What is a Perspective?

A perspective is a visual container that includes a series of views and content editors. The default perspective is called Java.

An Eclipse window can open multiple perspectives, but only one perspective can be active at a time.

Users can switch between two perspectives.

Operating Perspectives

Open the perspective dialog by selecting "Window" and then "Open Perspective > Other".

The perspective dialog displays a list of available perspectives.

This list of perspectives can also be opened via the perspective button on the toolbar.

In most cases, Java developers use the Java perspective and the Debug perspective. You can switch freely via the perspective name on the toolbar.

Right-click the perspective name on the toolbar and select "Close" to close the perspective.

We can customize the perspective window to set up the perspective we want.

Click "Windows" on the menu bar => "Customize Perspective" => A popup window appears, where you can select the content you want to set in "Submenus".
"New" => Set up your new menu, select the most commonly used file types you need to create.
"Show Views" => In the layout of your custom view, which windows will appear when you switch to your own view. Set according to your habits.
"Open Perspective" => In the view switching menu, which views are available to choose from.
After setting everything, save your custom perspective. Windows => Save Perspective as, then name your custom perspective and save it.
