SQL increment id, filling first line of database - eclipse

Question

I habe a sqlite database in java (eclipse) with the library sqlite-jdbc-3.16.1.jar.
I have 5 rows in table1: id(ID Integer PRIMARY KEY AUTOINCREMENT), name, row3, row4, row5
I want to insert name, row3 and row4 and the id to increment itself.
public static void insertTest(String name, byte[] contentRow3, byte[] contentRow4) {
String sql = "INSERT INTO table1(name, contentRow3, contentRow4) VALUES(?,?,?)";
try (Connection conn = connect();
PreparedStatement pstmt = conn.prepareStatement(sql)) {
pstmt.setString(2, name);
pstmt.setBytes(3, contentRow3);
pstmt.setBytes(4, contentRow4);
System.out.println("Added new Person to DB");
pstmt.executeUpdate();
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}
Error : Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3
What is the problem here?

Answer 1

Placeholders in Java prepared statements begin at index 1, not 2. I expect that the following corrected code should work:
try (Connection conn = connect();
PreparedStatement pstmt = conn.prepareStatement(sql)) {
pstmt.setString(1, name);
pstmt.setBytes(2, contentRow3);
pstmt.setBytes(3, contentRow4);
System.out.println("Added new Person to DB");
pstmt.executeUpdate();
} catch (SQLException e) {
System.out.println(e.getMessage());
}
The exception you are getting is complaining that index position 3 is out of bounds. Most likely, under the hood when you did pstmt.setBytes(3, contentRow4) this translated to accessing the fourth array element, which would be index 3 assuming the array indexing is zero based.
