Java programming Exercises: Replace all the vowels in a given string with a specified character
Java Regular Expression: Exercise-16 with Solution
Write a Java program to replace all the vowels in a given string with a specified character.
Sample Solution-1:
Java Code:
public class test {
public static void main(String[] args) {
String text = "LOWERED";
System.out.println("Original string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '#'));
text = "Java";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '*'));
text = "MID-CENTRALIZED";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '^'));
text = "C++";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '@'));
}
public static String validate(String text, char chr) {
return text.replaceAll("[aeiouAEIOU]", "" + chr);
}
}
Sample Output:
Original string: LOWERED After replacing vowel(s) with specified Character: L#W#R#D Original string: Java After replacing vowel(s) with specified Character: J*v* Original string: MID-CENTRALIZED After replacing vowel(s) with specified Character: M^D-C^NTR^L^Z^D Original string: C++ After replacing vowel(s) with specified Character: C++

Sample Solution-2:
Java Code:
public class test {
public static void main(String[] args) {
String text = "LOWERED";
System.out.println("Original string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '#'));
text = "Java";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '*'));
text = "MID-CENTRALIZED";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '^'));
text = "C++";
System.out.println("\nOriginal string: "+text);
System.out.println("After replacing vowel(s) with specified Character: "+validate(text, '@'));
}
public static String validate(String text, char chr) {
return text.replaceAll( "(?i)[aeiou]", String.valueOf(chr));
}
}
Sample Output:
Original string: LOWERED After replacing vowel(s) with specified Character: L#W#R#D Original string: Java After replacing vowel(s) with specified Character: J*v* Original string: MID-CENTRALIZED After replacing vowel(s) with specified Character: M^D-C^NTR^L^Z^D Original string: C++ After replacing vowel(s) with specified Character: C++

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
