PA Programming Solution Java - 10 February 2020

Q1. 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);
    }
}

Q2.  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:

100
Sachin
5
150
13000
101
Sehwag
4
120
10000
103
Dhoni
7
110
7000
104
Kohli
15
57
4400


100


Output:

Grade A
Grade A
Grade B
