Writing boilerplate getter and setter methods manually can take a lot of repetitive effort. Fortunately, Eclipse IDE lets you generate clean getters and setters for all your fields with just a few clicks or keystrokes.

Step 1: Declare Your Fields

Start with your standard Java class and declare your private member variables:

Open your Java class inside the Eclipse editor.
Declare your private fields (for example: private int id;, private String name;).
Save your file so Eclipse recognizes all member fields.

Step 2: Open the Source Menu

You can trigger the generation wizard using either the top menu or a quick context menu:

Right-click anywhere inside the editor window.
Hover over Source in the menu.
Click Generate Getters and Setters....
Tip: You can also use the top menu bar via Source > Generate Getters and Setters....

Step 3: Choose Fields and Insertion Point

In the dialog window that pops up:

Click Select All to create getters and setters for all variables, or check specific fields individually.
Select where you want the methods inserted (such as after the last member field).
Choose your preferred access modifier (typically public).

Step 4: Generate Your Methods

Click Generate (or OK). Eclipse immediately writes well-formatted getter and setter methods into your class, saving you time and avoiding manual typing errors.
