Question

Q1: Re-write following if-else-if statements as Switch statement. Your final code should result in the same output as the original code below.

if (selection == 10)

System.out.println("You selected 10.");

else if (selection == 20)

System.out.println("You selected 20.");

else if (selection == 30)

System.out.println("You selected 30.");

else if (selection == 40)

System.out.println("You selected 40.");

else System.out.println("Not good with numbers, eh?");

Q2:

Re-write following while loop into Java statements that use a Do-while loop. Your final code should result in the same output as the original code below.

int total = 0;

while(total<100)

{

System.out.println("you can still buy for"+(100-total)+"Dollars");     

total=total+5;

}

Q1:
switch(selection){
    case 10:
        System.out.println("You selected 10.");
        break;
    case 20:
        System.out.println("You selected 20.");
        break;
    case 30:
        System.out.println("You selected 30.");
        break;
    case 40:
        System.out.println("You selected 40.");
        break;
    default:
        System.out.println("Not good with numbers, eh?");
}


Q2:
int total = 0;
do
{
    System.out.println("you can still buy for"+(100-total)+"Dollars");     
    total=total+5;
}while(total<100);
