence in the second array; if you don't find it - it's not a super anagram. When you're all done, you've got a superanagram if your search in the second array never goes bad.
public class SuperAnagram{ private String wordOne; private String wordTwo; private char firstArray[]; private char secondArray[];
It would be made through a 2d array and the values for how big the lines are would be stored in another file called line_details.txt which contains these values 0 200 1 175. So how would I implement this stuff into a Java code?
This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.
