Importing the library( Box2D )

It is important to keep two things in mind:

Axis orientations: the coordinate (0, 0) with the G1 is typically the upper left corner of the screen, while (0, 0) in Box2D is the bottom left corner of the screen.
The other thing are dimensions: Box2D works fine with dimensions from 0.1 to 10 times the typical earth dimensions such as density, friction, gravity, …. Internally the engine is using meters and we will need to convert them to pixels. If we say, 1 meter shall be 10 pixels, that function could look like this:

public Vec2 toScreen(Vec2 pos) {
pos.x = pos.x*10;
pos.y = 480 - (pos.y*10);
return pos;
}
