There are two kind of loops in Java, for and while.
For

The for loop has three sections:

for (int i = 0; i < 3; i++) {}

First section runs once when we enter the loop.

Second section is the gate keeper, if it returns true, we run the statements in the loop, if it returns false, we exit the loop. It runs right after the first section for the first time, then every time the loop is finished and the third section is run.

The third section is the final statement that will run every time the loop runs.
