一,为减小 build.xml 文件的大小,使用XML实体

 

把属性的设置都放一个XML文件中

props.xml 文件

property name="build.dir" value="build" />

然后在 build.xml 文件中加入如下

DOCTYPE project []>

 

二,将多个目录的源文件编译到一个地方

 

javac destdir="build/classes">

    src path="src1"/>

    src path="src2"/>

javac>

 

三,保存构建时的信息

 

project default="init">

    target name="init">target>

    property environment="env" />

    property name="env.COMPUTERNAME" value="${env.HOSTNAME}" />

    propertyfile comment="Build Information" file="./buildinfo.properties">

        entry key="build.host" value="${env.COMPUTERNAME}" />

        entry key="build.user.name" value="${user.name}" />

        entry key="build.os.name" value="${os.name}" />

    propertyfile>

project>

 

四,去除属性文件的注释

 

属性文件:

# 这里是注释,会给过滤掉

build.dir = build

build文件:

copy file="props.properties" todir="sample">

    filterchain>

        striplinecomments>

            comment value="#" />

        striplinecomments>

    filterchain>

copy>

 

五,两个花俏的功能

 

1.声音提示

project name="Sound" default="all">

    property file="build.properties" />

    target name="init">

        sound>

            success source="${sound.dir}/success.wav" duration="500" />

            fail source="${sound.dir}/fail.wav" loops="2" />

        sound>

    target>

    target name="fail" depends="init">

        fail />

    target>

    target name="success" depends="init" />

    target name="all" depends="success" />

project>

 

2.进度条提示

project name="splash" default="init">

    target name="init">

        splash imageurl="http://java.chinaitlab.com/UploadFiles_8734/200610/20061021103415601.gif" showduration="5000" />

        sleep seconds="1" />

        sleep seconds="1" />

        sleep seconds="1" />

        sleep seconds="1" />

        sleep seconds="1" />

        sleep seconds="1" />

    target>

project>

Break or return from Java 8 stream forEach? Break or return from Java 8 stream forEach? Feb 07, 2025 pm 12:09 PM

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is
