Oracle JDBC (10g) reading clobs -- best practices

Question

What is the better approach using oracle 10g to save clobs:
#1) This:
PreparedStatement pstmt = conn.prepareStatement
//Create the clob for insert
Clobs Clobs = new Clobs();
CLOB TempClob = Clobs.CreateTemporaryCachedCLOB(conn);
java.io.Writer writer = TempClob.getCharacterOutputStream();
writer.write(Description);
writer.flush();
writer.close();
#2) Or this:
OraclePreparedStatement pstmt = (OraclePreparedStatement)conn.prepareStatement
pstmt.setStringForClob()
According to my notes, it is #2.
What is the better approach to read clobs:
#1) Stream the clob
//Get character stream to retrieve clob data
Reader instream = ClobIn.getCharacterStream();
//Create temporary buffer for read
char[] buffer = new char[10];
//Length of characters read
int length = 0;
//Fetch data
while ((length = instream.read(buffer)) != -1){
for (int i=0; i<length; i++){
Contents += buffer;
//Close input stream
instream.close();
//Empty LOB
ClobIn.empty_lob();
#2) Or this:
Simply use rs.getString() to get your clob contents. This will return the entire clob and will not truncate.
Im just confused on the best practices for performance/memory allocation and I keep reading people saying different.

Check chapter 16 of "PL/SQL Programming", by Oracle Press, for a starter.
Then have a look at this link - I found it helpful: http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/LOBSample/LOBSample.java.html
