Java OCA OCP Practice Question 102

Question

What is the result of compiling and executing the following class? 

package sports; //from w  ww. j  a v  a 2 s.co m
public class MyClass { 
        String color = "red"; 
        private void printColor(String color) { 
           color = "purple"; 
           System.out.print(color); 
        } 
        public static void main(String[] rider) { 
           new MyClass().printColor("blue"); 
        } 
}
  • A. red
  • B. purple
  • C. blue
  • D. It does not compile. 


B.

Note

First off, the color variable defined in the instance and set to red is ignored in the method printColor() as local scope overrides instance scope, so Option A is incorrect.

The value of color passed to the printColor() method is blue, but that is lost by the assignment to purple, making Option B the correct answer and Option C incorrect.

Option D is incorrect as the code compiles and runs without issue.
