Question 125 / 297: What is the result of compiling and running the following code?

public class Tester {

	static void test(float x) {
		System.out.print("float");
	}

	public static void main(String[] args) {
		test(99.9);
	}
}

A float

B Compilation fails

C An Exception is thrown at run time

<< First < Previous Next > Last >>

Explanation:

floating-point numbers are by default of type double.

99.9 is a double not a float

The compiler will complain because it cannot find a method named test() that can accept a double.
