Question

Exercise #3: write a Java program that prompts the user to enter a sentence. The program has to find the print: a. the position of vowels in the sentence. b. the number of vowels in the sentence (A, a, U, u, E, e, O, o, I, i) c. the number of characters as numbers or special characters (other than English letters a.z, A..Z). Hint: remember to ignore the spaces. Sample input-output: Enter the sentnse: UAEU is the university of the future #2018 The locations of vowels are: 0 2 3 5 10 12 14 16 19 23 28 31 33 35 The number of vowels is: 15 The number of characters as numbers or special characters is: 5

Answer 1

code:

==================================

import java.util.*;

public class Vowels
{
public static void main(String args[])
{
String str="";
int count=0,consonants=0,vowels=0;
int digits=0,spaces=0,special_charcters;
Scanner sc=new Scanner(System.in);
System.out.println("Enter a string:");
str=sc.nextLine();
  
System.out.print("The location of vowels are: ");
for(int i=0;i<str.length();++i)
{
switch(str.charAt(i))
{
case 'a':
case 'A':
case 'e':
case 'E':
case 'i':
case 'I':
case 'o':
case 'O':
case 'u':
case 'U':
count++;
System.out.print(i+" ");
}
}
//for counting no of digits and special characters
for(int i=0;i<str.length();++i)
{
char ch = str.charAt(i);
if(ch == 'a' || ch == 'e' || ch == 'i'
|| ch == 'o' || ch == 'u'||ch == 'A' || ch == 'E' || ch == 'I'
|| ch == 'O' || ch == 'U') {
++vowels;
}
else if((ch >= 'a'&& ch <= 'z')||(ch >= 'A'&& ch <= 'Z')) {
++consonants;
}
else if( ch >= '0' && ch <= '9')
{
++digits;
}
else if (ch ==' ')
{
++spaces;
}
  
}

special_charcters=(str.length())-consonants-spaces-vowels;
System.out.println("\nNumber of vowels is: "+count);
System.out.println("\nNumber of digits or special characters is: "+special_charcters);
}
}
