Java 18.3 Help

Question

Can someone help me with this? I dont get any Output. My Code: https://code.sololearn.com/cacF59fH6PnJ/?ref=app

Answer 1

// You take the input only one time. So works:
int number;
do {
number = scanner.nextInt();
switch(number) { // ….. and so on …

Answer 2

// this also works
switch(number = scanner.nextInt()) { // … and so on …

// but you necessarily need at the switch end this
default : ;
} // end of switch statement. Happy coding David .

Answer 3

But yet the while loop needs number but if i have it before and in it there is also an Error

Answer 4

You can't declare a variable more than one time. You have
int number;
And again in loop
int number = scanner.nextInt();

Just use in loop,
number = scanner.nextInt();

Answer 5

try input
1 2 3 4 0
