Question
Which of the following will compile when inserted in the following code? (Choose all that apply)public class Order3 { final String value1 = "1"; static String value2 = "2"; String value3 = "3"; { // CODE SNIPPET 1 } static { // CODE SNIPPET 2 }}*A. value1 = "d"; instead of // CODE SNIPPET 1B. value2 = "e"; instead of // CODE SNIPPET 1C. value3 = "f"; instead of // CODE SNIPPET 1D. value1 = "g"; instead of // CODE SNIPPET 2E. value2 = "h"; instead of // CODE SNIPPET 2F. value3 = "i"; instead of // CODE SNIPPET 2
Solution
The correct options are:
B. value2 = "e"; instead of // CODE SNIPPET 1 C. value3 = "f"; instead of // CODE SNIPPET 1 E. value2 = "h"; instead of // CODE SNIPPET 2
Explanation:
A. value1 = "d"; instead of // CODE SNIPPET 1 - This will not compile because value1 is declared as final. A final variable in Java can only be assigned once.
D. value1 = "g"; instead of // CODE SNIPPET 2 - This will not compile because value1 is declared as final. A final variable in Java can only be assigned once.
F. value3 = "i"; instead of // CODE SNIPPET 2 - This will not compile because value3 is a non-static variable and cannot be referenced from a static context.
B, C, and E will compile because value2 is a static variable and can be assigned in both static and non-static blocks, and value3 is a non-static variable and can be assigned in a non-static block.
