public void test(int x)
{
int odd = 1;
if(odd) /* Line 4 */
{
System.out.println("odd");
}
else
{
System.out.println("even");
}
}
Answer: Option
Explanation:
The compiler will complain because of incompatible types (line 4), the if expects a boolean but it gets an integer.

I am confused about it. At 4th Line if expects any value if it's equal to 0 than compilation will go in if condition otherwise else condition.

Using the integer 1 in the while statement, or any other looping or conditional construct for that matter, will result in a compiler error. This is old C Program syntax, not valid Java.

If condition take two value 1 and 0 ant 1=true 0=false.
Now I is int value which contain value 1 so it should be true.

Here if (odd) expects value of odd variable.
As declared earlier value of odd is 1 then condition holds true. Odd should be printed. Didn't understand why it is compiler error.

In C programming language while(1){} is a infinite loop. But in java while(1){} is a compilation error because in condition it expects either true of false(both keyword). So, the same c program equivalent code in java is while(true){} which represents infinite loop.

How it is a compile error?

In line 4. There is no Boolean condition. It just an integer. That's why it is compile error.

Hi guys,
Option A is the correct answer, because there should be a Boolean expression within the brackets followed by "if". Here is an integer number (Odd) within the brackets. That's why it's compile error.

In java the condition parameters are "true" and "false" i.e. in Boolean format.
But in C or C++ the positive integers are taken as true like.
If (500) // is taken as true in C language. So, Don't be confuse the feature of java and C.
