Hi,

PL/SQL can be executed from JDBC using CallableStatement or PreparedStatement, like ordinary SQL
Here is a simple example:




You can bind values (use parameters) in your PL/SQL query

If the stored procedure is already there then better to use the CallableStatement directly. No need of writing the same stored procedure inside the connection.prepareStatement(). Directly use the CallableStatement with the stored procedure name
Check the link Call Stored Procedure from Java

Yes, it definitely can be run using a Statement. However if it would be used over and over again with just the differences in literal values, then by using the PreparedStatement or CallableStatment you get the benefit of:

1) Sql injection prevention (no arbitrary strings concatenated directly into your SQL code), and

2) faster processing and higher scalability (reusing the PreparedStatement with different values of bind parameters generally saves on database processing by skipping the parse phase, which can be resource consuming and non-scalable in Oracle).
