Usage

From source file:Main.java

public static void main(String[] argv) {
    StringBuilder sb = new StringBuilder(20);
    System.out.println(sb.capacity());
}

From source file:Main.java

public static void main(String args[]) {
    StringBuilder sb = new StringBuilder("This is a test from java2s.com.");

    sb.replace(5, 7, "was");
    System.out.println("After replace: " + sb);
}

From source file:Main.java

public static void main(String args[]) {
    StringBuilder sb = new StringBuilder("java2s.com.");

    sb.deleteCharAt(0);//from w  w  w . j a va 2 s.c  om
    System.out.println("After deleteCharAt: " + sb);
}

From source file:Main.java

public static void main(String[] args) {
    StringBuilder sb = new StringBuilder(200); // Capacity:200, length:0
    sb.append("Hello"); // Capacity:200, length:5
    int len = sb.length(); // len is assigned 5
    int capacity = sb.capacity(); // capacity is assigned 200

}

From source file:Main.java

public static void main(String args[]) {
    StringBuilder sb = new StringBuilder("java2s.com");
    System.out.println("buffer before = " + sb);

    sb.setLength(2);/*from w w w.  ja  v a  2  s  .c  o m*/
    System.out.println("buffer after = " + sb);
}

From source file:Main.java

public static void main(String args[]) {
    StringBuilder buffer = new StringBuilder("hello java2s.com");

    System.out.println(buffer.charAt(0));
    System.out.println(buffer.charAt(4));

}

From source file:Main.java

public static void main(String[] arg) {
    StringBuilder phrase = new StringBuilder("java2s.com");
    int position = phrase.lastIndexOf(".com");

    System.out.println(position);
}
