Question
What will be the output of the program?int x = 3; int y = 1; if (x = y) /* Line 3 */{ System.out.println("x =" + x); }x = 1x = 3Compilation fails.The code runs with no output.[#]
Solution
The program will fail to compile. This is because the condition in the if statement (x = y) is an assignment operation, not a comparison operation. In Java, the comparison operator is '==' not '='. So, the correct code should be:
int x = 3;
int y = 1;
if (x == y) {
System.out.println("x =" + x);
}
In the original code, the assignment operation (x = y) will always return the value of y, which is 1. Since 1 is considered as true in many programming languages, the if condition might be considered as true, but in Java, only boolean values can be conditions in if statements. Therefore, the code will not compile.
