TermCommentPost For Java StringBuffer Examples

temp starts as “abcdefghgfedcba”

method is:

public static void StrPractice(String temp) {
String str = temp;
StringBuffer sb = new StringBuffer(str);
sb.append(“_tree”);
sb.append(3.14159);
// prints “abcdefghgfedcba_tree3.14159”
System.out.println(sb);
// displays capacity as 31 (original string buffer value before appending 2x)
System.out.println(“String Buffer Capacity: ” + sb.capacity());

// just create the string and string buffer without appending
String st = “abcdefghgfedcba_tree3.14159”;
StringBuffer sbq = new StringBuffer(st);
System.out.println(sbq.capacity() + ” ” + sbq.length());
// displays capacity as 43 and length as 27
}

why does it only display the capacity what was originally placed in the string buffer and not the new string buffer if I append characters to it?

well explaination…………but should have given atleast 1 complete example.
