Answer 1

Television.java:

public class Television {

   private String brand;
   private double price;
   public Television() {

   }
  
   public Television(String brand, double price) {
this.brand = brand;
       this.price = price;
   }

   public String getBrand() {
       return brand;
   }
   public double getPrice() {
       return price;
   }
   public void setBrand(String brand) {
       this.brand = brand;
   }
   public void setPrice(double price) {
       this.price = price;
   }

   public String toString() {
       return "Brand Name: "+getBrand()+" Price: "+getPrice();
   }
  
   public boolean equals(Television television2) {
          
       if(getBrand().equals(television2.getBrand()) &&
               getPrice()==television2.getPrice()) {
           return true;
       } else{
           return false;
       }
   }  
}

TelevisionTest.java:

import java.util.Scanner;

public class TelevisionTest {

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);
       String brand;
       double price;
       System.out.println("Enter Television1 Name:");
       brand = sc.next();
       System.out.println("Enter Television1 Price:");
       price = sc.nextDouble();
       Television television1 = new Television(brand, price);
       System.out.println("Enter Television2 Name:");
       brand = sc.next();
      
       System.out.println("Enter Television2 Price:");
       price = sc.nextDouble();

      System.out.println("--------------------------");
       System.out.println("Television1 Details are:");
       System.out.println("getBrand(): "+television1.getBrand());
       System.out.println("getPrice(): "+television1.getPrice());

       System.out.println("toString() method result: "+television1);
       System.out.println("--------------------------");
       System.out.println("Television2 Details are:");
       System.out.println("getBrand(): "+television2.getBrand());
       System.out.println("getPrice(): "+television2.getPrice());

       System.out.println("toString() method result: "+television2);

       System.out.println("--------------------------");
       System.out.println("Checking equals method");
       if(television1.equals(television2)) {
           System.out.println("Both televisions are equals");
       } else {
           System.out.println("Both televisions are not equals");
       }

   }

}
