IntelliJ is it possible to add @Overrrides to all methods of a particular interface?

Question

I have created an interface, with about 30 methods and implemented in 30 classes.

I want to add @Override to each of the implementations, but i would like not to do it by hand.

How can IntelliJ help me?

interface looks like this:

public interface PreviewObjectTests {     void testGetName();     void testGetType();     //... 30 similar methods } 

implementation code:

public class PreviewObjectAccountTest implements PreviewObjectTests {      //I want to add @Override here!     @Test public void testGetName() {         assertThat(...);     }      //I want to add @Override here!     @Test public void testGetType() {         assertThat(...);     }      //...30 similar methods   }

Easily done with Alt+Enter intention, then press Right arrow for the sub-menu:

For IntelliJ:

1. Check if you have "Missing @Override annotation" checked inside Preferences -> Project Settings -> Inspections -> Inheritance issues.
2. Use Analyze -> Inspect Code
3. Find Inheritance issues -> Missing @Override annotation inside "Results for Inspection Profile" window.
4. Apply fix "Add @Override annotation"
