Java Exercises: Print the values of x, y where a, b, c, d, e and f are specified

Java Basic: Exercise-214 with Solution

Write a Java program which solve the equation:
Print the values of x, y where a, b, c, d, e and f are given.


a,b,c,d,e,f separated by a single space.
(-1,000 ≤ a,b,c,d,e,f ≤ 1,000)

Sample Solution:

Java Code:

import java.math.BigDecimal;
import java.util.*;
public class Main{
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        ArrayDeque<Double> x = new ArrayDeque<Double>();
        ArrayDeque<Double> y = new ArrayDeque<Double>();
        System.out.println("Input the value of a, b, c, d, e, f:");
            int a = sc.nextInt();
            int b = sc.nextInt();
            int c = sc.nextInt();
            int d = sc.nextInt();
            int e = sc.nextInt();
            int f = sc.nextInt();             
            double t = (double)(d*c-a*f)/(d*b-a*e);
            double s = (double)(c-t*b)/a;
        int num = x.size();
        for(int i=0;i<num;i++){
            BigDecimal bdx = new BigDecimal(x.pollLast());
            BigDecimal bdy = new BigDecimal(y.pollLast()); 
            BigDecimal ansx = bdx.setScale(4, BigDecimal.ROUND_HALF_UP);
            BigDecimal ansy = bdy.setScale(4, BigDecimal.ROUND_HALF_UP);             
            System.out.printf("%.3f", ansx.doubleValue());
            System.out.print(" ");
            System.out.printf("%.3f", ansy.doubleValue());

Sample Output:

Input the value of a, b, c, d, e, f:
 5 6 8 9 7 4
-1.684 2.737

Previous: Write a Java program to check whether three given lengths (integers) of three sides form a right triangle. Print "Yes" if the given sides form a right triangle otherwise print "No".
Next: Write a Java program to compute the amount of the debt in n months. The borrowing amount is $100,000 and the loan adds 4% interest of the debt and rounds it to the nearest 1,000 above month by month.
