Java Programming

I assume that your scanner is not scanning a string already, so if you are scanning an int then you can do: for the example you scanner variable is x .... x.intparseString();

You can use a JLabel to put text on a JPanel. You put a string in the JLabel and put the JLabel on a JPanel

There are a lot of source doe analysis tools including NET, Multi-language, ABAP, Opa, Java and ActionScript. Most code analysis tools are used to increase the performance of a programs and for checking the code of a program.

A Vector can store any objects, so yes.

int i, sum;

/* example using while */

sum = 0;

i = 1;

while (i <= 100) {

sum += i;

++i;

}

/* example using for */

sum = 0;

for (i = 1; i <= 100; ++i) sum += i;

Some examples are SQLServer , MySQL, Orcle

Both are aggregates of elements of the same type. The main difference is that an array allocates elements contiguously thus there is no need to maintain links between the elements; each can be addressed by its offset from the start of the array. A structure, however, allocates elements non-contiguously, and must maintain links (pointers or references) within the elements in order to navigate from one element to the next.

It all comes down to what you use it for. C++ can be faster and tends to use less RAM as it accesses hardware directly (but is not always and Java has caught up quite a bit over they years when it comes to speed and is currently working on its memory usage). On the other hand, Java can be made to run on any platform (windows, Linux, Mac, BSD, ...) that has a JVM, which means that the code does not require any modification, making production and maintanenance faster and cheaper. Also, Java is a lot more unlikely to suffer from memory leaks as it was created with the shortcomings of C++ in mind. It will often clean up for you if you make a mess while C++ will stand by pretending that its nose is bleeding. Then you get to keep the pieces. That being said, C++ is a better choice for multimedia, which has always been badly neglected on the Java side. However, C++ has only a fraction of the many frameworks and tools that have been written to facilitate writing web applications in Java. And so on. As I said, it all comes down to what you have in mind.

A Deadlock is a situation of indefinite waiting where the system is stuck at a particular point and would do nothing useful.

For example Method A is waiting for B's input while B is waiting for C's input and C in turn is waiting for A's input. Here all the 3 methods would continue to wait because they are waiting on one another and the system is stuck.

A deadlock usually occurs while using threads. Threads can lock objects on which they are processing and when multiple threads are waiting for the same object a Dead lock may occur.

The use of the synchronize keyword can be used to avoid such deadlock situations.

There are benefits in almost every career you choose. Ultimately, it depends on your interest. If you like programming, then Software Engineering is the perfect choice for you. Plus, the average wage of a software engineer is quite high and they are currently in high demand throughout US and Canada.

You cannot unless you wrote some kind of translator. The only exception is NET which allows to run codes written in different languages using the same coding environment.

It means that the function is old (and often poorly designed) so should not be used anymore. It is kept there for backwards compatibility.

this questions isn't specified enough to be answered

Inheritance is simply when you get properties and methods from a superclass, whereas instantiation is actually allocating an object in memory based on your class.

On user manual it is written that it supports JAVA files but a lot of complaints by customers shows that JAVA application as a whole is not supported by Corby Pro.

A database is about storing data, not about creating forms. You would create the forms in some programming language - NOT something directly related to the database server - than have your forms, or rather your program in general, connect to the database.

SUN stands for Stanford University Network

An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable.

Instance variables are accessed as follows:

objname.variableName;

Class variables are accessed as follows:

ClassName.variableName;

JFC stands for Java Foundation Classes. They are a set of GUI components and services which simplify the development and deployment of commercial-quality desktop and internet/intranet applications.

JAVA is a oop programming language which is platfrom independent.
Previous name of java is ook.
It is derived by Sun Microsystem in USA.
From some offical conflict it converted to java.
Sun engineers everyday go to a coffeshop which is near their office .During taking coffe
they decided to change its name from 'ook'.
Suddenly they think that its hot coffe.
So the actual java name in USA is 'hot cofee'

No if there was then java wouldn't have over 4 billion down loads

a class can control what information or data can be accessible by other classes

access modifiers sets usability of the methods defined in the class by other classes in either the same package or the other,

this is how acces modifiers encapsulates the variables or the methods from being used .

like there are 3 access modifiers--

1.protected-can be used in the same class or class which has inherited it .

2.default-can be used in the same package,but no acces to other classes.

3.public-can be used by classes in different package.

To have a string split in Java means that a string array, containing substrings (can be delimited by elements of a specified string or Unicode character array), is returned.
