I want to compare the 2 images(images of people)and want a result that these are of same person or not(By Face recognization).I have to do this for millions of images so I cannot do it manually .Is there any api for android that can be used in my app.
You could use Camera.Face or FaceDetector.Face class. Take parameters of face on both photos and compare their parameters using e.g. eyesDistance(). If those parameters quite the same -> its the same person.

Is there a way in Java to create a List implementation that has a timeout/eviction policy for items contained in the list? Something along the lines of:
List<SomeObject> myList = new TimeoutList<>(10, TimeUnit.SECONDS);
so that items entered into the list will be automatically evicted after the given time. I know about the Guava Cache, but a cache is a Map and will not maintain the order of the items entered.

I want to use libdx and box2d, what things I can simulate with box2d or libgdx and I need something that can be useful in everyday life, it can be on any platform thanks.
You can simulate the effect of gravity on objects having different shapes and mass. You could allow the user to place objects and make the user specify the shape, mass ans size. then the user can watch as gravity causes the shapes to move in interesting patterns.

I have a table in my database. I am using jdbc to use this database. I want to update a particular data by subtracting it to some value.
Suppose a student with name xyz is there. Currently his marks in a subject is 50. I want to delete it by 10, then what would be the syntax? I am new to SQL.
More or less:
update students
set mark = mark - 10
where name = 'xyz'
Can't give a better answer than that, as your question is very limited in useful and concrete information. I'm sure you'll figure it out.
