How to Convert Json date string to more readable date format?

JAVA QUESTION If a user enters a date of birth in m/d/yyyy format how do you display it in mm/dd/yyyy format?

• I have this code that is suppose to allow the user to either sort or search for what they input. It asks them first name, last name, and dob. However the code is suppose to be able to accept all types of date formats but when the sort or search if displayed it print the date in mm/dd/yyyy format. Here is what I have but I cant figure that one thing out. public static void main(String[] args) { int answer = 0; Scanner keyboard = new Scanner(System.in); System.out.println("How many people will you like to enter? "); int numPeople = keyboard.nextInt(); String firstName[] = new String[numPeople]; String lastName[] = new String[numPeople]; String dob [] = new String [numPeople]; for (int i = 0; i < numPeople; i++) { System.out.println("Enter first name, last name, and DOB in MM/DD/YYYY format : " ); firstName[i] = keyboard.next(); lastName[i] = keyboard.next(); dob[i] = keyboard.next(); } menuSelection(answer,firstName,lastName,… }//end main public static void menuSelection (int num, String [] firstName, String [] lastName, String [] dob){ Scanner keyboard = new Scanner (System.in); System.out.println(); System.out.println("\n" + "To search an entry enter 1. To sort a list enter 2. To exit enter 3: "); int answer = keyboard.nextInt(); if(answer == 1) { searchEntry(firstName,lastName,dob); } else if (answer == 2) { list(firstName,lastName,dob); } else { System.exit(0); } }//end menuSelection public static void searchEntry (String [] firstName, String [] lastName, String [] dob) { String name; int answer = 0; boolean flag; flag = false; Scanner keyboard = new Scanner (System.in); System.out.println("How will you like to search an entry? To search by First Name enter 1. " + "To search by Last Name enter 2. To search by Birth-date enter 3: "); int choice = keyboard.nextInt(); if (choice == 1) { System.out.println("Enter First Name to search: "); name = keyboard.next(); for ( int n = 0; n < firstName.length; n++) { if (firstName[n].equals(name)) { flag = true; System.out.println("You have searched for: " + firstName[n] + " " + lastName[n] + " " + dob[n] ); } } if (!flag) { System.out.println("Entry was not found"); } } else if (choice == 2) { System.out.println("Enter Last Name to search: "); name = keyboard.next(); for (int n = 0; n < lastName.length; n++) { if (lastName[n].equals(name)) { flag = true; System.out.println("You have searched for: " + firstName[n] + " " + lastName[n] + " " + dob[n] ); } } if (!flag) { System.out.println("Entry was not found"); } } else if (choice == 3) { System.out.println("Enter Birth-date to search: "); name = keyboard.next(); for (int n = 0; n < dob.length; n++) { if (dob[n].equals(name)) { flag = true; System.out.println("You have searched for: " + firstName[n] + " " + lastName[n] + " " + dob[n] ); } } if (!flag) { System.out.println("Entry was not found"); } } else { System.out.println("Input Error"); } menuSelection(answer,firstName,lastName,… }//end searchEntry public static void list (String [] firstName, String [] lastName, String [] dob){ int answer = 0; int ctr; int i;

• Answer:

  When you get the string that the user input, use the string functions to separate the string into the day month and year. It will then be easy to change it to the format you want then re-concatenate it before you add it into the array.
