PatternFly Java is a Java implementation of [PatternFly 5](https://www.patternfly.org) based on GWT/J2CL and [Elemento](https://github.com/hal/elemento). Its goal is to provide an easy-to-use, elegant, and efficient API to build complex web applications with PatternFly in Java. The following code snippet gives a taste of what PatternFly Java looks like:

import org.patternfly.component.button.Button;

import org.patternfly.core.Aria;

import org.patternfly.core.Modifiers.Inline;

import org.patternfly.core.UnderDevelopment;

import org.patternfly.handler.Callback;

import org.patternfly.layout.Classes;

import static org.patternfly.layout.Classes.truncate;

import static org.patternfly.layout.PredefinedIcon.times;

public class Alert extends BaseComponent<HTMLDivElement, Alert> implements Inline<HTMLDivElement, Alert> {

// ------------------------------------------------------ factory methods

public static Alert alert(AlertType type, String title) {

return new Alert(type, title);

}

// ------------------------------------------------------ instance

public enum AlertType {

custom(bell, Status.custom, "custom alert"),

info(infoCircle, Status.info, "info alert"),

public class Brand extends BaseComponent<HTMLImageElement, Brand> {

// ------------------------------------------------------ factory methods

package org.patternfly.core;

import java.lang.annotation.Retention;

import java.lang.annotation.RetentionPolicy;

import java.lang.annotation.Target;

import static java.lang.annotation.ElementType.TYPE;

@Retention(RetentionPolicy.SOURCE)

@Target(value = TYPE)

public @interface UnderDevelopment {

}
