Java Function always returns 0


Question

Posted

code:

	public int getLastGotKill()
{
	Connection con = null;
	int last_pvp_time = 0;
	try
	{
		con = L2DatabaseFactory.getInstance().getConnection(false);
		PreparedStatement statement;
		statement = con.prepareStatement("select last_got_kill from characters where obj_Id=?");
		statement.setInt(1, getObjectId());

		ResultSet rset = statement.executeQuery();
		while(rset.next())
		{
			last_pvp_time = rset.getInt("last_got_kill");
			_log.info("last pvp time is : " + last_pvp_time);
		}
		rset.close();
		rset = null;
		statement.close();
		statement = null;
	}
	catch(Exception e)
	{
		if(Config.ENABLE_ALL_EXCEPTIONS)
			e.printStackTrace();
	}
	finally
	{
		CloseUtil.close(con);
		con = null;
	}
	return last_pvp_time;
}

 

why does this return always 0 ? i am sure that the column last_got_kill is not zero for the selected player

Bhe my bad,you used other name for initial variable.

 

Cleaned version is (java 7)

 

	public int getLastGotKill()
{
	int lastGotKill = 0;
	try (Connection con = L2DatabaseFactory.getInstance().getConnection(false))
	{
		PreparedStatement statement = con.prepareStatement("SELECT last_got_kill FROM characters WHERE obj_Id=?");
		statement.setInt(1, getObjectId());

		ResultSet rset = statement.executeQuery();
		while(rset.next())
		{
			lastGotKill = rset.getInt("last_got_kill");
			_log.info("lastGotKill is : " + lastGotKill);
		}
		rset.close();
		statement.close();
	}
	catch(Exception e)
	{
		if(Config.ENABLE_ALL_EXCEPTIONS)
			e.printStackTrace();
	}
	return lastGotKill;
}

 

About your problem, do you see the log.info while executing that method ? Are you SO SURE about the variable being different of 0 ? If you edited at hand you have to save the change or if you used a query to save it, the query has to be correct.

 

Are you sure you use getLastGotKill() on the good instance ? (killed != killer).

Are you sure last_got_kill (on your sql) is an int type ?

    • Let me see if I understand correctly, older gentlemen, when a newcomer shows up to create modern things with the help of AI, doing what you charge them to do, you point the finger and laugh. I believe that's why everything is stagnant. The product isn't for programming experts, it's for newcomers. Don't buy from you if they can do it themselves using this base. You're going to deliver a similar product, maybe even worse than this one, so why are you complaining? PowerShell, as you well know, started with it, then came new platforms and new apps, new creation models, all with different languages; I chose the simplest one for my taste. This is about being organized and knowing how to choose the right words for each situation. It's not 100%, but it already gives a good impression. Nothing is 100%, so a topic written by AI, and all the code that you charge an absurd amount for to prohibit and sell hacks, could be open source so that everyone can create new practices, new models, new information for passing packets, prohibiting the use of cheats that cause server owners to break so much. Let's remember that the Admin doesn't always shut down the server; it's the players who find problems and take advantage by buying and reselling items, and they say that the GM shuts down the server every week, but that's a lie. What they do is duplicate items with packages and sell them, but perhaps this could give some future developers a starting point to create their own protection following the model in the initial documentation. Because none of you answer a question from a newbie, you think you're superior because you have knowledge, but with AI, people like that can have the same knowledge as you, but with less practice. And if they practice a lot, 10,000 hours, they can be as good as all of you older developers in the L2J field.
