注释和嵌入文档

• 代码如下

//: Property.java
package com.isflee.first_java_app;

import java.util.Date;
import java.util.Properties;

//17章会用到
/** The first Thinking in Java example program.
 * Lists system information on current machine.
 * @author Bruce Eckel
 * @author http://www.BruceEckel.com
 * @version 1.0 */
public class Property {

    /** Sole entry point to class & application
     * @param args array of string arguments
     * @return No return value
     * @exception exceptions No exceptions thrown
     */
    public static void main(String [] args){
        System.out.println(new Date());
        Properties p = System.getProperties();
        p.list(System.out); System.out.println("--- Memory Usage:");
        Runtime rt = Runtime.getRuntime();
        System.out.println("Total Memory = " + rt.totalMemory() + " Free Memory = " + rt.freeMemory());
    }

}

• 可以用 javadoc Property.java 命令生成对应的文档
