Write a java program to input a sentence and count how many words are starting with vowel alphabet.
Sir which compiler u r use….?
public class VowelInString {
public static void main(String[] args) {
String s="Hello";
int count=0;
for(char c: s.toCharArray()) {
if(c=='a' || c=='e' || c=='i' ||c=='o' ||c=='u') {
count++;
}
}
System.out.println(count);
}
}
Great video 👍! Please Like, Share and Subscribe to my channel for unique Java challenges. You’ll ❤️ them, I promise!
explain flow !!!
I think here pattern and matcher will work very efficiently
code:
import java.util.*;
import java.util.regex.*;
public class VowelCounter{
public static void main(String [] args){
Scanner sc=new Scanner(System.in);
sysout("Enter String:");
String str=sc.nextLine();
Pattern p; p=Pattern.compile("[aeiouAEIOU]");
Matcher m=p.matcher(str);
int count=0;
while(m.find()){
count++;
}
sysout("No. of Vowels:"+count);
}
}
Sir, as you know most of the students who all are watching this video are beginners and you have used that for loop in such a way that most of the people will get confused by watching the use of for loop. So, sir please explain it in a way that everyone will understand. And yes, sir I like all of your videos it helps me a lot.
write a java program to get a string and collection of number from the user and print characters from a string based on the collection number as index in java
We can use HashSet to count the vowels. In the HashSet we will pass the vowels as an Arrays.asList('e', 'i' ,'u','o','a').
The complete code is below:
class Abc1
{
public static void main(String[] args) {
String a = "Protijayi";
CountVowels(a);
}
private static void CountVowels(String aa) {
String a = aa.toLowerCase();
int c = 0;
int c1 =0;
HashSet<Character> set = new HashSet<>(Arrays.asList('e', 'i' ,'u','o','a'));
for (int i = 0; i < a.length(); i++) {
char ch = a.charAt(i);
if(set.contains(ch)) {c++ ;}
else {c1++ ;}
}//for
System.out.println("Vowels => " + c);System.out.println("consonents => " + c1);
}
}
Long process
U could have used THIS — Suppose
String a={A,E,I,O,U}
And then use .compareTo ().
How can I separate the Word for example
Cats, I want to print
cat/noun +s/plural
