Question

(ii) if-else-if construct into switch case
if(var==1)
System.out.println("Distinction");
else if(var==2)
System.out.println("First Division");
else if(var==3)
System.out.println("Second Division");
else
System.out.println("invalid");​

Answer 1

Program:

switch(var){

     Case 1: System.out.println("Distinction");

                  break;

     Casa 2: System.out.println("First Division");

                   break;

     Case 3: System.out.println("Second Division");

                   break;

     default: System.out.println("Invalid");

                   break;

}

Explanation:

When ever you use a use a switch-case you have to write"break" for every case you write, because if that case is true it will print the following code and checks whether break is there or not if there it will break the while loop if not it will go to next true case and prints those lines too
