Post-increment operator

[Aakash Chandel]

package inc;

public class IncrementDemo {
    
    public static void main(String[] args) {
        IncrementDemo demo = new IncrementDemo();
        int i = 0;
        i = i++; 
        System.out.println(i); //prints 0
        int a = i++;  
        System.out.println(i); //prints 1
        System.out.println(a); //prints 0
    }
    
}

The output of the above code is : 0 1 0 which flattened my understanding about post-increment operators.

Why the output of the above program is not 1 2 1 ?

Can anybody give some insight on this ?
