JAVA代码注释范例
作者: 周建东 日期: 2007-10-18 03:31
字体大小: 小 中 大
整个类文件注释示例如下:
/*
* @(#)Object.java 1.61 03/01/23
*
* Copyright 2003 Sun Microsystems, Inc. All rights reserved.
* SUN PROPRIETARY/CONFIDENTIAL. Use is subject to license terms.
*/
package java.lang;
注释结构:
/*
* @(#){类名称}.java {创建时间}
*
* {某人或某公司具有完全的版权}
* {使用者必须经过许可}
*/
package java.lang;
2. 具体类功能注释
示例如下:
/**
* Class Object is the root of the class hierarchy.
* Every class has Object 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 {类名称}{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.
* Examples:
*
* "unhappy".substring(2) returns "happy"
* "Harbison".substring(3) returns "bison"
* "emptiness".substring(9) returns "" (an empty string)
*
*
* @param beginIndex the beginning index, inclusive.
* @return the specified substring.
* @exception IndexOutOfBoundsException if
* beginIndex is negative or larger than the
* length of this String 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);
}
注释结构:
/*
* {功能描述}
*
* {具体实现动作}
*/
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);
}
