Question

In Java

1. What will be the value of x after the following section of code executes:

int x = 3;

if (x > 3)

    x = x – 2;

else

    x = x + 2;

A. 1 B.3    C.5              D.7

2. What will be the value of y after the following section of code executes:

int y = 5, z = 3;

if (y > 4){

     z = 2;

     y = y – 1;

}else

     z = 1;

y = z;

A. 1 B.2    C.3              D.4

Answer 1

Thank you for asking the question.

1. Value of x after the given code executes is 5.

Explaination:- As initially x=3.Therefore else part will execute rather than "if part" because x is not greater than 3. So the final value of x is x=x+2 => 3+2=5. So,option c is correct.

2. Value of y after executing given code is 2.

Explaination:- As initially y=5 and z=3. Therefore y>4, that's why " if " part will execute.

So, on executing "if" part, z will be 2 and y=y-1 =>y=5-1=4.

At last, y=z and z is equal to 2. So , y is assigned as 2.

Correct answer is option B. 2
