Removing vowels from String in Java

Following are the steps to remove vowels from a string:

• Input a string from the user.
• Pass the string to removeEvenElements() method.
• Inside a method, first, create an empty string buffer.
• Now, iterate over the string and check the index value. Now check, if we found vowels at an even position then remove it.
• At last, just return the string in a string buffer.

import java.util.Scanner;

public class Main {
                public static void main(String[] args) {
                			Scanner sc = new Scanner(System.in);
                			String s1 = sc.nextLine();
                                
                                System.out.println(removeEvenElements(s1));
                }
                public static String removeEvenElements(String s1) {
                                StringBuffer sb1=new StringBuffer();
                                for(int i=0;i<s1.length();i++)
                                                if((i%2)==0)
                                                                sb1.append(s1.charAt(i));
                                                else if((i%2)!=0)
                                                                if(s1.charAt(i)!='a' && s1.charAt(i)!='e' && s1.charAt(i)!='i' && s1.charAt(i)!='o' && s1.charAt(i)!='u')
                                                                                if(s1.charAt(i)!='A' && s1.charAt(i)!='E' && s1.charAt(i)!='I' && s1.charAt(i)!='O' && s1.charAt(i)!='U')
                                                                                 sb1.append(s1.charAt(i));
                                return sb1.toString();
                }
}

Java Program to Remove vowels from the string

Following are the steps to remove vowels from the string in Java:

• Input a string from the user.
• Add vowels to the list using Arrays.asList();
• Convert string to character array using toCharArray() method.
• Create an empty string buffer.
• Now, traverse over each character and check if the list of vowels does not contain any specified character. If it is true then append that character to the string buffer.
• At last, print the element in a string buffer.

package com.company;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Scanner;

public class RemoveVowel {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
         String str = scanner.nextLine();
         List<Character> list = Arrays.asList('a','e','i','o','u','A','E','I','O','U');
         char c[] = str.toCharArray();
         StringBuffer sb = new StringBuffer();
         for(Character newchar : c ){
             if(!list.contains(newchar)){
                 sb.append(newchar);
             }
         }
        System.out.println(sb);
    }
}

Output

Thus, in this way, we learned how to remove vowels from even positions along with removing vowels from the whole string.
