Chapter 10, Problem 10.9PE
(The Course class) Revise the Course class as follows:
- Revise the getStudents() method to return an array whose length is the same as the number of students in the course, (Hint: create a new array and copy students to it.)
- The array size is fixed in Listing 10.6. Revise the addStudent method to automatically increase the array size if there is no room to add more students. This is done by creating a new larger array and copying the contents of the current array to it.
- Implement the dropStudent method.
- Add a new method named clear() that removes all students from the course.

Shift Right k Cells (Use Python)
Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly.
Example:
source=[10,20,30,40,50,60]
shiftRight(source,3)
After calling shiftRight(source,3), printing the array should give the output as:
[ 0,0,0,10,20,30 ]
A bit new to methods and need a little bit of help.
Swap Method
Your task is to write a public static method named swap that takes a single parameter which is an array of doubles. This method should swap the first and last element in the array and then return the adjusted double array.
You can assume that all arrays passed into the method are a length of 2 or more.
For example, the test data provided when passed into the swap method should go from:
{8.34, 7.221, 10.643, 93.2}
to
Method Details:
public static void rotate(int[] array, boolean leftRotation, int positions)
Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help.
Parameters:
array -
leftRotation -
positions -
Throws:java.lang.IllegalArgumentException - When a null array parameter is provided

- Exercise (Array and Method): Write a method called arrayToString(), which takes an int array and return a String in the form of {a1, a2, ..., an}. Take note that there is no comma after the last element. The method's signature is as follows: public static String arrayToString(int[] array) Also write a test driver to test this method (you should test on empty array, one-element array, and n-element array).

- Create a class containing the main method. In the main method, create an integer array and initialize it with the numbers: 1,3,5,7,9,11,13,15,17,19 Pass the array as an argument to a method. Use a loop to add 1 to each element of the array and return the array to the main method. In the main method, use a loop to add the array elements and display the result. Note: In the loops, use the array field that holds the length of the array and do not use a number for array length.arrow_forwardJava: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting.

Complete the definition of the class DnaMax and method definition maxStrand shown below. If more than one strand has the same maximal number of the specified nucleotide you should return the longest strand with the maximal number. All DNA strands have different lengths in this problem so the maximal strand will be unique when length is accounted for. Return this uniquely maximal strand. Each String representing a DNA strand will contain only cytosine, guanine, thymine, and adenine, represented by the characters 'c', 'g', 't', and 'a', respectively. If no strand in the array contains the specified nucleotide return the empty string "". public class DnaMax { public String maxStrand(String[] strands, String nuc) { // fill in code here } } Constraints strands will contain no more than 50 elements,…arrow_forward
