Question
Does the method call in the following method cause compile errors?
public static void main(String[] args) {
Math.pow(2, 4);
}
Group of answer choices
- Yes
- No
Solution
Yes, the method call in the following method does cause compile errors. The reason is that the Math.pow(2, 4) method call is not assigned to any variable or used in any way. The Java compiler expects that the result of a method call is used in some way, either assigned to a variable, used in a larger expression, printed out, etc. Since the result of Math.pow(2, 4) is not used, the Java compiler will give an error.
To fix this error, you could assign the result of Math.pow(2, 4) to a variable, like this:
public static void main(String[] args) { double result = Math.pow(2, 4); }
Or you could print out the result, like this:
public static void main(String[] args) { System.out.println(Math.pow(2, 4)); }
