Arranging components on user interface :

The AWT contains a basic layout managers:
1- FlowLayout: This is the default layout manage. Components are added to the container from left to right. When there is nor more space in a row, components get added in the next row from left to right and so on.
FlowLayout f = new FlowLayout();
FlowLayout f = new FlowLayout(align);
FlowLayout f = new FlowLayout(align , hgap, vgap);
Hgap : that between components and pixels
Vgap : that gap between components and pixels.

2- GridLayout: arranged I nthe form of a grid consisting of rows and columns. Components are added from left to right and top to bottom in the grid.
Default gap between the components is zero pixels in both vertical and horizontal directions.
3- BorderLayout: the container is divided into five sections : north, south , east , west and center. The central components is the largest and other components surrounding it will be similar. A border layout is created by either using zero argument constructor or the one which takes hgap and vgap as a srgumetns.
Panel p = new Panel();
GridLayour g = new GridLayour(3,3);
p.setLayout(g);
p.add(c1);
p.add(c2);
c1, c2 are the components added to the panel p.
4- CardLayout: this is a group of containers or components that are displayed one at a time. Each container in the group is called as a card.
CardLayout c = new CardLayout();
5- GridBagLayout: this is a extension of the grid layout manager. Agrid bag layout differs from grid layout.
A components can occupy more than one cell in the grid.
The components between different rows and columns do not have to be equal.
Components inside grid cells can be arranged in different ways.

Frames : these are subclasses of a class called windows. The fromae calss provides a window with title bar, close boxes and other windows features. Dialog boxes are similar to frames , but they don’t have a title . frames are containers similar to panels. The default layout form frames is Border Layout.
Use resize() method to provide a size
