I have one SDK that is available in Java and another SDK that is available for .Net and would like to write a single application that interfaces with both of them. I imagine I will need to use a cross platform communication framework that can support named pipes (or other in memory communication), what is the best choice?
After some more research I found Hessian -- does anyone know anything about the maturity of this project?
Using JNI can we pass custom data types from Java to C (or vice versa)? I see a mapping of primitive datatypes to types in C however not too sure if we can send across our own data types (e.g. Send across or return an Employee object or something!).
I see many similar questions, however I want to find the Username of the currently logged in user using Java.
Its probably something like:
System.getProperty(current.user);
But, I'm not quite sure.
Given the following code:
public class Test {
public void method(Object o){
System.out.println("object");
}
public void method(String s) {
System.out.println("String");
}
public void method() {
System.out.println("blank");
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Test test=new Test();
test.method(null);
}
}
Java prints "String". Why is this the case?
I need a java program to get the current date without timestamp
Date d = new Date();
gives me date and timestamp
But i need only date, without timestamp. I use this date to compare with another date object that does not have timestamp.
on printing
System.out.println("Current Date : " + d)
of d it should print May 11 2010 - 00:00:00 .
hi there,
I'm looking for an solution to generate a checksum for any type of java object, which remains the same for every exection of an application which produces the same object.
I tried it with object.hashcode(), but as I read in the api
....This integer need not remain consistent from one execution of an application to another execution of the same application.
thank you, best regard alex
I need to use a few Cyrillic characters in a Java file and in order for Eclipse to allow me to do so I need to change the encoding for that file (currently to UTF-8).
Are there any possible problems that this could cause?
Hi crew,
I'm searching for a tool, which converts a jsp file into a java file without using a server like tomcat or something else.
Can anyone help me out?
This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth.
A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?
I have seen that there are many books titled:
Build Ecommerce website in php
Build shopping carts in php or asp.net
Is there any book which explains, from scratch, how to start building a website in Java using any framework or with servlets or JSP?
Desired topics:
Basic forms with logins and registration
Building catalogue system
Building shopping cart
Building newsletters system
Is there a way in Java to find the "Last Fired Time" from a Cron Expression.
E.g. If now = 25-Apr-2010 10pm, cron expression "0 15 10 ? * *" (quartz) should return me 25-Apr-2010 10:15am
I do not care if we use standard cron expressions (like Unix and Quartz) or less popular ones if they can fetch me the correct "Last Fired Time"
Learning just another language is not much work. However, getting familiar with all the supporting libraries is veeeery expensive and actually you cannot go too far without that.
Would you consider a worthy career investment to learn java once you already are an accepted professional of .NET or you would rather invest the same amount of energy to get deeper in the things you already know?
Does anyone know of a tool (besides Eclipse or any other IDE) that I can use to find unused imports in a Java source file?
I am looking for a command-line type of tool (to integrate in a larger script).
Thank you.
If I wanted a single word that meant "conforming to Java language conventions", what would that be? Python has the term "pythonic". Would it be "javaish"?
I am actually new to java programming and am finding it difficult to take integer input and storing it in variables...i would like it if someone could tell me how to do it or provide with an example like adding two numbers given by the user..
I'm trying to recompile a project I've been working on and I keep getting an error message when trying to load a property file:
The system cannot find the path specified.
I guess this has to do with the classpath. But I've added the path to the file in Properties- Java build path- Libraries (external class).
I also checked the .classpath file generated by eclipse, and the path is really there!
Why isn't Eclipse looking at the right path?
