}

From source file:Main.java

public static void main(String[] args) {
    StringBuffer sb = new StringBuffer("this is a test");

    System.out.println(sb);//from  w w w .j av a  2s  .  c o m
    String strPart1 = sb.substring(5);

    System.out.println(strPart1);
    String strPart2 = sb.substring(0, 17);

    System.out.println(strPart2);
}

From source file:MainClass.java

    StringBuffer newString = new StringBuffer("abcde");

    System.out.println(newString.capacity());

    newString.ensureCapacity(40);/*ww w. j a  v  a2s  . c  o m*/

    System.out.println(newString.capacity());
}

From source file:MainClass.java

    StringBuffer sb2 = new StringBuffer("xy");
    System.out.println(sb2);

    sb2.insert(1, true);
    System.out.println(sb2);
}
