Java learning notes-swing interface with box Layout

These four methods are mainly used.

Createhorizontalbox()

Create a component that displays its components from left to rightBox.

Createhorizontalstrut(INT width) // you can use this method to control the intermediate interval between left and right parts.
Create an invisible, fixed-width component.

Createverticalbox()

Create a componentBox.

Createverticalstrut(INT height) // you can use this method to control the intermediate interval between the upper and lower parts.
Create an invisible, fixed height component.

As follows:
