Discussion :: Flow Control - Finding the output (Q.No.12)

12.

What will be the output of the program?

int x = 3; 
int y = 1; 
if (x = y) /* Line 3 */
{
    System.out.println("x =" + x); 
}

[A].	x = 1
[B].	x = 3
[C].	Compilation fails.
[D].	The code runs with no output.

Answer: Option C

Explanation:

Line 3 uses an assignment as opposed to comparison. Because of this, the if statement receives an integer value instead of a boolean. And so the compilation fails.

== are use to compare to int .equal are use to compare objects

Here should be use comparisation operator. We can't assign the value within the if () statement.

In C with IF statement, we can perform this assignment operation. Will this rule not work in java ?

Answer is D because the code runs with no output.
