Layout Manager in JAVA

Layout Managers

java.awt and javax.swing packages contains Many Layout Manager classes.

Layout Manager determines the Way in Which That Component are arranged

in the container. All the JAVA Container Contains Their own Default Layout

Manager so in your JAVA Program if you not Specify any java Container,

JAVAcompiler Will use the Default layout manager. you can also Select

different layout Manager.

Why We Need To Define The Layout Manager

One Question may be coming in your mind Why we need to Specify the

Layout Manager ? We can use the JAVA Component by Specifying the

Location and Size also so Why We need Layout Manager..?? so the

reason is to ensure that JAVA GUI Elements are displayed properly in

every possible JAVA Environment. Layout manager Automatically Adjust

the size and Position of the components to fit According the Size of the

Screen. Suppose if your Windows Size is less and you Fixed the Size

and Location of Each Component, Then There is a Possibility of the

Overlapping of the Components.
