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"
* "Harbison".substring(3) returns "bison"
* "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

示例如下:

/*
* 调用持久化类，将数据保存到库
*
* 判断是添加，还是修改
*/
boolean ifSucc = false;
if(request.getParameter("YINGLI_ID")==null){
String GUID = new RandomGUID().toString();
stressTestDataBean.setUSER_ID(Integer.toString(userId));
stressTestDataBean.setSIGN_ISBN((String)vSectNum.get(0));
stressTestDataBean.setSHENHE_JIEGUO("0");
stressTestDataBean.setGUID(GUID);
stressTestDataBean.setCREATE_DATE("getdate()");
stressTestDataBean.setSTATE("A");
ifSucc = StressTestDataDao.addStressTestData(db,stressTestDataBean);
}else{
ifSucc = StressTestDataDao.mendStressTestData(db,stressTestDataBean);
}
