Search Benchmarks

Modify the sequentialSearch and binarySearch methods presented in this chapter so they keep a count of and display on the screen the number of comparisons they make before finding the value they are searching for. Then write a program that has an array of at least 20 integers. It should call the sequentialSearch method to locate at least five of the values. Then it should call the binarySearch method to locate the same values. On average, which method makes the fewest comparisons?

. Now take any name from the user, find whether that name is present in that array or not, and print the position of that name in the array if found. Write a search method to sequentially search the name from the array. Invoke the search method from the main method. The array and the name to be searched should be passed into the search method as parameters.Now write a Java program to implement binary search for the above problem.[Hint: You can use equals() and compareTo() methods of String class.]
Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square. Program71.java Write a program that creates a 32-element array of random integers all from 1 to 100, inclusive. Then execute a custom method with the array as its only argument. The method should begin by using a loop to print the array elements in 4 rows and 8 columns, with all columns being five characters wide. Duplicates are okay. This same loop should determine how many integers in the array are odd numbers. After this loop ends, use this figure to declare a new array of integers named odds. Process the array again in the method, but this time with a foreach loop, and add the odd integers to the odds array. Return the odds array back to main. In main, report the size of the array and sort it ascending. Finally use a while loop to print the odd integers all on one line separated by spaces.
