Java Array Hands on Problem 2 TCS Programming

Create class Book with below attributes:

id – int

title – String

author – String

price – double

Write getters, setters and parameterized constructor as required. 

Create class Solution with main method. 

Implement static method – searchTitle in Solution class.

This method will take a parameter of String value along with other parameter as array of Book objects. 

It will return array of books where String value parameter appears in the title attribute (with case insensitive search).

This method should be called from main method and display id of returned objects in ascending order. 

Before calling this method, use Scanner object to read values for four Book objects referring attributes in the above sequence. 

Next, read the value search parameter. 

Next call the method and display the result. 

Consider below sample input and output:

Input:

1

hello world

aaa writer

50

2

World cup

bbb writer

55

3

Planet earth

ccc writer

45

4

India’s history

ddd writer

40

WORLD

Output:

1

Java Arrays - Hands on 2
Problem 2:
 
Create class Book with below attributes:
 
id - int
title - String
author - String
price - double
 
Write getters, setters and parameterized constructor as required. 
 
Create class Solution with main method. 
 
 
 
Implement static method - searchTitle in Solution class.
 
 
 
This method will take a parameter of String value along with other parameter as array of Book objects. 
It will return array of books where String value parameter appears in the title attribute (with case insensitive search).
 
This method should be called from main method and display id of returned objects in ascending order. 
 
Before calling this method, use Scanner object to read values for four Book objects referring attributes in the above sequence. 
Next, read the value search parameter. 
 
Next call the method and display the result. 
 
Consider below sample input and output:
 
Input:
1
hello world
aaa writer
50
2
World cup
bbb writer
55
3
Planet earth
ccc writer
45
4
India's history
ddd writer
40
WORLD
 
Output:
