Given:
public class Test {
public static void main(String[] args) {
int day = 1;
switch (day) {
case "7": System.out.print("Uranus");
case "6": System.out.print("Saturn");
case "1": System.out.print("Mercury");
case "2": System.out.print("Venus");
case "3": System.out.print("Earth");
case "4": System.out.print("Mars");
case "5": System.out.print("Jupiter");
}
}
}
Which two modifications, made independently, enable the code to compile and run?
- Adding a break statement after each print statement
- Adding a default section within the switch code-block
- Changing the string literals in each case label to integer
- Changing the type of the variable day to String
- Arranging the case labels in ascending order
Answer(s): A,C
Explanation:
The following will work fine:
public class Test {
public static void main(String[] args) {
int day = 1;
switch (day) {
case 7: System.out.print("Uranus"); break;
case 6: System.out.print("Saturn"); break;
case 1: System.out.print("Mercury"); break;
case 2: System.out.print("Venus"); break;
case 3: System.out.print("Earth"); break;
case 4: System.out.print("Mars"); break;
case 5: System.out.print("Jupiter"); break;
}
}
}
