JAVA: Suppose that we have a sorted int array called x, with n elements in it and some room to add more elements. Write the code segment that would add a new item, called target, to the array, so that the array will still be sorted once you are done.
1. Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen2. In the same program, insert an element in the above ArrayList at index 2. The resulting Array Listmust be one element larger. Print the resulting list to the screen.3. In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.4. In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.5. In the same program, use a 'for' loop to print each element of the Array List to the screen.6. Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.

Student: Michael Reyes 2. Write a Java program that would resemble a payroll system. An input window that will accept the employee number and the number of days of rendered work. A 2d-ArrayList that contains the employee number and the rate per day is to be searched and used to compute the gross salary. Gross salary is computed by multiplying the number of days of rendered work by the rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and net pay in an output window. Design your own input/output windows. (USE OOP CONCEPT JFRAME)
