There are a lots of layout manager available, it depends upon the type of components you use in your program , if you are using the simple buttons and text boxes , it is advisable that you use the flow layout , or else you can use the Border layout as well . But I do not know why many people now a days make use of Null layout, in which they pass the x and y co-ordinates of the of the components in order to place them in the exact location.

A layout manager is an object that generally deplyes and implements the LayoutManager interface and decides the size and location of the components inside a container. Although components can give size and position hints, a container's layout manager has the concluding say on the size and location of the components inside the container.

As a regulation, the lone containers whose layout managers you require to concern about are JPanels and content panes. Every JPanel object is initialized to make use of a FlowLayout, if not you mention another way when creating the JPanel. Content panes make use of BorderLayout by default. If you are not fond of the default layout manager that a panel or content pane uses, you are permitted to modify it to a diverse one. However, if you are not using JToolBar, the FlowLayout and BorderLayout managers are just helpful for prototyping. Any actual application will require to reset the layout manager. Again, you must make use of an suitable tool to do this, rather than coding the manager by yourself.
You can set a panel's layout manager use the JPanel constructor. For example:

JPanel panel = new JPanel(new BorderLayout());
