Question

Give output of the following Java program:
Int k=5; j=9;
k+=k++-++j+k;
Sopln(k+""+j);

Answer 1

Answer:

The ans is 6

Explanation:

we can simply the syntax to help us understand.

int k = 5, j = 9;

k = k + ((k++)-(++j)+k);

Sopln(k+""+j);

.

.

x++ = interpreter will execute the statement first and then increment the variable

++x = interpreter will increment the variable, and then execute the statement with the new values...

k = 5, j = 9

1.  (k++)

2.  -(++j)

3.  +k

1. k is still 5, its value is passed on and then incremented to 6

5 + -(++j)+k

2. j is incremented and the value is passed on

5 - 10 + k

3. k is 6 (changed in step 1), and the value is passed on...

5 - 10 + 6

-5 + 6

1

now we see the whole thing was being added to the old value of k(old value is 5)

k = k + 1

k = 5 + 1

Therefore k is now 6

I hope you understood, English is not my primary language
