Answer 1

Replace sc.next() with sc.nextLine()

Answer 2

Remove the semicolon after if() in line 19. It's not easy to understand what your code does without any comments and "reasonable" variable names. What is cn? What is p? It's also quite difficult to read because of its lack of indentation. You don't have to use indentation in languages like Java, but it's easier to read like this:

for () {
if() {
while() {
/* do something */
}
}
}

It's helpful if you try to debug your code too.

Answer 6

https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html

This may help too. Being able to read and understand documentation is really useful to a programmer

Notice the 'delimiter' options - this will be useful for your first code as you can delimit by spaces (which is what your if statement is doing) so this will make your code neater because it's delegating the task to another class

Answer 7

as Dan Walker said indent your programs properly so that it's easier for you as well as others to read and understand.
