- PS: Please answer number 1 and 2 as they are all linked altogether with the subparts by following the instructions perfectly and not confusing. Write a Java Program with an intentional error in it. 1. Your program must include Loops and Arrays with a breakpoint 2. Once you have created your program, debug the application in eclipse to fix the error. a. Ensure that you take at least 3 screenshots of the debugging process and provide a brief explanation of the step. b. Ensure you use breakpoints and submit a snapshot labelling it. c. Submit all steps.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.Answer all the questions else downvote and bad rating a). What is the difference between shallow and deep equality tests on Arrays in Java? (b) How would you backup (copy) all elements of an array to a new array using a *single* Java statement? (c) Provide an algorithm/pseudocode for finding the penultimate (second-last) node in a doubly linked list where the last node is indicated by a null next reference. (d) Provide an algorithm/pseudocode to find the ?th last element of a singly linked list starting with only the header sentinel? (e) Which function has the similar profile (i.e., the same “shape”) in the log-log scale as it is in the classical y/x scale? (f) How does one order these functions based on non-increasing asymptotic growth rates? (g) Textbook Exercises R-5.3, R-5.4, R-5.9 (h) Textbook Exercise C-5.20 Hint: Leverage the fact that whether the last element is odd or even can be checked by the modulo operator (%) in Java and then based on this recur.

- 19- java. Which of the following is a drawback of using recursion? It may be less efficient than an iterative version. It may have fewer lines of code than an iterative version. It uses lesser memory stack than an iterative version. It runs faster than an iterative version.Answer the given question with a proper explanation and step-by-step solution. In Java, please. Consider the following problem. Input: an array of integers A[] Output: rearranges the array to have the following property: Suppose the first element in the original array A[], A[0] = x. In the rearranged array, suppose that x is at index i, that is A[i] = x. Then, we want the rearranged array to be such that A[j] <= x for all j < i and A[j] > x for all j > i. The rearranging should place all the values less than (or equal to) x to the "left" of x and all values larger than x to the right of x. Here's an example. Suppose the array has the elements in this initial order: 4 3 9 2 7 6 5 A[0] = 4. After rearranging elements, we get: 3 2 4 5 9 7 6 That is, A[0] = 4, is positioned in the resulting array so that all elements less than 4 (that is, 2, 3) are to its left (in no particular order), and all elements larger than 4 are to its right (again, in no particular order).Can i get help with this question, java language please 1 class QuicksortTester2 {34 /**5 * Quicksort algorithm (driver)6 */78 public void quicksort( int [ ] a )9 {10 quicksort( a, 0, a.length - 1 );11 }1213 /**14 * Internal quicksort method that makes recursive calls.15 * Uses median-of-three partitioning and a cut-off.16 */17public void quicksort( int [ ] a, int low, int high )19 {20 if( low + CUTOFF > high )21 insertionSort( a );22 else23 { // Sort low, middle, high24 int middle = ( low + high ) / 2;25 if( a[ middle ].compareTo( a[ low ] ) < 0 )26 swapReferences( a, low, middle );27 if( a[ high ].compareTo( a[ low ] ) < 0 )28 swapReferences( a, low, high );29 if( a[ high ].compareTo( a[ middle ] ) < 0 )30 swapReferences( a, middle, high );3132 // Place pivot at position high - 133 swapReferences( a, middle, high - 1 );34 int pivot = a[ high - 1 ];3536 // Begin partitioning37 int i, j;38 for( i = low, j = high - 1; ; )39 {40 while( a[ ++i ].compareTo( pivot ) < 0 )41…
