Question

Java programming:

The following java code is supposed to solve a linear equation of the form aX+b = 0

where a and b are real numbers. However, there are some errors, nd and x them using a

combination of exceptions and control statements. Hint. What could go wrong in the execution

of this program?

/*********************************************/

// here is the code I have:

import java.util.*;

public class Solver{

public static void main(String[] args){

System.out.println("Let us solve an equation of the form aX + b = 0 with a and

b real numbers.");

Scanner in = new Scanner(System.in);

System.out.println("Enter a:");

double a = in.nextDouble();

System.out.println("Enter a:");

double b = in.nextDouble();

double x = -b / a;

System.out.println("The solution to this equation is: " + x);

}

}

import java.util.*;

public class Solver{

    public static void main(String[] args){

        System.out.println("Let us solve an equation of the form aX + b = 0 with a and b real numbers.");

        Scanner in = new Scanner(System.in);

        System.out.println("Enter a:");

        double a = in.nextDouble();

        System.out.println("Enter b:");

        double b = in.nextDouble();

        double x;
        if(a!=0) {
            x = -b / a;
            System.out.println("The solution to this equation is: " + x);
        }
        else
            System.out.println("Value of a should not be zero");

    }
