In the given question if the class student has member variable gpa also we have a method having the argument gpa with the help of this keyword we can refer the gpa variable inside the method .
Following are the implementation of the given question
public class Main // main class
{
int gpa; // variable declaration
public Main(int gpa) // constructor
{
this.gpa = gpa; // this keyword
}
public static void main(String[] args) // Main method
{
Main m= new Main(55); // creating object of class
System.out.println("The Value of gpa is : " + m.gpa); // display value
}
}
Output:
The Value of gpa is :55

Using version control tools like Git and Github.
Explanation:
Version control is a vital tool in programming in recent times. it helps to prevent loss of source codebase and creating unwanted folders for storing multiple codebases to prevent excess storage usage and time consumption.
Git and Github is a platform that handles version control and collaboration between co-workers. When a repository is created, its initial branch is called the master branch and when a staged code is committed, the commit is recorded. These records can be retrieved using the commit hash value and resetting the current unstaged file or code. A new branch can created to hold a different version of an application and merged later with the master branch.
