JAVA Write a program which will read a text file into an ArrayList of Strings. Note that the given data file (i.e., “sortedStrings.txt”) contains the words already sorted for your convenience. • Read a search key word (i.e., string) from the keyboard and use sequential and binary searches to check to see if the string is present as the instance of ArraryList. • Refer to “SearchInt.java” (given in “SearchString.zip”) and the following UML diagram for the details of required program...
Write Java program to compare time consumed by linear search and binary search to search for non-exit element in arrays of length 1000, 100000,500000,1000000. Hints: - Use Random class, method nextInt(a.length) to generate random numbers. - Select an element that is greater than a.length. - Use Arrays.sort(a) to sort the array before using binarySearch.

*Java* Hi. I need some help with creating generic methods in Java. Write a program GenMethods that has the following generic methods: (1) Write the following method that returns a new ArrayList. The new list contains the nonduplicate (i.e., distinct) elements from the original list. public static ArrayList removeDuplicates(ArrayList list) (2) Write the following method that shuffles an ArrayList. It should do this specifically by swapping two indexes determined by the use of the random class (use Random rand =...

Need assistance with this problem. This is for a java class and using eclipse. For this assignment we’ll be doing problems 21.3 and 21.4 from your textbook. Problem 21.3 asks you to write a generic method that removes duplicate items from an ArrayList. This should be fairly straightforward. Problem 21.4 asks you to implement insertion sort within a generic method. Insertion sort is described in detail on pages 250-252 of your textbook. You can write your two methods in a...
