Java Proctored Assessment Programming solution 10th February​


Question 1.

Write a Java program to read a string str and to count both vowels and consonants in that string.




Input:

Hello World!




Output:

Vowels count - 3

Consonants count - 7

​

Solution:

​

import java.util.*;

import java.lang.*;

public class Main

{

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

String str = s.nextLine();

str = str.toLowerCase();

int vowelCount = 0, consonantCount = 0;

for(int i=0;i<str.length();i++){

if(str.charAt(i)>='a' && str.charAt(i)<='z'){

if(str.charAt(i)=='a' || str.charAt(i)=='e' || str.charAt(i)=='i' || str.charAt(i)=='o' || str.charAt(i)=='u')

vowelCount += 1;

else

consonantCount += 1;

}

}

System.out.println("Vowels count - "+vowelCount);

System.out.println("Consonant Count - "+consonantCount);

}

}

​

Question 2.

​

Write a class named as Main. Read the following parameters

- id (int)

- name (String)

- exp (int)

- matchesPlayed (int)

- runsScored (int)

​

Calculate the average of the players in that innings depends upon the target(int)

- if avgRuns >=80 and <=100, print Grade A

- if avgRuns >=50 and <=79, print Grade B

- else, print Grade C

​

Input:
