Labs

For this lab we will accept user input and use information about the ASCII characters.

1. Write a program to prompt the user for a String and check if the String meets certain conditions.
2. Use Scanner.nextLine() to read in a String that may contain spaces.
3. Check if all characters in an input String are letters (upper or lower) and print a messaging saying the result.
4. Some String methods you might use:
   • stringInstance.length() - get the length of the String.
   • stringInstance.charAt(i) - get the char at index i, which starts at 0 (like an array index).

(Solution: AlphaNumCheck.java)

1. Modify the program in (1) to see if the characters are alphanumeric (letters and numbers) or the space character.
