run() is the interface method a Runnable implements

runOnUiThread(Runnable action) takes a Runnable which implements the run() method and executes it on the MainThread.

Views can only be changed from the MainThread therefore run() executed from every other thread will result in an error

runOnUiThread internally gets the Main or UI Thread and runs the code written inside it on the Main/UI thread.

run method initializes a new thread in the Executor Pool which is randomly assigned to it. Hence you cannot run UI changes code in a run method.
