Program to remove vowels from a String

Given a string, remove the vowels from the string and print the string without vowels.

Examples:

Input : welcome to geeksforgeeks
Output : wlcm t gksfrgks

Input : what is your name ?
Output : wht s yr nm ?

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

A loop is designed that goes through a list composed of the characters of that string, removes the vowels and then joins them.

Java

// Java program to remove vowels from a String 
  
import java.util.Arrays; 
import java.util.List; 
  
class Test 
{     
    static String remVowel(String str) 
    { 
         Character vowels[] = {'a', 'e', 'i', 'o', 'u','A','E','I','O','U'}; 
           
         List<Character> al = Arrays.asList(vowels); 
           
         StringBuffer sb = new StringBuffer(str); 
           
         for (int i = 0; i < sb.length(); i++) { 
              
             if(al.contains(sb.charAt(i))){ 
                sb.replace(i, i+1, "") ; 
                i--; 
             } 
        } 
           
          
        return sb.toString(); 
    } 
    // Driver method to test the above function 
    public static void main(String[] args)  
    { 
        String str = "GeeeksforGeeks - A Computer Science Portal for Geeks"; 
          
        System.out.println(remVowel(str)); 
    } 
} 

Python

# Python program to remove vowels from a string 
# Function to remove vowels 
def rem_vowel(string): 
    vowels = ('a', 'e', 'i', 'o', 'u')  
    for x in string.lower(): 
        if x in vowels: 
            string = string.replace(x, "") 
              
    # Print string without vowels 
    print(string) 
  
# Driver program 
string = "GeeksforGeeks - A Computer Science Portal for Geeks"
rem_vowel(string) 

Output:

GksfrGks - A Cmptr Scnc Prtl fr Gks

We can improve the above solution by using Regular Expressions in Java.

// Java program to remove vowels from a String 
import java.util.Arrays; 
import java.util.List; 
  
class Test 
{     
    static String remVowel(String str) 
    { 
         return str.replaceAll("[aeiouAEIOU]", ""); 
    } 
      
    // Driver method to test the above function 
    public static void main(String[] args)  
    { 
        String str = "GeeeksforGeeks - A Computer Science Portal for Geeks";         
        System.out.println(remVowel(str)); 
    } 
}
