Switch Statement Help

[bluegreen7hi]

Alrighty, so I have to do this assignment for my Java course, using a switch statement. The assignment is to have the user enter a number (1-5), and have the corresponding line of a poem be displayed. So if the user entered 1, "One two, buckle your shoe" would be displayed. This is what I have and it's giving me a huge problem:

Code:

import java.util.Scanner;

public class Poem
{
	public static void main(String[] args);
		
		Scanner kboard = new Scanner(System.in);
		System.out.println("Enter a number 1-5 (or 0 to quit).");
		int n = kboard.nextLine();
		

		switch (n) {
			case 1: System.out.println("One two, buckle your shoe.");
			break;
			case 2: System.out.println("Three four, shut the door.");
			break;
			case 3: System.out.println("Five six, pick up sticks.");
			break;
			case 4: System.out.println("Seven eight, lay them straight.");
			break;
			case 5: System.out.println("Nine ten, a big fat hen.");
			break;
			default: System.out.println("Goodbye.");
			break;
			
			
		}
	}			
}

This is giving me a HUGE string of errors. (Something like 45). I'm wracking my brain here trying to figure this out. Any help is greatly appreciated. Thanks!

Have a look at the fifth line in your code - there is an error there, for one.

Well now all I'm getting is this for errors:


--------------------Configuration: <Default>--------------------
C:\JavaPrograms\Poem.java:8: <identifier> expected
System.out.println("Enter a number 1-5 (or 0 to quit): ");
^
C:\JavaPrograms\Poem.java:8: illegal start of type
System.out.println("Enter a number 1-5 (or 0 to quit): ");
^
C:\JavaPrograms\Poem.java:12: illegal start of type
switch (n) {
^
C:\JavaPrograms\Poem.java:12: <identifier> expected
switch (n) {
^
C:\JavaPrograms\Poem.java:14: orphaned case
case 1: System.out.println("One two, buckle your shoe.");
^
C:\JavaPrograms\Poem.java:30: class, interface, or enum expected
}

Not sure what's wrong in the fifth line also.

Please show what you changed.

While you're at it, you need to understand this line:

Code:

...
        int n = kboard.nextLine();
...

See the API for Scanner, you're attempting to use the method nextLine() which returns a String but you're really trying to return an int, based on the variable you're trying to set(int n). Do you see a method in the API that will return that int for you?

How do we terminate statements.. ? We do this with the ; operator, However in your case you look like you are at the beginning of a block - therefore you need the { operator. Not unlike what you corrected in the switch(n); line.

int n=kboard.nextInt();

Try this one...

CNU, that was meant for the OP to figure out. If they post back that they're having considerable difficulty then it's probably OK to post what you posted, but doing this too soon doesn't help them, especially giving the flat-out answer. Something to consider.
