OPA May8 Java

Create a class Player with below attributes:
playerId - int
skill - String
level - String 
points - int

 

Write getters, setters and parameterized constructor in the above mentioned attribute sequence as required. 

 

Create class Solution with the main method. 

Implement two static methods - findPointsForGivenSkill and getPlayerBasedOnLevel in Solution class.

 

findPointsForGivenSkill method:
This method will take two input parameters - array of Player objects and string parameter skill. 
The method will return the sum of the points attribute from player objects for the skill passed as parameter. 
If no player with the given skill is present in the array of player objects, then the method should return 0. 

 

getPlayerBasedOnLevel method:
This method will take two String parameters level and skill, along with the array of Player objects.
The method will return the player object, if the input String parameters matches with the level and skill attribute of the player object and its point attribute is greater than or equal to 20. If any of the conditions are not met, then the method should return null.

 

Note : No two player object would have the same value for skill and level attribute.
       All player object would have the points greater than 0.
       All the searches should be case insensitive.


These above mentioned static methods should be called from the main method. 

For findPointsForGivenSkill method - The main method should print the points as it is if the returned price is greater than 0, or it
should print "The given Skill is not available".

For getPlayerBasedOnLevel method - The main method should print the playerId of the returned player object. If the returned value is null
then it should print "No player is available with specified level, skill and eligibility points".

 

Before calling these static methods in main, use Scanner object to read the values of four Player objects referring attributes in the above mentioned attribute sequence. 
Next, read the value for skill and level.
Please consider the skill value read above as skill parameter for both the static methods.


Consider below sample input and output:

OPA JUNE 19 Java

Create a class AutonomousCar with the below attributes:


carld – int

brand – String noOfTestsConducted – int

noOfTestsPassed- int

environment – String

grade – String


Write getters, setters for the above attributes . Create constructor which takes parameter in the above sequence except grade.
Create class Solution with main method. Implement two static methods – findTestPassedByEnv and updateCarGrade in Solution class.


findTestPassedByEnv method:
This method will take two input parameters -array of AutonomousCar objects and string parameter environment. The method will return the sum of the noOfTestsPassed attribute from autonomousCar objects for the environment passed as parameter.


If no autonomousCar with the given environment is present in the array of AutonomousCar objects, then the method should return 0.
updateCarGrade method: This method will take a String parameter brand, along with the array of AutonomousCar objects. The method will return the autonomousCar object, if the input String parameter matches with the brand attribute of the autonomousCar object. Before returning the object, the grade should be derived based on the rating calculation mentioned below. This grade value should be assigned to the object. If any of the above conditions are not met, then the method should return null.


The grade attribute should be calculated as follows: rating .(noOfTestsPassed * 100)/noOfTestsConducted If the rating > = 80 then grade should be ‘A1’, otherwise the grade should be ‘B2’.
The above mentioned static methods should be called from the main method. For findTestPassedByEnv method – The main method should print the totalTestPassed as it is, if the returned value is greater than 0, or it should print “There are no tests passed in this particular environment”.


For updateCarGrade method – The main method should print the brand and grade of the returned autonomousCar object. The brand and grade should be concatinated with :: while printing. eg:- Tesla::A1, where Tesla is the brand and Al is the grade.
If the returned value is null then it should print “No Car is available with the specified brand”.


Before calling these static methods in main, use Scanner object to read the values of four autonomousCar objects referring attributes in the above mentioned attribute sequence (except grade attribute). Next, read the value for environment and brand.


input:
100
Tesla
1000
500
