Question

Design a class overloading a method calculate() as follows:

1. void calculate(int m, char ch) with one integer argument and one character argument. It checks whether the integer argument is divisible by 7 or not, if ch is 's', otherwise, it checks whether the last digit of the integer argument is 7 or not.
2. void calculate(int a, int b, char ch) with two integer arguments and one character argument. It displays the greater of integer arguments if ch is 'g' otherwise, it displays the smaller of integer arguments. 

Answer 1

// Execute the sampleMethod 
import java.util.*;
class FQ18
{
void calculate(int m, char ch)
{
if (ch == 's') 
{ if (m % 7 == 0) 
System.out.println("The number is divisible by 7");
else
System.out.println("The number is not divisible by 7");
}
else
{if (m % 10 == 7)
System.out.println("The last digit of the number is 7");
else
System.out.println("The last digit of the number is not 7");
}}

void calculate(int a, int b, char ch)
{if (ch == 'g') System.out.println("The greater number is " + Math.max(a, b));
else System.out.println("The smaller number is " + Math.min(a, b));
}
public static void sampleMethod()
{FQ18 mm = new FQ18();
Scanner ob = new Scanner(System.in);
int x, y;
char ch;

System.out.println("Enter the two numbers");
x = ob.nextInt();
y = ob.nextInt();
System.out.println("Enter a character....'g' for greater value");
ch = ob.next().charAt(0);
mm.calculate(x, y, ch); // Method Call .....int, int, char

System.out.println("\n\nEnter a number");
x = ob.nextInt(); 
System.out.println("Enter 's' for divisibility by 7(or)any char for last digit 7");
ch = ob.next().charAt(0);
mm.calculate(x, ch); // Method Call ...int, char 
}}
