Java: 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

Java: Tips of the Day


Removes elements in an array until the passed function returns true. Returns the remaining elements in the array.

Loop through the array, using Arrays.copyOfRange() to drop the first element of the array until the returned value from the function is true. Returns the remaining elements.

public static int[] dropElements(int[] elements, IntPredicate condition) {
    while (elements.length > 0 && !condition.test(elements[0])) {
        elements = Arrays.copyOfRange(elements, 1, elements.length);
    return elements;
