- problem statement: Write a java classStringCheckto do the below given checks on accepted string or strings. Each function should be coded in separate methods of the class. Give appropriate instance variables to implement the method. The user should be able to enter the string through the main function in Main class. Use a constructor to initialize the String entered by the user. Use the Main class to test all the methods in StringCheckclass. The programs should have the below given checklist: 1)Define classStringCheck with required instance variables 2)The StringCheck class should have six methods to do the below functions: *Check if the user entered string is a simple sentence? (Starts with capital letter, Ends with period, space between words). *Check if the user entered string is a question? (Check if the string starts with ac apital letter ends with a question mark, space between words) *Check if the user entered string have numbers in it? *Check if string is a valid email *Check…java programming Robot Class : a robot has a name , located at a point with integer coordinates , faces north , east , south , or west and keeps a record of all its movements positions . The class has the following methods : A default constructor that initializes robot's name to " Unknown ” , location to ( 0,0 ) , direction to North , and travelled distance to 0 , and simulated movements to null . A constructor that given robot's name , starting location , and facing direction , Accessor methods to access all the instance variables and the simulated movements of the robot Mutator methods that change the instance variables to given values and they made the change for only suitable values . tumLeft and turn Right methods that change the direction of the robot but not the location move method that moves the robot by one unit in the direction it is facing . get Travelled Distance method that retums how many units has the robot moved .30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank you
- Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than $150• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all…1.
