下面是一个来自Oracle的JavaDoc注释示例:

/**

 * The url argument must specify an absolute {@link URL}. The name
 * argument is a specifier that is relative to the url argument. 
 * <p>
 * This method always returns immediately, whether or not the 
 * image exists. When this applet attempts to draw the image on
 * the screen, the data will be loaded. The graphics primitives 
 * that draw the image will incrementally paint on the screen. 
 *
 * @param  url  an absolute URL giving the base location of the image
 * @param  name the location of the image, relative to the url argument
 * @return      the image at the specified URL
 * @see         Image

 public Image getImage(URL url, String name) {
        try {
            return getImage(new URL(url, name));
        } catch (MalformedURLException e) {
            return null;

基本格式可以通过以下两种方式自动生成:

将光标置于方法上方，并键入/** + Enter 将光标定位在方法名上，按Alt + Enter >，单击Add JavaDoc

另一种添加javadocs注释的方法是按下:Ctrl + Shift + A >>显示一个弹出>>类型:添加javadocs >> Enter。 Ctrl +衬衫+ A:命令查找(自动补全命令名)

在Android Studio中，你不需要插件。在Mac上，只需打开Android Studio ->单击顶部栏中的Android Studio ->单击preferences ->在列表中找到文件和代码模板->选择包含->构建它，并将在所有项目中持久存在

添加Javadoc

/** +返回 在方法名称中设置光标->选项+返回->添加Javadoc

要在方法声明之前输入/**键并按Enter生成注释。它将生成javadoc注释。

例子:

/**
* @param a
* @param b
*/

public void add(int a, int b) {
    //code here
}
