I don't know if this is THE four ways, but here are four possible ways:
Temperature/Color (amounts to the same thing)
Size
Population ("metallicity" is essentially a different description of pretty much the same thing)
Mass
Characteristics used to classify stars include color, temperature, size, composition, and brightness.
The 4 things a star is classified by is it's color, size, temperature, and composition.
The correct classification for the stars is O,B,A,F,G,M,K.
size, color, distance and shape
the four ways are front back left or right

wavelength, amplitude, frequency, and wave speed
Thermal (Heat) Kinetic (Movement) Nuclear Sound

There are four ways to classify a mineral:They have a crystal structureThey are formed in natureThey have a definite chemical makeupThey are a solid
They are usually classified by their temperature.
Protostar formation - The Birth of a starMain sequence - When it converts hydrogen into energyPost main Sequence - When they die.
Using the sun moon and stars
