setting path variables

asked by MeghaB

you need to check if PATH environment variable points to the java executables directory.

Open command prompt

Run ‘set path’. This will print the current value of path environment variable. You can see the list of all the directories added. Check if Java sdk path is added or not. If it’s added you should be able to see something like below.
c:\>set path
Path=C:\Program Files (x86)\Windows Resource Kits\Tools\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Quarantine\;C:\Program Files\Perforce;C:\Program Files\Microsoft Network Monitor 3\;c:\Program Files\Java\jdk1.7.0_17\bin

answered by VikasMishra, [ Aug, 2017 ]

Hi,regarding to your first question if you are telling to clear a browser cache using java.No,there is no such feature or code in any programming lanuage. There's no way a browser will let you clear its cache. It would be a huge security issue if that were possible. This could be very easily abused - the minute a browser supports such a "feature" will be the minute I uninstall it from my computer.

What you can do is to tell it not to cache your page, by sending the appropriate headers or using these meta tags:

<meta http-equiv='cache-control' content='no-cache'>
<meta http-equiv='expires' content='0'>
<meta http-equiv='pragma' content='no-cache'>

asked by vishalparmar

Annotation processing is a tool build in javac for scanning and processing annotations at compile time. You can register your own annotation processor for certain annotations.
An annotation processor for a certain annotation takes java code (or compiled byte code) as input and generate files (usually .java files) as output. What does that exactly means? You can generate java code! The generated java code is in a generated .java file. So you can not manipulate an existing java class for instance adding a method. The generated java file will be compiled by javac as any other hand written java source file.

answered by VikasMishra, [ Jul, 2017 ]

Annotations have a number of uses, among them:

Information for the compiler — Annotations can be used by the compiler to detect errors or suppress warnings.

Compile-time and deployment-time processing — Software tools can process annotation information to generate code, XML files, and so forth.

Runtime processing — Some annotations are available to be examined at runtime.
