Java Programming- Need the code- Suppose we have a string holding the text of an entire book. If we want to analyze segments of the text, it is inefficient to make substrings. Instead, we should just store a reference to the original text and the starting and ending positions. Design a class Segment that does this, and have it implement the CharSequence interface of the standard library. Write a test program in which you demonstrate that you can pass your Segment objects to methods that accept CharSequence instances, such as String.join and PrintStream.append.
In C++, create a class for a 3-dimensional array. To make it more general, allow the actual dimensionality to be 0d, 1d, 2d, or 3d. It should support indexing with operator(). If the programmer subscripts with fewer indices than you 'need' (0 for a 1d, 0 or 1 for a 2d, 0 or 1 or 2 for a 3d -- note that you can't under-subscript a 0d array), you should return the appropriately sized sub-array (of your class's type). (Note: This will require multiple overloads of operator() with different numbers of index arguments.) Since, as a template, math operations don't make sense, you'll have to for-go addition, etc. But you could use + and += for concatenation. Basically aligning the common dimensions of the two arrays and concatenating along the remaining dimension. (There can be only one for this to make sense. If there are none remaining, there are options for those kinds of things!) Make sure to overload it for proper dimensionality: Of course, you should also support input (the programmer…
