Question Question 35
Write a complete Java program that invokes a function satis() to find whether four integers a, b, c, d sent to satis( ) satisfy the equation a3 + b3 + c3 = d3 or not. The function satis( ) returns 0 if the above equation is satisfied with the given four numbers otherwise it returns -1.
import java.util.Scanner;
class KboatCheckEquation
{
int satis(int p,
int q,
int r,
int s) {
int res;
double lhs = Math.pow(p,3)
+ Math.pow(q,3)
+ Math.pow(r,3);
double rhs = Math.pow(s,3);
if(lhs == rhs)
res = 0;
else
res = -1;
return res;
}
public static void main(String args[])
{
KboatCheckEquation obj = new KboatCheckEquation();
Scanner in = new Scanner(System.in);
System.out.print("Enter a: " );
int a = in.nextInt();
System.out.print("Enter b: " );
int b = in.nextInt();
System.out.print("Enter c: " );
int c = in.nextInt();
System.out.print("Enter d: " );
int d = in.nextInt();
int res = obj.satis(a, b, c, d);
if(res == 0)
System.out.println("Equation satisfied");
else
System.out.println("Equation not satisfied");
}
}Output
