Question

In Java Programing

write two classes:

1.)

The first is a class called LinearEquation that stores two linear equations.

ax + by = e

cx + dy = f

x = (ed - bf) / (ad - bc)

y = (af-ec) / (ad - bc)

It should have:

Private data fields a, b, c, d, e and f

Constructor that takes in arguments for a through f.

Six getter methods for a, b, c, d, e, and f

A method named isSolvable() that returns true if a*d - b*c is not 0.

Methods getX() and getY() that return the solution for the equation.

this class should include a UML diagram

2.) Second, write a test program (class) that prompts the user for the six values and report if the equation has a solution. If so, display the solution.

Explanation / Answer

SolveEquations.java

public class SolveEquations {

//Declaring instance variables
private double a;
private double b;
private double c;
private double d;
private double e;
private double f;

//Parameterized constructor
public SolveEquations(double a, double b, double c, double d, double e, double f) {
this.a = a;
this.b = b;
this.c = c;
this.d = d;
this.e = e;
this.f = f;
}

//getters and setters
public double getA() {
return a;
}

public void setA(double a) {
this.a = a;
}

public double getB() {
return b;
}

public void setB(double b) {
this.b = b;
}

public double getC() {
return c;
}

public void setC(double c) {
this.c = c;
}

public double getD() {
return d;
}

public void setD(double d) {
this.d = d;
}

public double getE() {
return e;
}

public void setE(double e) {
this.e = e;
}

public double getF() {
return f;
}

public void setF(double f) {
this.f = f;
}

public boolean isSolvable() {
if ((a * d - b * c) != 0)
return true;
else
return false;
}
public double getX() {
return (e * d - b * f) / (a * d - b * c);
}
public double getY() {
return (a * f - e * c) / (a * d - b * c);
}

}

Test.java

import java.util.Scanner;

public class Test {

public static void main(String[] args) {

//Declaring variables
double a, b, c, d, e, f, x, y;

/*
* Creating an Scanner class object which is used to get the inputs
* entered by the user
*/
Scanner sc = new Scanner(System.in);

//Getting the input entered by the user
System.out.print("Enter a:");
a = sc.nextDouble();
System.out.print("Enter b:");
b = sc.nextDouble();
System.out.print("Enter c:");
c = sc.nextDouble();
System.out.print("Enter d:");
d = sc.nextDouble();
System.out.print("Enter e:");
e = sc.nextDouble();
System.out.print("Enter f:");
f = sc.nextDouble();

//Creating an instance of SolveEquations class
SolveEquations se = new SolveEquations(a, b, c, d, e, f);

//Based on the equations is solvable or not displaying the solutions
if (se.isSolvable()) {
System.out.println("X = " + se.getX());
System.out.println("Y = " + se.getY());
} else {
System.out.println(":: Equations has no solutions ::");
}

}

}

Output:

Enter a:2
Enter b:4
Enter c:6
Enter d:6
Enter e:2
Enter f:1
X = -0.6666666666666666
Y = 0.8333333333333334
