Is there any way to develop a custom execution planner for queries?
As execution plan I refer to
https://neo4j.com/docs/cypher-manual/current/execution-plans/
I want to develop an execution planner to modify the order with which match clauses are executed.
For example, is the query only specifies a list of edges, I would like to choose the order with which edges are matched.
Thank you.
There is no built-in way to plug in your own planner implementation.
However, since the code is open source, you could always fork the repo and modify the planner yourself.

I start working with a project and want to start project with Selenium. Please suggest me how can i start write script in Eclipse with Java?
What you want JavaScript or Java? Because your title and body are different.
If you want to do using Java then you know as you told that you are working. Just I want to give you one point for start up project that always use class/name/value/others use for Xpath, NEVER use ID. Because for every build the ID will changed.
If you want to set up your project using JavaScript then use WebDriverIO or WebDriverJS. You can google for details on that.

I have a java application which needs the 'TIME' last time my app has run.
i am running jar manually.Where should this last time run info can be stored .Should i store the last run time on file or some environment variables or some other?Please suggest best way of doing this.
A straight-forward way would be with the Preferences API. You won't need to care how the data is actually stored, or where.

I'm new to Java and I completely have no idea how to do this. I have two separate Java applications and I want to sent a double value from the first application to the second application in order to use it in a calculation method then send the result back to the first application.
what is the easiest/ shortest way to do that?
Create .jar of your first application which contains your calculation method.
And use this .jar as library in your second application.
This is the easiest way

I want to generate sql queries at run time, user drag and drop the schema from UI like table name no of fields, joining, conditions. In back end I want to build a sql query by using these input from front end and send the build sql query to front end how to achieve this and which API i need to use.
The most common solution for this is criteriaQuery, but you should seriously consider QueryDSL. It has same functionality as criteria (including dynamic query building), but is more maintainable and readable.

I am considering using JPPF for a application which runs a set of tasks in parallel. I was wondering if any one has had any recent experience using the framework. In particular I am interested in
1. Aspects around "robustness" for example recovery from failure of nodes.
2. Running tasks on 500+ nodes.
3. Network traffic
