First of all, my mother language is not English.

Now I study Increment(++) ande Decrement(–) operators of Java.
I tried an issue. But the result of mu code differents from my expectation.

Issue

• Assign an integer to x.
• Using Increment(++) ande Decrement(–) operators and showing x.

My code
I wrotea code like this ;

public class Main{
    public static void main(String[] args){
        int x = 19;
        int inc = x++;
        int dec = x--;

        System.out.println(inc);
        System.out.println(dec);

    }
}

My Expectation
I expected the result will be “20” and “19”.

Result
However, running result was “19” and “20”.
I still can’t understand why the result was “19” and “20”.

The thing I want to know

1. Why the result of running my code was “19” and “20”.
2. If the result of running my code will be “20” and “19”, where should I fix my code?
