Consider the following implementation of binarySearch: public static bool binarySearch(int[] a, int item) { int first = 0; int last = a.length - 1; while( first <= last) { int mid = (first + last)/2; if(a[mid] == item) return true; else if (a[mid] < item) first = mid + 1; last = mid - 1; else } return false; } how many times is the line of code int mid = (first + last)/2; executed when it is called with a = {2, 3, 5, 7, 11, 13,17, 19, 23, 29, 31, 37} and item = 2?

Write all the code within the main method in the Test Truck class below. Implement the following functionality.  a) Constructs two truck objects: one with any make and model you                  choose and the second object with gas tank capacity 10.  b) If an exception occurs, print the stack trace.  c) Prints both truck objects that were constructed.   import java.lang.IllegalArgumentException ;  public class TestTruck {            public static void main ( String [] args )              {   heres the truck class information  A Truck can be described as having a make (string), model (string), gas tank capacity (double), and whether it has a manual transmission (or not). Include the following methods in your class definition. . An overloaded constructor which takes the make and model. This method throws an IllegalArgumentException if the make is "Jeep". An overloaded constructor which takes the gas tank capacity. This method throws an IllegalArgumentException if the capacity of the gas…

JAVA Language:  Transpose Rotate.  Question:  Modify Transpose.encode() so that it uses a rotation instead of a reversal. That is, a word like “hello” should be encoded as “ohell” with a rotation of one character.
