Solving TCS IPA java question.(class Player)


Question:

 Create a Class Player with below attributes:


id - int

country - String

side - String

price - double


Write getters, setters and parameterized constructor as required. 


Create class Solution with main method. 


Implement static method - searchPlayerForMatch in Solution class.


This method will take a String parameter along with the other parameter as

array of Player objects. The method will return array of Player where the

String parameter appears in the side attribute (with case insensitive 

search).

  This method should be called from main method and display the id of

returned objects in ascending order. 


Before calling this method(searchPlayerForMatch) in the main method,

 use Scanner object to read values for four Player objects referring the 

attributes in the above sequence. 

then, read the value for search parameter. 

Next call the method searchPlayerForMatch, write the logic to sort the id

in ascending order (in main method) and display the result. 

---------------------------------------------------------------------

Consider below sample input and output:


Input:

1

India

Batting

2500000

2

Australia

Batting

1000000

3

Srilanka

Bowling

1700000

4

England

Bowling

2000000

Batting


Output:

1

2
