Solution 1

Your answer would be d.

7 is first converted to an integer.
7 is then implicit y converted to a string and concatenated to 5 thus giving you 75 as a string.
This is then again converted to an integer thus giving you integer 75.

God bless you. I was thinking completely different way.
so the last stage is D where converted to Integer from String or last stage is String converted from integer which is C

I would recommend you run this line in Java and check the output.

I could not examine the code by following because error message can't cast String to int
public static void printnum1() {

int i;

i = ((int)((string)((int)"7")+"5"));

System.out.println(i);
}

In that case, this question is wrong and you will get an compile error.
