Usage

From source file:Main.java

public static void main(String[] arg) {

    StringBuilder buffer = new StringBuilder("from java2s.com");

    buffer.append(buffer);/*w w  w .j a  v a  2s  .co  m*/

    System.out.println(buffer);
}

From source file:Main.java

public static void main(String[] args) {
    StringBuilder lipsum = new StringBuilder("Lorem ipsum dolor sit amet.");
    System.out.println("lipsum = " + lipsum.toString());

    lipsum.delete(0, 28);//from   www .  j  a v a  2s  .com
    System.out.println("lipsum = " + lipsum.toString());

    lipsum.deleteCharAt(lipsum.length() - 1);
    System.out.println("lipsum = " + lipsum.toString());
}

From source file:Main.java

public static void main(String[] a) {
    StringBuilder builder = new StringBuilder("Line 1\n");

    builder.append("Line 3\n");

    String lineToInsert = "Line 2\n";

    builder.insert(0, lineToInsert);/*ww  w . j  a va2s . c  o  m*/

    System.out.println(builder.toString());

}

From source file:Main.java

public static void main(String[] a) {
    StringBuilder builder = new StringBuilder("Line 1\n");

    builder.append("Line 3\n");

    builder.insert(0, "Line 2\n");

    System.out.println(builder.toString());

    builder = builder.delete(2, 6);// w  w  w  .j ava 2s . c  om

    System.out.println(builder.toString());

}

From source file:Main.java

public static void main(String[] args) {
    // Length is 5
    StringBuilder sb = new StringBuilder("Hello");

    // Now the length is 7 with last two characters as null character '\u0000'
    sb.setLength(7);/*  www  .  jav a2s  .com*/

    // Now the length is 2 and the content is "He"
    sb.setLength(2);

}

From source file:Main.java

public static void main(String[] arg) {

    String phrase = "abced";
    StringBuilder buffer = new StringBuilder(phrase);

    System.out.println(buffer);//from  w ww. j a  va  2s  .c  o m
}

From source file:Main.java

public static void main(String[] arg) {

    CharSequence phrase = "abced";
    StringBuilder buffer = new StringBuilder(phrase);

    System.out.println(buffer);/*from  w  ww.ja  v a 2s  . co m*/
}

From source file:Main.java

public static void main(String[] args) {
    // Create a String object
    String s1 = new String("Hello");

    // Create a StringBuilder from of the String object s1
    StringBuilder sb = new StringBuilder(s1);

    // Append " Java" to the StringBuilder's content
    sb.append(" Java"); // Now, sb contains "Hello Java"

    // Get a String from the StringBuilder
    String s2 = sb.toString(); // s2 contains "Hello Java"

}

From source file:Main.java

public static void main(String args[]) {

    // create an empty array list
    ArrayList<StringBuilder> arrlist1 = new ArrayList<StringBuilder>();

    // use add for new value
    arrlist1.add(new StringBuilder("from java2s.com"));

    // using clone to affect the objects pointed to by the references.
    ArrayList arrlist2 = (ArrayList) arrlist1.clone();

    // appending the string
    StringBuilder strbuilder = arrlist1.get(0);
    strbuilder.append("tutorials");

    System.out.println(arrlist1);

    System.out.println(arrlist2);
}

From source file:NavigableSetDemo.java

public static void main(String[] args) {
    List<Integer> list = Arrays.asList(3, 2, 4, 1, 5);
    NavigableSet<Integer> ns = new TreeSet<Integer>(list);
    System.out.println("Ascending order (default): " + ns);

    Iterator<Integer> descendingIterator = ns.descendingIterator();
    StringBuilder sb = new StringBuilder("Descending order: ");
    while (descendingIterator.hasNext()) {
        int m = descendingIterator.next();
        sb.append(m + " ");
    }// w  ww  .  j  a v a 2 s . c  o  m
    System.out.println(sb);

    int greatest = ns.lower(3);
    System.out.println("Lower of 3 = " + greatest);

    int smallest = ns.higher(3);
    System.out.println("Higher of 3 = " + smallest);
