How can I get this to work? I have the popup window where it pops up but I'm using Netbeans and the data I want in the popup box isn't in there.. it is in the netbeans runner thing. By the way don't judge the look of this code I except all criticism, but I'm only 13.
Code:
package FunctionSolver;
import java.awt.Canvas;
import java.util.Scanner;
import javax.swing.JFrame;
public class Main extends Canvas {
public static final int WIDTH = 800;
public static final int HEIGHT = 600;
public static final String TITLE = "Linear Equation Solver";
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.pack();
frame.setTitle (TITLE);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(WIDTH, HEIGHT);
frame.setLocationRelativeTo(null);
frame.setResizable(false);
frame.setVisible(true);
System.out.println("This solves both positive and negative functions.");
System.out.println("This is a function solver(only linear equations)");
System.out.println("Max of three variables.");
System.out.println("When righting fractions only use decimals like let's say you want 1/4 it needs to be .25 Thank you.");
Scanner input;
input = new Scanner(System.in);
System.out.println("What Is Your Coefficient?");
double coef = input.nextDouble();
System.out.println("What is your constant?");
double constant = input.nextDouble();
System.out.println("What is your x variables?");
double a = input.nextDouble();
double b = input.nextDouble();
double c = input.nextDouble();
if(constant<=0)
{
System.out.println("FUNCTION: = f(x) = " + coef + "x" + constant );
System.out.println();
}
else
{
System.out.println("FUNCTION: = f(x) = " + coef + "x + " + constant );
System.out.println();
}
System.out.println("x Variables:");
System.out.println();
if(constant<=0)
{
System.out.println("function 1 -->f(x) = " + coef + "(" + a + ")" + constant);
System.out.println();
System.out.println("function 2 -->f(x) = " + coef + "(" + b + ")" + constant);
System.out.println();
System.out.println("function 3 -->f(x) = " + coef + "(" + c + ")" + constant);
System.out.println();
}
else
{
System.out.println("function 1 -->f(x) = " + coef + "(" + a + ")" + " + " + constant);
System.out.println();
System.out.println("function 2 -->f(x) = " + coef + "(" + b + ")" + " + " + constant);
System.out.println();
System.out.println("function 3 -->f(x) = " + coef + "(" + c + ")" + " + " + constant);
System.out.println();
}
double one;
one = coef * a + constant;
double two;
two = coef * b + constant;
double three;
three = coef * c + constant;
System.out.println("ANSWER:");
System.out.println();
System.out.println("Function 1 answer--> " + one);
System.out.println();
System.out.println("Function 2 answer--> " + two);
System.out.println();
System.out.println("Function 3 answer--> " + three);
System.out.println();
System.out.println("Graph");
System.out.println();
System.out.println("Should look like this");
System.out.println("x | y");
System.out.println();
System.out.println(a +" | " + one);
System.out.println();
System.out.println(b +" | " + two);
System.out.println();
System.out.println(c +" | " + three);
System.out.println();
System.out.println("The slope is: " + coef + "(remember the slope is understood over one.)");
System.out.println("The y-intercept is: " + constant);
}
}
