the javac element can set a java class up for compilation. Its srcdir and destdir indicate where the source java file is and where the resulting class file should go. A <classpath> subelement can point to where there may be any dependencies for the jar through its <fileset> element. |

Explain inheritance in ANT? |
The following tasks involve inheritance: <antcall> and <ant>. The ant task is used to invoke a target located in another build file. This allows a project to be scalable through child modules controlled through a master build file.
the inheritAll set to true property/attribtue of an <ant> element can tell the child build target to inherit all the properties of the master. |

How do you use an IF statement in ANT? |
IF logic is not native, so it needs to be added using a third party jar, like source forge's ANT-contrib.jar. You declare the namespace for the jar then you can use the namespace with the logic elements where needed in the project.
<project name="define-ac"> <taskdef resource="net/sf/antcontrib/antcontrib.properties"> <uri = "http://antcontrib.sf.net> . . </project>
<ac:if> <condition> <ac:then> do something </ac:then> </ac:if> |
