Usage

From source file:Main.java

public static void main(String[] args) {
    System.out.println("Enter a string");
    Scanner input = new Scanner(System.in);
    String s1 = input.nextLine();
    s1 = s1.trim();
    int howLong = s1.length();

    for (int counter = 0; counter < howLong; counter++) {
        char ch = s1.charAt(counter);
        System.out.print(ch);//from  w w  w .  j  ava 2 s.  c o m
    }

}

From source file:example.ToCommonsNotBlank.java

public static void main(String[] args) {
