public class JDBCDeleteDemo {
public static void main(String[] args) {
Connection conn = null;

try {
conn = JDBCUtils.getConnection();
stmt = conn.createStatement();
String sql = “delete from user where id = 3”;
int sum = stmt.executeUpdate(sql);
System.out.println(sum);
}catch (Exception e){
throw new RuntimeException(e);
}finally {
JDBCUtils.release(conn,stmt,null);
}
