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:
ax+by=c
dx+ey=f
Print the values of x, y where a, b, c, d, e and f are given.
Input:
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;
x.push(s);
y.push(t);
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());
System.out.println();
}
}
}
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.

Java: Anagrams
Generates all anagrams of a string.
public static List<String> anagrams(String input) { if (input.length() <= 2) { return input.length() == 2 ? Arrays.asList(input, input.substring(1) + input.substring(0, 1)) : Collections.singletonList(input); } return IntStream.range(0, input.length()) .mapToObj(i -> new SimpleEntry<>(i, input.substring(i, i + 1))) .flatMap(entry -> anagrams(input.substring(0, entry.getKey()) + input.substring(entry.getKey() + 1)) .stream() .map(s -> entry.getValue() + s)) .collect(Collectors.toList()); }
