If you're talking about factorial as in "4! = 4 * 3 * 2 * 1 = 24" then you could make a function something like this:
public int fact(int Num) {
int fact;
for (int i = Num; i > 1; i--) {
fact = i * (i - 1)
}
Return fact;
}
It's been a little while since I've learned Java, but the exclamation point used to denote factorials (!) is already used in Java to denote a negation (e.g. a != 2 means a is not equal to 2). To create a factorial in Java, construct a for loop and multiply all the consecutive integers.
A Program in Java that spawns multiple threads is called a multithreaded program in Java.
// Iterative solution public static final long iterativeFactorial(final long n) { long factorial = 1; for (long i = 1; i <= n; i++) { factorial *= i; } return factorial; } // Recursive solution public static final long recursiveFactorial(final long n) { if (n <= 1) { return n; } return n * recursiveFactorial(n - 1); } // Arbitrary length solution - may take a while, but works on any positive number. public static final BigInteger factorial(final BigInteger n) { BigInteger factorial = BigInteger.ONE; for (BigInteger i = BigInteger.ONE; i.compareTo(n) <= 0; i = i.add(BigInteger.ONE)) { factorial = factorial.multiply(i); } return factorial; }
That refers to the program that runs the compiled Java program.
Q.1 Write a program to print first ten odd natural numbers. Q.2 Write a program to input a number. Print their table. Q.3 Write a function to print a factorial value.
write a java program to find factorial using recursive and non recursive
An example in Java, to compute 10!: int factorial = 1; for(int i = 1; i < 11; i++) { factorial *= i; }
I suggest to use a for loop, more or less like this (assuming the parameter is "n"): product = 1; for (int i = 1; i <= n; i++) { product *= i; }

In Prolog, a simple factorial program can be defined using recursion. Here's a basic implementation: factorial(0, 1). % Base case: factorial of 0 is 1 factorial(N, Result) :- N > 0, N1 is N - 1, factorial(N1, Result1), Result is N * Result1. % Recursive case You can query the factorial of a number by calling factorial(N, Result). where N is the number you want to compute the factorial for.

Any program written for the Java technology needs Java. Any program NOT written for Java DOESN'T need it.
this is a code for calculating it recursivelly: float Factorial (float n) { if (n<=1) return 1.0; else return n* Factorial(n-1); }
