    System.out.printf("buffer = %s\n", buffer.toString());
    System.out.printf("Character at 0: %s\nCharacter at 4: %s\n\n", buffer.charAt(0), buffer.charAt(4));

    char charArray[] = new char[buffer.length()];
    buffer.getChars(0, buffer.length(), charArray, 0);
    System.out.print("The characters are: ");

}

From source file:MainClass.java

public static void main(String[] arg) {

public static void main(String[] arg) {
    StringBuffer phrase = new StringBuffer("one two three four");
    String substring = "two";
    String replacement = "twenty";
    int position = phrase.lastIndexOf(substring); // Find start of "two"
    phrase.replace(position, position + substring.length(), replacement);

    System.out.println(phrase);//from  w ww  . jav  a  2 s . co m
}
