java program to remove vowels from a string code example
Example 1: Java program to remove vowels from string using StringBuffer class
import java.util.Arrays;
import java.util.List;
public class RemoveVowels
{
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));
}
}
Example 2: Java program to delete vowels in a given string
import java.util.*;
public class RemoveVowelsInString
{
public static void main(String[] args)
{
String str = "Deekshit Prasad";
System.out.println("Given string: " + str);
str = str.replaceAll("[AaEeIiOoUu]", "");
System.out.println("After deleting vowels in given a string: " + str);
}
}
Example 3: Remove vowels from a string in java using for loop
import java.util.ArrayList;
import java.util.List;
public class RemoveVowelsUsingForLoop
{
public static void main(String[] args)
{
String str = "Hello world core java";
String strResult = removeVowels(str);
System.out.println("Remove vowels using for loop: " + strResult);
}
private static String removeVowels(String str)
{
List<Character> al = new ArrayList<Character>();
al.add('a');
al.add('e');
al.add('i');
al.add('o');
al.add('u');
al.add('A');
al.add('E');
al.add('I');
al.add('O');
al.add('U');
StringBuffer sb = new StringBuffer(str.toLowerCase());
for(int a = 0; a < sb.length(); a++)
{
if(al.contains(sb.charAt(a)))
{
sb.replace(a, a + 1, "");
a--;
}
}
return sb.toString();
}
}
