What is the use of setlayout method?


The setLayout() method allows you to change the layout of a container, which is often a JPanel, to a different layout, such as FlowLayout, BorderLayout, GridLayout, null layout, or any other layout you choose. The layout manager assists in the arrangement of the components contained within this container.


It’s also important to understand what the layout manager is for?

It is an object that implements the LayoutManager interface* and is responsible for determining the size and position of the components within a container. Despite the fact that components might provide size and alignment clues, the layout manager of a container has the last word on the size and position of the components included within the container.


In addition to the foregoing, what does setLayout null mean?

Null layout means that you must do all of the work in your code; otherwise, you will receive an error. There is no layout manager to assist you. It also illustrates when you would utilise abolute positioning versus when you would employ a layout manager in your design.


In this regard, how do I make use of FlowLayout?

To start the applet, simply click on the image. The applet will display in a new browser window after you click on it. FlowLayout arranges components in a row and sizes them according to their preferences. If the horizontal space available in the container is insufficient to accommodate all of the components in a single row, FlowLayout employs multiple rows.
