I have worked on Lambda functions in Jython. It's a very cryptic code that achieves something which requires lengthier code.
When I had a first look at Java 8 Lambda expression, it is also very similar to Jython's lambda function.
I need to deep dive, I am at surface level.
But, is my understanding correct?

Hi,

Is it possible to have more than one line (line break, multi-line label) in Label (AWT).
I know you can give in JLabel.

But I am asking in Label.

Thanks,

Guys,

This question may not even fit into Java - General category.
Please throw your ideas if you wish.

I am actually into the development of uninstalling a software product.
I am giving a fresh look into this requirement from the following perspectives:
- From end user perspective
- use of use, no ambiguities, not much interview questions, and data protection (the data created out the software should be kept intact, only the s/w bits need to be removed).
- From developers perspective
- uninstaller software should be extended
- Loose coupling and high cohesive
- Proper design and design patterns
- Choosing the efficient technologies

Is any other things I need to consider?

Thanks,
Guru

Superb Paul.

thanks for the simple explanation. Yes, I have tried out a sample program with this.

Thanks a lot,
Guru

Is it possible that some popups come if the application is currently running and any changes on jar on the server side?

I have a stand-alone java application (swing based).
I want the pop-up to come up from the customer (where the application is running) machine, if any new updates (in terms of new jars/modified jars) to alert and ask the customer to apply the fix/patch, whatever you call.
For this scenario, jnlp/webstart will be useful or think about any other java mechanism?

I have a simple GUI.
I have a JTable with some rows and columns.
I have a JButton.
Default JTable behaviour is that -
if you press "TAB" in the last cell, the cursor goes to the first cell.
But what I need is, if you press "TAB" in the last cell, the focus should go out of JTable and select the JButton.

How to achieve this?

Hi,

System.getenv("LD_LIBRARY_PATH");
This prints the value of $LD_LIBRARY_PATH in unix.

How to set "LD_LIBRARY_PATH" through java?
System.setProperty("LD_LIBRARY_PATH",path) is not working.

There is no System.setenv()

Hi,

I have two VARRAYS.
Is there any quick way to compare them?

This is for ORACLE DATABASE.

Thanks,

I read somewhere that Integer.MAX_VALUE (2^31-1) is the way.
Is it true?

Thanks,
