Post and Pre increment operators

Question

When i run the following example i get the output 0,2,1

class ZiggyTest2{

        static int f1(int i) {  
            System.out.print(i + \",\");  
               


        

Answer 1

In Post increment operator value will of operand will increase after use. Example

int k =1;
        int l = k++;
        System.out.println("...k..."+k+"...l.."+l);

First k (value = 1) is assigned with l after that the k value will increase

Similarly thing happens in the following line

i = i++ + f1(i);
