Java program to remove vowels from string using StringBuffer class

In this article we are going to learn java program to remove vowels from string using StringBuffer class.

Java program to remove vowels from string using StringBuffer class

Here’s how to write a java program for remove vowels from string using StringBuffer class,

Also read – remove vowels from string using switch case

import java.util.Arrays;
import java.util.List;

public class RemoveVowelsInString 
{
   static String removeVowel(String strVowel) 
   { 
      Character vowel[] = {'a', 'e', 'i', 'o', 'u','A','E','I','O','U'};   
      List<Character> li = Arrays.asList(vowel);   
      StringBuffer strBuffer = new StringBuffer(strVowel);   
      for(int a = 0; a < strBuffer.length(); a++) 
      {      
         if(li.contains(strBuffer.charAt(a)))
         { 
            strBuffer.replace(a, a + 1, "") ; 
            a--; 
         }
      }
      return strBuffer.toString(); 
   }

   public static void main(String[] args)
   {
      String strInput = "Hello World Java";
      System.out.println(removeVowel(strInput)); }
   }
}

Output:

Hll Wrld Jv

Similarly we can write java program to remove vowels from a string using method,

public class VowelRemove 
{
   static String removeVowel(String strVowel) 
   { 
      return strVowel.replaceAll("[aeiouAEIOU]", ""); 
   }

   public static void main(String[] args) 
   {
      String strInput = "Flower Brackets";         
      System.out.println(removeVowel(strInput));
   }
}

Output:
