Java how to make methods in intellij keyword

To make a method a keyword in IntelliJ IDEA, you can use the @Test annotation from the JUnit library.

Here is an example of how you can make a method a keyword in IntelliJ IDEA:

import org.junit.Test;

public class MyClass {
    @Test
    public void testMethod() {
        // method body
    }
}

In this example, the @Test annotation is used to mark the testMethod method as a test method. When the testMethod method is invoked, it will be highlighted as a keyword in IntelliJ IDEA.

Keep in mind that the @Test annotation is part of the JUnit library, which is a popular testing framework for Java. To use the @Test annotation, you will need to add the JUnit library to your project dependencies.

You can also create custom annotations in Java and use them to mark methods as keywords in IntelliJ IDEA. For example:

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Keyword {
}

public class MyClass {
    @Keyword
    public void keywordMethod() {
        // method body
    }
}

In this example, the @Keyword annotation is defined and marked with the @Retention and @Target annotations to specify that it can be applied to methods and that it should be available at runtime. The keywordMethod method is then marked with the @Keyword annotation. When the keywordMethod method is invoked, it will be highlighted as a keyword in IntelliJ IDEA.
