Answer 1

Required Answer:-

Question:

• Find the output of the following códe snippet.

Output:

8, 7

Explanation:

Given códe snippet,

class Q2

{

public static void main()

{

int a=7;

int b=8;

a=a+b;

b=a-b;

a=a-b;

System.out.print(a+", "+b);

}

}

Here, we can see that,

a = 7 and b = 8 (initially)

a = a + b

Here, a is now equal to sum of a and b,

➡ a = 7 + 8

➡a = 15

a becomes 15

b = a - b

Here, b is now equal to difference of a and b,

➡ b = 15 - 8 (a = 15 and b = 8 before)

➡ b = 7

b becomes 7

a = a - b

Here, a is now equal to difference of a and b,

➡ a = 15 - 7 (a = 15 and b = 7 before)

➡ a = 8

a becomes 8

Hence,

a = 8

b = 7

System.out.print(a+", "+b);

Now, values of a and b are displayed in same line separated by comma.

Output: 8, 7

Answer 2

Output:

  8, 7

Given Snippet

   int a = 7, b = 8;

    a = a + b;

    b = a - b;

    a = a - b;

    System.out.print(a + ", " + b);

So, as a = 7 and b = 8,

  First,

      a = a + b or,

      a = 7 + 8

      a = 15

 Secondly,

      b = a - b, now as a is now 15, so,

      b = 15 - 8

      b = 7

Lastly,

      a = a - b, as b is now 7 and a is 15, so,

      a = 15 - 7

      a = 8

Finally, a = 8 and b = 7.
