javascript setter and getter code example

Example 1: javascript class getter setter

// *** JS Class GETTER / SETTER (+split)

	class Person {
        constructor(firstname, lastname) {
            this.firstname = firstname;
            this.lastname = lastname;
        }
        // getters => access properties
        // setters => change or mutate them
        get fullName() {
            return `Hello ${this.firstname} ${this.lastname}`;
        }
        set fullName(space) {
            const parts = space.split(' ');
            this.firstname = parts[0];
            this.lastname = parts[1];
        }
    }
    let run = document.getElementById("run");
    run.addEventListener('click', () => {
        let john = new Person('John', 'Connor');
        console.log(john.fullName);
        john.fullName = 'Billy Butcher';
        console.log(john.firstname + ' ' + john.lastname);
      	//console.log(`${john.firstname} ${john.lastname}`); same output
      // => has to be john.firstname otherwise undefined 
    }) 
// output => Hello John Connor | Billy Butcher

Example 2: getters and setters javascript

let obj = {
  log: ['a', 'b', 'c'],
  get latest() {
    if (this.log.length === 0) {
      return undefined;
    }
    return this.log[this.log.length - 1];
  }
};

obj.log.push('d');
console.log(obj.latest); //output: 'd'

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();
   }
}
