Write a method called fact that recursively calculates the factorial value of its single int parameter. the value returned by fact is a long ..

The program to this question can be given as follows:

Program:

//class

public class factorial //defining class

{

//method fact

public static long fact(int x1) //defining method fact

{

//conditional statement

if (x1 <= 1) //if block checks parameter value less then equal to 1

{

return 1; //return value

}

else //else part

{

return (fact(x1 - 1) * (long) x1); //return factors using recursive function

}

}

//method main

public static void main(String[] args) //defining main method

{

long data=fact(5);//defining variable that holds function value

System.out.println("Factorial is: "+data); //print value

}

}

Output:

Factorial is: 120

Explanation:

In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.

ok that sounds like a app that my brother would like

the answer is a   : ) hope that
