The following exercise assesses your ability to do the following:Utilize abstraction to deconstruct a complex problem into individual tasks.Utilize methods in a programming solutionDefine methods using appropriate Java syntax1.Read this document carefully and review the rubric for this assignment before beginning work. Be sure you are familiar with the criteria for successful completion. The rubric link can be found in the digital classroom under the assignment.2.In this assignment you are designing the following methods by creating flowcharts and writing the method signature. You are not writing code for this assignment.a.A method that takes a String and returns true if the String has 13 digits and false otherwise.a("123456789012")falsea("1234567890123")trueb.A method that takes a String of 13 digits creates and returns an array of ints with 13 positions. The array should contain the integer equivalents of the digits in the original string.b("1234567890123") arr{1,2,3,4,5,6,7,8,9,0,1,2,3}b("9781623363581") arr{9,7,8,1,6,2,3,3,6,3,5,8,1}c.A method that takes an array of 13 ints and returns an array of 13 ints that is computed as follows:i.Digits at even index locations in the original array are copied directly to the return array at corresponding positionsii.Digits at odd index locations in the original array are multiplied by 3 and copied to the return array at corresponding positions.c(arr{1,2,3,4,5,6,7,8,9,0,1,2,3})arr{1,6,3,12,5,18,7,24,9,0,3,2,3}c(arr{9,7,8,1,6,2,3,3,6,3,5,8,1})arr{9,21,8,3,6,6,3,9,6,9,5,24,1}d.A method that takes an array of 13 ints and calculates and returns the sum of the first 12 ints in the arrayd({1,6,3,12,5,18,7,24,9,0,3,2,3})90d({9,21,8,3,6,6,3,9,6,9,5,24,1})109e.A method that takes the sum calculated in part d and the last value in the integer array and returnsi.True if the sum and the last integer are both 0ii.True if (10 - (sum%10)) is equal to the last integeriii.False otherwisee(90,3)falsee(109,1)truef.Create a flowchart for a solution that:i.reads in strings of digits from a fileii.calls the methods you've designed to determine whether or not each string of digits has the desired propertyiii.outputs each string of digits that satisfies the property, one per line.3.Create a video in which you present your method signatures and flowcharts. Videos over 5 minutes in length will not be accepted.4.Submit the following:a.A .png file containing the requested method signatures and flowchartsb.A link to your videoSample method signature and flowchart for method a:
