I am currently concentrating on Java programming skills. Right now developing a Energy usecase in Java with Spring framework. Have business requirement to generate data along with outliers. For example, have two parameters called as min and max (centigrates). Generate a file between min and max and store in a file. Atleast need to generate 10 outliers in each 100 records. Outliers should be < min and > max. How to write a java class with this business condition. The file should be like,
Java Code:
Public class DataGeneration(int min, int max)
where min = 30
max = 50
I have a string of variable tags (tag) filled with variables, and using a Scanner (scan) to manipulate and generate data dictionary add cards for each. The variables are delimited with new line character, and the variables are structured such that the actual name of the variable contains info as to its data type, size, etc. What I need to do is move the scanner to a particular point into the string then use .nextInt() or similar. I don't want to do this to the whole variable, just where I start it from. How can I do this?
Scanner scan = new Scanner( tag ); int ptr = tag.indexOf( "_" ); ptr++; if ( Character.toLowerCase( tag.charAt( ptr ) ) == 's' ) // then start at the "_" character and grab the nextInt()
Basic console java program. I need to generate an employee id. I have an employee class that I will paste here so you can see my fields and constructors.
public class Employee { private String firstName; private String lastName; private int id; public int nextUniqueId = 0; public Scanner sc = new Scanner(System.in);
Instruction: You work for a telemarketing company and you are required to write a JAVA program that will generate a random phone number. (talk about a real-world application)
-The phone number should consist of 10 digits -The first 3 are the area code and should not begin with 0, 8 or 9 -The second 3 digits should not be greater than 742 and not less than 100. -The last 4 digits can be any digits -Print the number using the following format: "(xxx)-xxx-xxxx", this way it will look like a real phone number (use decimal formatting)

I need to generate a bar chart given the data that is in main. The relative performance of each sorting algorithm with respect to time, number of comparisons, and number of swaps for each data set (e.g., 50,000 –400,000 random integers). Each algorithm will have 5 bars corresponding to the 5 data sets. The height of these bars will depend on the performance of the algorithm for that data set.
I know how to write a bar with normal values like integers but for this I'm not sure because the values for instance comparisons and swaps are not given they are calculated. I just need to know what steps to go about doing that, you can even express them in pseudocode or even just explaining it I don't need the code, I think. Here is the main
public class Main { public static void main(String[] args){ int t= 50000; int t2=100000; int t3=200000; int t4=300000; int t5=400000;
I have two threads, one generates data based on some decision process (A) and another use the data to plot it (B). The problem occurs when there is no data to plot. What is the best way to synchronize these two threads? Using sleep, or wait/notify?
I have to make a program on J2Me which I don't have a clue, the question is :
------------- "Initial display is a text box, with a command button "Generate". When the user enters the list type and clicks on the Generate button, the application asks count of elements and gets the elements and finally displays the list." --------------
I need to write a simple program that displays up to 5 pairings of data types (int, string) (string, long) ect. I need to have at least two classes, a Pair class (generic) and an PairTest class.
I am writing a java program which searchs data from a database on a website , my problem is that the url does not works on IE but works fine in other browsers..
So I was just wondering if it's possible to create a program with JAVA that uses an algorithm to summarize data inputed. I've never done something like this before, If this is not possible with Java is it possible with C++ or any other language??
I am now stuck. I am writing a program that reads information from a data file and runs it through but program. However, I am almost finished with the program, but cannot figure out the last few parts.

I have not attached the data file because it contains a total of 360 lines of hurricane information.
i am fairly new to java but have made a few projects so i do know most aspects that would allow me to complete the task its just i have been stuck at the same place now for 2 days.The project is to create a java program that can read specific data within a csv file to work out the averages etc. The csv file is a database of different weather stats . an example of the first 12 months of the csv file is below..
I know that once the data is indexed i can than use a double to find the average of the 12 specific pieces of data and so on. once this is complete i should than be able to transfer the data to a simple graph.
i want to generate n number of pdf here n will be some limit according to requirement so ultimately I have to generate more than 1 pdf same time with once running the code I Have some values associated with id i want to print those values with respective id's in pdf format, values can be in database or in some variable , which way i should go... i have some ideas either i can save those values in database and can make a single xml file from database of all records and then divide each node with different different pdf or directly get the values from database and generate the pdf.
I need to generate a file in Java with Unix TimeStamp. Want to generate an ordered list of Data entry objects for a defined period of time e.g., getData (long startTimeStamp, endTimeStamp, long resolution).
1) I would like to generate resolution with random numbers by using Random class.
2) How to take Start and end timestamps to generate a file (i.e., writing into a file).
I am trying to generate this request with my Java program, but I just can't seem to figure it out: curl -v -H "Authorization:Basic MY_AUTH_CODE" -H "Accept:application/xml" -H "app_id:MY_APP_ID" -H "app_key:MY_APP_KEY" -X GET "THIRD_PARTY_URL"
I tried to generate a query string, but I keep getting 403 errors. I also tried to input my parameters using URLConnection.getRequestProperty("name", "value"), but that didn't work either.
I am looking for java codes to generate a word document based on a word template, basically, I have a word template created and in my local path, the template has a proper format with some fields which will be filled in after java codes ran. The java codes will fetch one record from a table, and open the word template and then fill the fields in the word template, and created a new word document and save it in another folder.
I found this example: [URL] which is similar except it uses xml template instead of word template, how to make it work to change the template from xml to word (docx) template?
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road. If you choose to cross, the outcomes for 0-2 are "You crossed safely." For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street." For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working. I have up to here:
import java.util.Random; public class test4 { public static void main(String[] args) { Random random = new Random(); for(int i =0; i < 1; i++){ int num = random.nextInt(10) + 1; System.out.println("The number of cars on the street are: " + num + "Do you wish to cross the road?"); } } }
Write a program that allows the user to enter students names followed by their test scores and outputs the following information(assume that the maximum nmber of students in the class is 50; if the number of students is less than 50, to indicate the end of input data, after entering the last students data, on a line by itself, hold the ctrl key/press z and then press the Enter key):
a) Class average
b) Names of all the students whose test scores are below the class average, with an appropriate message( youre below class average)
c) Highest test score and the names of all the students having the highest score.
Use methods.
Now I wrote the program but i cant figure out how to end the input by pressing ctrl key/press z and then press the Enter key...
Here is my code
import java.util.Scanner; public class ClassAverage { public static void main(String args[]) { String names[] = new String[50];
I have a program that has a fair amount of data and the user can add to or edit the data. I would like to somehow combine the data with the program so they are all just one file. Like everything is in xxx.jar. When the program ends the data should be appended or in some other way become part of the program.Then wherever xxx.jar goes, the latest version of the data goes with it.I am doing it with a separate data file now but it is a problem keeping the data file with the program file.
While practicing java i have came across boolean data type. i have executed below program but i am not sure how i got output of the program like below:
10 > 9 is true
Here is my program:
class BoolTest3 { public static void main(String args[]) { System.out.println("10 > 9 is "+(10>9)); } }
My question is: how this program will come to know that 10>9 true or false.. how bolean data type used in this program.
1. Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
- The user wins the first prize if the user input matches all five digits in the lottery number in exact order. -The user wins the second prize if the user input matches any four digits in the lottery number in exact positions. -The user wins the third prize if the user input matches any three digits in the lottery number in its exact position. -The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
- The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.here is my code. I have tried replacing the && statements with || and it always returns either case 1 or case default.
import java.util.Scanner; import java.util.Random; class Hw5 { static int getPrize(int g1, int g2, int g3, int g4, int g5, int u1, int u2, int u3, int u4, int u5) {
I'm getting ready to code a program that takes record of items loaned and return in a table. I want more than one user to access the program to be able to update the data in the table. For instance, if one user added 5 new items to the table, all other users would be able open the program to see a modified table with 5 new items. Was looking for some advice and was wondering if implementing a database would work best.
