HI! I'm studying java and I'm at a not very advanced level, could someone explain to me clearly how the static keyword works?

In Java most things are done using objects

these objects are created using classes.

you call methods with these objects that usually do certain work, such as updating the object's data etc.

when you say static you are telling java not to use an object

an example would be Math.abs(double a)

it's called in isolation of any particular object of the Math class

if it were non-static, I would be forced to use a Math object to call the method like this: Math math = new Math(); math.abs(-5.0);
