See more:

Implement the factorial method for the given parameter n. Remember that 4!= 4*3*2*1. Use a for loop.

Java

public int p02Factorial(int n) {
  return 0;

Can someone walk me through how to do this?

What I have tried:

public int p02Factorial(int n) {
return 0;

This is not a question, despite two question marks.
What you have tried won't even compile. This is not a decent effort. I doubt anyone would waste time for you, because it's hard to be sure that you would be able to use help.

NO, this is your HomeWork, not ours.
You already know everything, the only thing left is writing the code.
Think about what you have been teached.
If really you can't find a solution yourself, speak with your teacher.

Is it really that hard to look up your textbook to see what a for loop looks like ? I'll help you ...

Java

for (initialisation; termination; increment) 
{
    // statement(s) here
}

your issue is picking values for initialisation, termination, increment, as well as something useful for 'statement(s)'

So, given you're going to have some parameter value 'n', what do you think is a good bet for 'initialisation', hmmm ? what if I said, initialisation looks like

Java

for (int intMultiplier = n; termination; increment)
{
    // statement(s) here
}

is that enough to start with ?
