Discussion Forum : Operators and Assignments - Finding the output (Q.No. 5)
5.
What will be the output of the program?
class Equals
{
public static void main(String [] args)
{
int x = 100;
double y = 100.1;
boolean b = (x = y); /* Line 7 */
System.out.println(b);
}
}
Answer: Option
Explanation:
The code will not compile because in line 7, the line will work only if we use (x==y) in the line. The == operator compares values to produce a boolean, whereas the = operator assigns a value to variables.
Option A, B, and D are incorrect because the code does not get as far as compiling. If we corrected this code, the output would be false.

Here we compare double and an integer values. They are not equal so the output false. And we can assign double value to int value by using typecasting that is;
x= (int) y; it is called narrowing.
x= (int) y; it is called narrowing.

We can't assign double value to int.

@Anshulwall.
I don't know what o/p will give in Linux, but in windows o/p will be false because the data type is boolean.

Yes the answer is correct as you can't assign a double to int.

I think double does not take float value and only 100 takes and equalizes and so the result comes as 1.

The answer C is correct, but also because you cannot assign a double value to an int.

It will give output false. Because they are not equal and compared in doubles. So it can't give output 1.

class Equals
{
public static void main(String [] args)
{
int x = 100;
double y = 100.1;
boolean b = (x == y);
System.out.println(b);
}
}
on linux o/p is: 1
Can anyone explain?
{

boolean b = (x == y);

The above code is correct and will produce output : false
{
public static void main(String [] args)
{
int x = 100;
double y = 100.1;
boolean b = (x == y); /* Line 7 */
System.out.println(b);
}
}
The above code is correct and will produce output : false
