Answer 1

Answer:

The program to this question can be given as follows:

Program:

class player//defining class player

{

//defining variable name and score.

String name;

int score;

String get_Name() //defining method get_Name

{

return name; //return value.

}

void set_Name(String name) //defining method set_Name

{

//using this keyword to hold variable value

this.name = name; //hold value

}

int get_Score() //defining method get_Score

{

return score; //return value

}

void set_Score(int score) //defining method set_Score

{

//using this keyword to hold variable value

this.score = score; //return value

}

}

public class Main //defining class Main

{

public static void main (String[] args) //defining main method

{

//defining variable

int x;

String n;

player ob= new player(); //creating player class Object

ob.set_Name("data"); //calling function set_Name and pass the value.

ob.set_Score(10); //calling function set_Score and pass the value.

n=ob.get_Name(); //holding value

x=ob.get_Score();//holding value

System.out.println(n+"\n"+x); //print value.

}

}

Output:

data

10

Explanation:

In the above java program, the class player is defined, which contains two-variable "name and score" in which the name is a string type and score is an integer type.

• In the next line, the getter and setter method is used, which is set is used to set the values and get is used to return the values.
• Then the Main class is declared inside the class the main method is defined that creates a player class object and call the function.
