how to use getters and setters in java code example

Example 1: java get set

class Employ
{
  public String name;						//name of the employ
  
  public String getName()					//Get the name
  {
    return name;
  }
  
  public String setName(String newName)		//Set the name
  {
    this.name = newName;
  }
}

Example 2: java setter

public setValue(value) {
  this.value = value;
}

Example 3: js why to use getters and setters

1) Syntax reasons. It’s easier and faster to read code 
created with accessor functions
2) Encapsulation. I can create safer code with accessor functions.

Example 4: Getter and Setter methods

import java.util.Scanner;
class Student {
   private String name;
   private int age;
   Student(){
      this.name = "Rama";
      this.age = 29;
   }
   Student(String name, int age){
      this.name = name;
      this.age = age;
   }
   public void display() {
      System.out.println("name: "+this.name);
      System.out.println("age: "+this.age);
   }
}
public class AccessData{
   public static void main(String args[]) {
      //Reading values from user
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter the name of the student: ");
      String name = sc.nextLine();
      System.out.println("Enter the age of the student: ");
      int age = sc.nextInt();
      Student obj1 = new Student(name, age);
      obj1.display();
      Student obj2 = new Student();
      obj2.display();
   }
}
