when you configure ip addresses for different interfaces like 10.1.1.1 for wlan and 10.2.1.1 for ether 2.do you also create a bridge for the interfaces and add them to ports.

Not unless you want to bridge the interfaces. Bridging interfaces puts them on the same broadcast domain (the same network). Also, when you bridge interfaces the IP address gets added to the bridge, not the interfaces. And you add interfaces to bridges, not the other way around.

When you make a bridge, you assign whatever IP address(es) you want to the bridge. Assigning IP addresses to the physical interfaces that are part of the bridge will break things.

Assigning IP addresses to the physical interfaces that are part of the bridge will break things.

It should not break anything. Bridge will simply inherit IP addresses from interfaces assigned as bridge ports.
