IntelliJ IDEA 13.1 Web Help

You can generate accessor and mutator methods (getters and setters) for the fields that exist in your classes. IntelliJ IDEA generates getters and setters with only one argument, as required by the JavaBeans API.

The getter and setter method names are generated by IntelliJ IDEA according your code generation naming preferences.

In this section:

To create accessor and mutator methods
  1. On the main menu, choose Code | Generate.
    Alternatively, right-click the editor and choose Generate on the context menu, or use Alt+InsertAlt+InsertAlt+InsertAlt+InsertAlt+InsertAlt+InsertCtrl+N or Alt+InsertAlt+InsertAlt+InsertCommand N or Control EnterControl N or Control EnterCommand N or Control Enter keyboard shortcut.
  2. In the pop-up list that is displayed in the editor, select one of the following options:
    Getter
    Accessor method for getting the current value of the selected fields.
    Setter
    Mutator method for setting specified values to the selected fields.
    Getter and Setter
    Both methods for the selected fields.
  3. In the Choose Fields to Generate Getters and Setters dialog box, select the desired fields.

    Note

    If getters and setters for a field already exist, this field is not included in the list.

  4. Click OK.

Example 1

Consider the following code:

      public class MyClass {
    int aInteger;
}
    

In the Naming section of the Code Generation page, parameter prefix is set to my, and parameter suffix to Param.

After generating the getter and setter the following code will be produced:

      public class MyClass {
    int aInteger;
 public int getAInteger() {
     return aInteger;
 }
 public void setAInteger (int myAIntegerParam) {
     aInteger = myAIntegerParam;
 }
}
    

Example 2

However, if a is specified as a field prefix in the Code Generation page, then it will not take part in the generation of the method and parameter names:

      public class MyClass {
    int aInteger;
    public int getInteger() {
        return Integer;
    }
    public void setInteger (int myIntegerParam) {
        aInteger = myIntegerParam;
    }
}
