Simple factorial program in java using for loop

In the above program, unlike a for loop, we have to increment the value of i inside the body of the loop. Though both programs are technically correct, it is better to use for loop in this case.

It's because the number of iteration upto num is known. Course Index Explore Programiz. Java for Loop. Arrays in Java. Interfaces in Java. Java ArrayList. Popular Examples Check prime number.

I'm trying to compute the value of 7 factorial and display the answer, but when I tried to look up a way to do this I kept finding code that was written so that a number first had to be put in from the user and then it would factor whatever number the user put in.

But I already know what number I need, obviously, so the code is going to be different and I'm having trouble figuring out how to do this. Does anyone know how to do it correctly? You need to have two variables, one for the factorial calculation and other for the purpose of counter. Try this, i have not tested it but should work:.
