Show name on the top left in Minecraft?

I'm about to program a Hack Client for Minecraft with Eclipse and I'd like to know how to show the name ingame in the top left corner (not the name of the program).

Do you mean the player name of the person using the client or the account you are logged in with?

Ne my name from the client

Minecraft.getMinecraft (). McFontRenderer.drawString ("Name", x, y);

somehow that's how it went

Or so

Minecraft.getMinecraft (). FontRenderer.drawStringWithShadow ("Name", 2, 2, 0x000000);

And in which class?

If that's how it starts I'm tired, sry
