(I understand there may be some errors in my code, but I have only really just begun Java. java takes an integer between 0 and 6 as a command-line argument and uses a switch statement to print the corresponding name of the day (Sunday to Saturday).

At the moment the program asks the user once and then it is finished, however I want the user to be able to input as many animals as they'd like and get appropriate responses.

The way its written below Eclipse gives me an error and won't let me use switch (n) on the second statement in the for loop. The user inputs a given animal and the system outputs the necessary noise that relates to the animal. You can use statements such as if, if-else, switch, for, and while to declare variables and specify expressions, make decisions, iterate (or loop) over statements, break and continue iteration.

Normally, if we have to choose one case among many choices, nested if-else or else if is used. If there is a match, the associated block of.
