What do these beginner terms mean

Question

I have no idea, I am not even in calculus yet. I heard el means expression language. I do not know what colons are used for. Also, the for loop is used for what?

I'm VERY new...

Answer 1

I am not familiar with Java but I bet that the question about for loop can be directed to any language.

A process changes its variables at a time so you need to check this change using for loop for instance.

Let me tell you that I was born now so I am zero years old. (y=0)
It so sad but my destiny is die 1 second before I am 20. That means that I will be alive for 20 whole years (y<20)
Every year I get older by one year (y++)

for(y=0; y<20; y++) {
I am still alive. I am {y} year(s) old.
}

My life cannot continue after 20th birthday because it is not my destiny.

Hope it is not complicated.

Answer 2

Study for loops again. I believe there is a category in the Java course just for for loops, also take a look on the internet if you don't get it.
