Write a Java program which defines and use unconstrained array of Strings of the length n (the value of n should be taken as users input). Fill in the array with Strings taken as a users input as well. The application should then display all elements of the initilaized array in a table-like format showing each element number and the string value stored in that element.

Use Scanner or JOptionPane as an input tool. The application should have three methods: 1) the main method where a user input of an array length n is accepted and an array is created; 2) InitializeArray method which takes the created array as a parameter, initialize array elements with users input and returns the array for the further use; 3) DisplayArray method which accepts the initialized array as a parameter, iterates through the its elements and displays the arrays content in a table-like format making use of JOptionPane. Compile, run and test your application.
