The educational content outlines the following problem statement and tasks related to Java programming:### Problem Statement:Develop a Java class, `StringCheck`, to perform a series of checks on accepted strings. Each function should be implemented as separate methods within the class. Users will input strings via the main function in a `Main` class, which initializes these strings through a constructor. The `Main` class will also test all methods in the `StringCheck` class.### Program Requirements:1. **Define Class:** - Create the `StringCheck` class with necessary instance variables.2. **Methods in StringCheck Class:** - Implement six methods for the following checks: - **Simple Sentence:** Verify if the string starts with a capital letter, ends with a period, and contains spaces between words. - **Question:** Check if the string starts with a capital letter, ends with a question mark, and contains spaces between words. - **Contains Numbers:** Determine if the string includes numbers. - **Email Validation:** Check if the string is a valid email address. - **String Equality:** Compare two different strings to see if they are identical. - **Character Presence:** Confirm if a specific character is present in the string. Include a second constructor to initialize both string and character when an object is created.3. **Documentation:** - Comment all parameters using `@param` and return values using `@return` before each method to explain the inputs and outputs.4. **Main Class Development:** - Write a `Main` class that accepts one or more strings from the user and tests them using the `StringCheck` class methods.5. **Testing:** - Provide each test string used, along with the test results and output of the program.This content should help students understand Java class design, method implementation, and effective commenting practices in programming.

In cases with multiple questions, we are needed to solve first three.

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 a c 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 if the user entered strings (two separate strings) are same? A method to check if the user entered character is present in the user entered string. Add a second constructor to initialize string and character when object is created.

Programing language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: “Jim Lahey - Age 57- Phone 9025555555”.
In GO language. Create a struct that has student name, id, and GPA. Write functions to create a student, modify the student’s id, and modify the student's GPA, and print the student’s information. (This is like creating a class and methods). Now create an array of three students and test your functions. You may hardcode your values if using a web conpiler. (Please hardcode the values!)
