Java

right /prog/ i've never used a text board on here, so, here goes. I would like a small hand with some basic java programming. I am using the BlueJ environment.

Given two Strings s1 and s2 already defined as

String s1 = "SESQUIPEDALIANISM";
String s2 = "";

write a sequence of lines of java code that will make String s2 contain (only)
the letters number 3, 10 and 12 from s1
(e.g. if s1 was "piano"
s2 containing letters 1, 3 and 4 would make s2 = "pan").

/* StringBuffer provides synchronization so this code can be executed

StringBuffer stringBuffer = new StringBuffer();

/* Construct the result string by concatenating substrings
   of s1. */
stringBuffer.append(s1.charAt(3-1));
stringBuffer.append(s1.charAt(10-1));
stringBuffer.append(s1.charAt(12-1));

/* Set the result to s2. */
s2 = stringBuffer.toString();
