Program Deals With Variation Of Geographic Coordinate System
Aug 22, 2014
This program deals with a variation of the geographic coordinate system with Greenwich at 51° 28' 38" N. The program will be adding the three values of one coordinate to the three values of the second coordinate. Though the maximum value for seconds and minutes is 59, the user can enter values greater than that number when prompted. The maximum degree is 360 for this assignment though the user can enter values greater than that number.
I've been pondering about this algorithm for about a week but I'm still not able to write a "fast" working method/algorithm to solve the Number-of-paths-exercise we were given in my class />
So here's the task: Write an efficient java program "Paths" which solves the following task:
- Read input n ∈ N and give output a(n) which is the number of paths from (0,0) to (n,0) it is not allowed to go over the diagonal (m,m) and also not below the x-axis (m,0)
Here are the allowed steps: u = (1,1), U = (1,4), d = (1,−1), D = (1,−4) and H = (1,0) steps are performed in a two-dimensional-coordinate-system!
Ok so this is a grading program. I have it so the user can input 2 students and then at the end using an if statement it is suppose to compare them and print out who had the higher grade. Seems simple but it never runs the line of code to print out whos grade is higher:
if (stuAverage > stuAverage2 ){ System.out.println(student + " has the highest grade of all students entered!"); } else if (stuAverage2> stuAverage){ System.out.println(student2 + " has the highest grade of all students entered!!"); }
Here is the Main class:
import java.util.Scanner; public class Main2 { int stuAverage; static String student;
So i was assigned to write a program that would print the answer to the system of two linear equation. the form of ax+by=c and dx+ey=f..I wrote this program, but it is incorrect since I tried it out on my terminal and I keep getting incorrect values.
import java.util.Scanner; public class Quest4 { public static void main(String[] args) { Scanner input = new Scanner(System.in);
Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code
package gradingapplication; import java.util.Scanner; public class GradingApplication { public static double score(double score){ if(score >= 90){ System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.
I just started programming yesterday, and I have been making little programs to learn some algorithms and the syntax of java. I tried making a program that could convert metric units into the American system. Whenever I try to compile the code, it shows up as an "incompatible type" error. I know this is probably a very obvious answer to most of you, but I can't figure it out.
import java.util.Scanner; public class MetricToAmerican { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("fWhat measurement would you like to convert into US system? celsius, meter, or kilogram ");
I have a set of 2D arrays, structured as so: int[][] cage = new int[someLength][4]. Each array has a set column length of 4; the first two columns are all that concern us with this problem. They are used to define the row and height respectively of a point (e.g. 2,4).
What I need is to generate all possible permutations of the points using both row and column coordinates from the 2D array. I found a working method to generate all permutations for 1D array of ints here: [URL] ..... , under update 2 of the first answer.
Here is an example of a possible input and corresponding output desired:
In: (1,0) (1,1)
Out:(1,0),(1,1) (1,1),(1,0)
Ideally the result will be stored in a 2D array of ints.

I do now have the problem where i have to insert the numbers 1 to 100 individually in order to allow the program to accept a grade as high as 100%.
Also as soon as i type in a negative number the system crashes and shows me a error as attached.

Many classes calculate a final grade by using a weighted scoring system. For example, "Assignments" might be worth (weighted at) 40% of your final grade. To calculate the portion of the final grade contributed by the Assignments category, the teacher takes the average of all assignments in the category and multiplies it by the weight (40%). So if a student averaged 90% on all assignments, the teacher would take 40% of 90%, or 36 as the weighted average score for the assignment portion of the the final score. The teacher then calculates the weighted average score for each of the other categories (Quizzes, Midterm Exam, Final Exam, etc.), adds them all together to come up with the final score, and assigns a letter grade based on that score.
Write a Java program that allows the teacher to calculate the grade for a student.
Specification :
Prompt the user to enter the Student ID number, first name, last name, and the average score for each of the following categories:
Ok Im trying to create a code right now that will take a table of rectangular coordinates and convert them to Polar coordinates in the constructor. I will eventually calculate the total distance between all points in the calculateDistancePolar method but for now I am using it to test.
It doesnt like line 29 and 31 of the class Polar and I cannot figure out why.
public class Test { public static void main(String[] args) { double[][] coords = {{86.92, 2.47},{70.93, 27.81},{97.74, 34.36},{30.90, 35.14},{51.66, 31.70},{0.830, 21.77},{55.91, 66.62},{32.92, 75.23},{65.26, 72.53},{83.90, 4.710}}; System.out.println("X,Y Coordinates are:"); outputArray(coords); Polar myTest = new Polar(coords);
I develop a finite element code at java. I am looking for efficiency solver and fast for large, sparse , symmetric and positive define matrices .
i used in jblas but i encounter in problem when the matrix has high condition number(ill condition number) and i get error for singular matrix while in mathematica i succeed to solve that system without problems...
Any good solver and fast solver package in java can i use for solving that system?
I'm having a random x and y coordinate generate and I need to check if the coordinates are inside of a right triangle on this imaginary coordinate plane.
I have the Java Development Kit downloaded in my C file and my book tells me to compile the program I need to open command windowand change the directory where the program is stored. I tried the command cd to change directory and received this message "The system cannot find the path specified."
I checked the Environment Variables on Windows 7 and the Path says: C:Program Files (x86)Javajre1.8.0_31in
This is after many tries and i still can't change directory and i keep getting the same message.
I'm making a stock system for the heck of it,so everything was going great until I hit the loop I am trying to use a for loop to add stock to the stock system,any way the question is maily about loops.How come I cannot declare a variable outside a loop and assign a value to it,for example I can declare as follows and I will not get an error,
but in my code(and yes its the only error I get I tested it) I get an error and can only declare and assign a value inside the loop,the reason for this is because I wanted to get the value from another class and use it in the loop ok so heres the code from both classes.
public class mainn{
public static void main(String [] args){ stock first = new stock(); int internal; internal = first.wanted;
it gives me an error at the end class part some syntax error insert "}"..

We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.
In my java program I'm changing my IP(using proxy) and sending the request to some sites. Later some point of time, I want to know my current IP address through java program itself. How to get hold of my current IP address? Also which IP address will it show? The proxy one or the original IP ?

I just want to calculate search time for my algorithm . How to get system time in java other than System.nanotime() and System.currenttimemillis() as these methods does not returns consistent time for same input is their another option to get system time???
