The program you are going to write will produce Strings representing 1D, 2D, and 3D String arrays. You will also need to add at least 1 additional test in each of testArrToString1D and testArrToString2D. You are encouraged to complete the methods in the roughly order given, as the arrToString and arrInBox methods should use the other methods. The order should be something like:lineOf, endWith, arrToString(String[])arrToString(St ring[][])arrToString(String[][][])a rrInBoxAttached documents:NestedPrinting. java/*** A class that can be used to build String representations of 1D, 2D, and 3D String arrays* to display their contents.*/public class NestedPrinting {
