Java 9 改進 Javadoc
Java 9 新特性javadoc 工具可以生成 Java 文檔， Java 9 的 javadoc 的輸出現在符合相容 HTML5 標準。
Java 9 之前的舊版本文檔
考慮以下檔代碼 C:/JAVA/Tester.java:
實例
/**
* @author MahKumar
* @version 0.1
*/
public class Tester {
/**
* Default method to be run to print
* <p>Hello world</p>
* @param args command line arguments
*/
public static void main(String []args) {
System.out.println("Hello World");
}
}
使用 jdk 7 的 javadoc 生成文檔：
C:\JAVA>javadoc -d C:/JAVA Tester.java Loading source file tester.java... Constructing Javadoc information... Standard Doclet version 1.7.0_21 Building tree for all the packages and classes... Generating C:\JAVA\Tester.html... Generating C:\JAVA\package-frame.html... Generating C:\JAVA\package-summary.html... Generating C:\JAVA\package-tree.html... Generating C:\JAVA\constant-values.html... Building index for all the packages and classes... Generating C:\JAVA\overview-tree.html... Generating C:\JAVA\index-all.html... Generating C:\JAVA\deprecated-list.html... Building index for all classes... Generating C:\JAVA\allclasses-frame.html... Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\index.html... Generating C:\JAVA\help-doc.html...
執行以上命令會再 C:/JAVA 命令下生成文檔頁面，如下圖所示：
Java 9 生成的文檔相容 HTML5 標準
使用 jdk 9 javadoc 命令中的 -html5 參數可以讓生成的文檔支持 HTML5 標準：
C:\JAVA> javadoc -d C:/JAVA -html5 Tester.java Loading source file Tester.java... Constructing Javadoc information... Standard Doclet version 9.0.1 Building tree for all the packages and classes... Generating C:\JAVA\Tester.html... Generating C:\JAVA\package-frame.html... Generating C:\JAVA\package-summary.html... Generating C:\JAVA\package-tree.html... Generating C:\JAVA\constant-values.html... Building index for all the packages and classes... Generating C:\JAVA\overview-tree.html... Generating C:\JAVA\index-all.html... Generating C:\JAVA\deprecated-list.html... Building index for all classes... Generating C:\JAVA\allclasses-frame.html... Generating C:\JAVA\allclasses-frame.html... Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\index.html... Generating C:\JAVA\help-doc.html...
執行以上命令會再 C:/JAVA 命令下生成文檔頁面，如下圖所示：
