It may help to post your code here, or explain what you think the answer might be.

I could answer this with a simple "An if statement means you can check to see if a condition is true, and if it is, execute a block of code" but I'm not entirely sure you're asking what an if statement is, or if you're asking for help with a particular exercise, or if you're having trouble particularly with the way logical operators like &&, ||, or some sort of XOR operator work.

Check out the Tips for asking questions on the right-hand side of the page, which will give details on how to post your code in the forums when you're asking for help. Good luck!

An if statement checks a condition and if the condition is true, it runs the code.

Conditions can be 'True' or 'False'. We are checking if something is true or not true.

Say we had a variable called Monday.

dayOfTheWeek = Monday

We can use an if statement to see if today is Monday. If it is Monday, we want to do some special code.

// Check if today is Monday. If it is, print out "It's Monday!"
if (dayOfTheWeek == Monday) {
    print("It's Monday!")
}

We can also check for true and false other ways too.

Say we had a number that equaled 5.

int number = 5

We can check to see if the number is greater than 0, which should be 'true'. If it is true, we want to tell the user.

The first if statement will run, because 5 is greater than 0 (true) and the second if statement will not run because 5 is not less than 0 (false).

if(number > 0) {
    print("The number is greater than 0!");
}

if(number < 0) {
    print("The number is less than 0!");
}

I hope that is a little clearer, if it's not, feel free to reply and I can try to explain more or give more examples. It's one of those things where the more you do it, the more you will become better at it.

I was going to answer something like this, but I noticed the post came from an exercise on logical OR operators, and thought maybe that was the sticking point. Great answer!

Thanks, but in some video's i just don't understand some things because i'm dutch. And you know dutch people aren't that good in english!

But thanks for your reply!
