}

From source file:Main.java

public static void main(String[] arg) {
    StringBuffer buf = new StringBuffer("1234567890");
    String aString = "abcdefghijk";

    System.out.println(buf);
}

From source file:Main.java

    sb.setCharAt(1, 'i');
    System.out.println("buffer after = " + sb);
    System.out.println("charAt(1) after = " + sb.charAt(1));

}
