Java Programming

Yes, it helps both the users and the maintainers of your class. Users are generally only interested the class interface (how to interact with the class), so by separating the implementation you do not distract the user with any unnecessary implementation details. Conversely, maintainers are more concerned with the implementation than the interface. By keeping the two separate, maintainers are much less likely to break any code that uses the class.

Sure you can, but it's never a good idea. You must never allow an exception to escape from a destructor. To do so would terminate the destructor prematurely, unwinding the call stack in search of an exception handler. This means that any remaining resources consumed by the instance, including its base classes, would be left in an invalid state with no possible way to recover those resources besides terminating the program. Any object that has the potential to throw an exception during its own destruction should always be treated with suspicion; it is a major design flaw.

The result of addition.
The answer of all your numbers added up.

100 metres seems to be the length of a spool of gardeners cotton Discuss:How_long_is_a_piece_of_string...we are not talking about jute twine here!So the maximum length of a piece of string would be 999.99mm!So the real answer to 'how long is a piece of string?' would be...anything between 0.01mm to 999.99mm.

step 1:

create menubar object and set it

step 2:

create menu objects with parameterized constructor

step 3:

add menus to menubar

32 bits or 4 bytes and an int is not an address, it is a primitive so it directly access the data without a reference.

The two types of variables are the CONSTANT and CONTROL.

In one sense, since EEPROM is memory, you don't program memory. You store things in memory, and the thing you are programming in this case would likely be a micro-processor or micro-controller that is on the same circuit as the EEPROM.

In theory, an EEPROM is just memory, so any language that would be able to produce machine language output for the CPU type connected to the EEPROM in any instance could be used.

In practice, many programs written to EEPROM would be for embedded systems. In this case, a lower level language like C could be used, or a higher level language that output C or the right kind of assembly.

A higher level language like C# or Java would likely not be used, as the overhead of the virtual machine might be considered to be too heavy for a micro-controller, or small micro-processor.

That being said, in practice, you could use anything. But it is likely you would have some libraries in C or C++ that you might want to use, so you would likely use a language that was compatible with any libraries you might use.

yah it's correct.

The error "Connection reset by peer" is a TCP error that occurs when a server sends your application a RST (i.e. reset) packet which terminates the TCP connection between you and the server.

You can retry manually and maybe the server will not reset you, but if you keep getting this there is not much you can do. It is the equivalent of slamming the phone back on the hook abruptly instead of politely saying goodby and gently hanging up.

There is only one comma, but it is not used in switch-case. Character literals are between apostrophes: 'x'

JAVA beans and coffee beans are two very different things . JAVA beans are used to generate getters and setters. while coffee beans are use to make coffee.

Cyclic inheritance is physically impossible. A base class cannot inherit from one of its own derivatives any more than you could inherit some generic trait from one of your own descendants. Inheritance is strictly a one-way street.

Its an interface.

The easiest way to implement a calculator is an RPN calculator (enter the numbers first, perform the operation last). You need a last-in-first-out stack (there's a "stack" class in C++, but you can also implement your own using an array or a linked list), and a set of functions that pop the last elements from the stack and push the result (e.g. Add() pops the last 2 values and pushes their addition).
You'll need the math.h library for scientific operations.

ColumnModel columnModel = table.getColumnModel();

for(Column: columnModel.getColumns()) {

Column column = <FIND COLUMN YOU NEED>;

}

columnModel.removeColumn(column);

By no means; you can access any random array element. If you have ever seen examples which process them in order, it is because of the following: when the order doesn't matter (for example, you want to calculate the sum of all the array elements), it is easiest to process them in order.

The Java Runtime Environment (JRE) converts the byte code to machine language.

the main purpose of the legislation was to stabilize the black workforce by compelling African Americans to work and by limiting their economic options … The laws aimed to replace the social controls of slavery, which had been legally swept away by the Emancipation Proclamation and the Thirteenth Amendment, and to reinstate the substance of the slave system without the legal form.

No. not directly.

The static constructor is called by .net framework, not by your code.

I always treat static constructor is the class initializer (not the instance one). The initialization routine is only called when the class definition being loaded.

When the derived class is loaded, since this class derived from the base, it makes to go up the chain (of the hierarchy) to call those static constuctors.

So, when a derived class is loaded, the static constructors of the hierarchy is called up. (any one of them had been loaded, the calling sequence stops).

You cannot call those static constructor directly, nor you can skip "not to execute" them.

Yes. There is no specific order in which the compiler expects methods to be present. As long as the method is inside the class it is perfectly fine.

Yes using the equals method.

Example:

Double a = new Double(Double.NaN);

Double b = new Double(Double.NaN);

if( a.equals(b) )

System.out.println("True");

else

System.out.println("False");

If you execute the above code snippet you will see "True" in the console. If you try the "==" operator to compare the 2 values a and b you will get only false
