15.4: Emails Again

Write a method with the following signature:

public static boolean validEmail(String str) 

• The method returns a boolean value for whether the email is valid 

• Hint: You've done this same thing on your previous assignment, just not with a method.
• For this assignment we are going to "outsource" the work of determining whether an email contains an '@' to a method named validEmail.

• Copy and paste the starter code inside the {} of a class named Email2. This method can be placed either above or below the main method:

public static boolean validEmail(String str) { //add the code for your method here }

• Cut the for loop from main and paste it inside the {} of the method.
  • Note: Do not call the contains() method or you will get no credit for this assignment. You must use a for loop to detect the '@' symbol.
• Verify that your new version of the program still works identically to Assignment 13.3
