*/
2. 具体类功能注释
示例如下:
/**
* Class <code>Object</code> is the root of the class hierarchy.
* Every class has <code>Object</code> as a superclass. All objects,
* including arrays, implement the methods of this class.
*
* @author unascribed
* @version 1.61, 01/23/03
* @see java.lang.Class
* @since JDK1.0
*/
public class Object {}
注释结构:
/**
* 类 <code>{类名称}</code>{此类功能描述}
*
* @author {作者}
* @version {版本,常用时间代替}
* @see java.lang.Class
* @since JDK{jdk版本}
*/
public class Object {}
3. 类变量注释
示例如下:
/** The value is used for character storage. */
private char value[];
注释结构:
/** {此值是用来存储/记录什么的}*/
private String str ;
4. 类方法注释
示例如下:
/**
* Returns a new string that is a substring of this string. The
* substring begins with the character at the specified index and
* extends to the end of this string. <p>
* Examples:
* <blockquote><pre>
* "unhappy".substring(2) returns "happy"

* "emptiness".substring(9) returns "" (an empty string)
* </pre></blockquote>
*
* @param beginIndex the beginning index, inclusive.
* @return the specified substring.
* @exception IndexOutOfBoundsException if
* <code>beginIndex</code> is negative or larger than the
* length of this <code>String</code> object.
*/
public String substring(int beginIndex) {
return substring(beginIndex, count);
}
注释结构:
/**
* {方法的功能/动作描述}
*
* @param {引入参数名} {引入参数说明}
* @return {返回参数名} {返回参数说明}
* @exception {说明在某情况下,将发生什么异常}
*/
public String substring(int beginIndex) {
return substring(beginIndex, count);
}
5. 类方法中代码块注释
