Difference between getSeed() and generateSeed() functions in java's SecureRandom class?

What is the difference between functions getSeed() and generateSeed() in java's SecureRandom class? Both looks same except that getSeed() returns static byte[] and generateSeed() returns only byte[].

See the documentation:

This method is only included for backwards compatibility. The caller is encouraged to use one of the alternative getInstance methods to obtain a SecureRandom object, and then call the generateSeed method to obtain seed bytes from that object.

The SecureRandom.getSeed(int) JavaDoc explicitly says

This method is only included for backwards compatibility. The caller is encouraged to use one of the alternative getInstance methods to obtain a SecureRandom object, and then call the generateSeed method to obtain seed bytes from that object.
