Java-Exercises: Separate consonants and vowels from a given string.

Sample Solution-1:

Java Code:

public class test {
 
   public static void main(String[] args) {	   
	    String text = "Java";
		System.out.println("Original String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));
		text = "JavaScript";
		System.out.println("\nOriginal String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));
		text = "SQLite";
		System.out.println("\nOriginal String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));		
	}

   public static String validate(String text) {
		String text1 = text.replaceAll("(?i)[^aeiou]", "");
		String text2 = text.replaceAll("(?i)[aeiou]", "");
		return text2 + text1;
   }
}

Sample Output:

Original String: Java
Separate consonants and vowels of the said string: Jvaa

Original String: JavaScript
Separate consonants and vowels of the said string: JvScrptaai

Original String: SQLite
Separate consonants and vowels of the said string: SQLtie

public class test {
 
   public static void main(String[] args) {	   
	    String text = "Java";
		System.out.println("Original String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));
		text = "JavaScript";
		System.out.println("\nOriginal String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));
		text = "SQLite";
		System.out.println("\nOriginal String: "+text);
		System.out.println("Separate consonants and vowels of the said string: "+validate(text));		
	}

   public static String validate(String text) {
	    return text.replaceAll("[AEIOUaeiou]", "") +
		text.replaceAll("[^AEIOUaeiou]", "");
   }
}

Sample Output:

Original String: Java
Separate consonants and vowels of the said string: Jvaa

Original String: JavaScript
Separate consonants and vowels of the said string: JvScrptaai

Original String: SQLite
Separate consonants and vowels of the said string: SQLtie

Java: Tips of the Day

Split Java String by New Line

String lines[] = string.split("\\r?\\n");

There's only really two newlines (UNIX and Windows) that you need to worry about.
