Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt().
Also analyze the program's performance and state the big-O complexity of your method.
Provide a screenshot of the code working.
Redefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method. (Remember, you should use getClass(), not instanceof.)

- You are to implement removeHead, and removeTail and you also have to create the following functions (for visual purposes of the detail explanation, header and trailer sentinels are described as h and t respectively): IMPORTANT NOTE: For all the methods that has the pos parameter i.e. addAt, removeAt, move, make sure to access that specified position from whichever is nearer - the head or the tail - similar to what we have done in the get method. Example DoublyLinkedList: h <-> 10 <-> 30 <-> 40 <-> 50 <-> t int add(int num) This will add the element num into the last element of the linked list and return the position of the newly-added element. In the above example, having add(60) will return 5 as it is the fifth position in the list. int remove(int num) This will remove the first instance of the element and return the position of the removed element. In the above example, having remove(40) will return 3 as 40 was the third element in the linked list…arrow_forwardCreate the compareTo method for a class that represents an individual whose first and last names are stored as two Strings. In an alphabetical list of people with last names first and then first names, one individual is "less than" another if they come before the other.(as is typical).arrow_forwardCopy your previous class definition for RectangularSolid from the previous problem, including both methods. Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators). These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.arrow_forward
- The following code is poorly structured. Rewrite it so that it has a better structure and avoids redundancy. To help eliminate redundancy, convert the code into a method named spending that accepts two parameters: a Scanner for the console, and a String for a single person's name, and prints the appropriate information about that person's bills. Your method could be called twice (once for John and once for Jane) to replicate the original code's behavior.arrow_forwardShow me the ropes for creating a method that accepts both primitive and reference kinds of parameters.arrow_forwardTrace (in details) the calling of this method.arrow_forward
- Can someone help in java Create a class Hotel with member data, hotel name and category (number of stars).For the Hotel class, write the standard methods (constructors, get & set, toString ()) and the getWiFi () method, which returns the wifi address formed by the first 4 letters of the hotel name and any number (you can get it with the random number generator) .In main (), illustrate the use of the Hotel class. Create a PopulatedHotel class, successor to the Hotel with an additional ArrayList <> field on behalf of the hotel guests.For the PopulatedHotel class, write standard methods (constructors, get & set, toString ()), with the get and set methods working with separate elements of ArrayList <>. For the PopulatedHotel class, also write methods for adding and removing a guest and a method for checking that a person is staying at the hotel. In main (), illustrate the use of the PopulatedHotel class.arrow_forwardAdd a toString() method to Fraction class that returns the fraction as aString in the form "x / y", where x and y are numerator and denominatorrespectively. As the method does not do any display itself, the output can be done by a client program that calls the method in an output statement. Use client program to test this functionality; i.e. provide an output statement to display a fraction as its String representation. class Fraction2{private int n, d;public Fraction(){this.n = this.d = 0; //Initialize the values}public Fraction(int n, int d){this.n = n; //Initialize the variablesthis.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;} //Define the getter function getDen() that returns the denominatorpublic int getDen(){//Returns denominatorreturn d;}//Define the boolean function isZero() that returns 0 if numerator is 0 and denominator is not equals to zeropublic boolean isZero(){return(getNum() == 0 &&…arrow_forwardGive a brief explanation of a method before going through its three main parts.arrow_forward
