Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
True or False: The String class’s replace method can replace individual characters, but cannot replace substrings.
StringBuilder objects should be used in place of String objects if
O is more than 80 characters long.

- Name format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file.

Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. This process is illustrated in the following example: Step 1. Enter the ticket number; for example, 123454. Step 2. Remove the last digit, leaving 12345. Step 3. Determine the remainder when the ticket number is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4. Assign the Boolean value of the comparison between the remainder and the digit dropped from the ticket number. Step 5. Display the result—true or false—in a message box. Accept the…arrow_forward
