Answer 1

Answer:Convert the following if else if construct into switch case

Explanation:

By using switch statement instead of if else if construct

switch(var)

{

          case 1:

                System.out.println("good");

                break;

          case 2:

                System.out.println("better");

                break;

          case 3:

                System.out.println("best");

                break;

          default:

                System.out.println("Invalid");

}        

Note

If user need to choose one case among several choices, nested if-else can be used but when number of choices become large, then switch..case is considered as better option as program will be more easier to understand.
