Java Programming

• It is easy to understand small sections of code in the modular programming.
• You can store the code across multiple files.
• Modular programming allows collaborative programming. Collaborative programming means more than one program work in one application at the same time.
• Duplication of code is not possible in modular programming. The programmers create a single procedure for code.
• The errors are localized to a subroutine or function and it is easy to find the errors.
• The code should be used in multiple applications in modular programming.
• The code should be simple and short in modular programming and it is less need to be written.

In order to covert SIS files to JAR files, you will need to download a safe and virus free SIS to JAR converter. This then compresses the files and allows you to open them in JAR format.

The term ministerial exception is the law that says that the government cannot regulate the religious institutions and their hiring processes. For example, if a Christian or Catholic school has rules about not hiring homosexuals the government cannot enforce discrimination laws.

The top level class in Java is class Object. Every other class inherits from Object and therefore Object is the top most in the class hierarchy.

If you extend a class from Object such as class Animal and further extend Animal with class Dog then the hierarchy is as follows:

Object

|

Animal

|

Dog

Code for this hierachy is as follows:

class Animal {

}

class Dog extends Animal {

}

We don't need to write class Animal extends Object because every class extends from Object so it does not need to be stated.

I think you're referring to the C/C++ concept of "dangling pointers." This is when you allocate some memory to a pointer, then deallocate that memory, but don't change the pointer. This causes any attempted use of the pointer to return an unused memory address.

There is no such concept in Java, since the programmer has little to no control over how memory is allocated or freed.

The closest thing I can think of is if you're using a class such as a Reader, in which you can close the object (Reader.close()) and then still have a reference to it. But in this case (and other similar cases) attempting to use the Reader further will result in an IOException being thrown.

import java.io.*;

class StringPalindrome

{

static void main()throws IOException

{

InputStreamReader isr=new InputStreamReader(System.in);

BufferedReader br= new BufferedReader(isr);

System.out.println("Enter a word");

String input=br.readLine();

int x= input.length();

char ans;

String fin="";

for(int y=x-1; y>=0; y--)

{

ans=input.charAt(y);

fin=fin+ans;

}

System.out.println("The reverse is " + fin);

if(fin.equalsIgnoreCase(input))

{

System.out.println("Palindrome");

}

else

{

System.out.println("Not a palindrome");

}

}

}

They provide the same level of abstraction and encapsulation, and similar inheritance.

The differences in inheritance: an abstract class forces you to have at least 1 subclass (otherwise this abstraction branch is useless, because you won't be able to create any instance), while a non-abstract class may have optional subclasses.

The number of numbers in the string; how long it is.

I don't see why it couldn't be.

Unless the Java class uses techniques or methods which are available to Java but not C++, then there is no reason that a C++ class couldn't be based on a Java class.

(1) America evolves after the American Revolution which gained Independence from the British (1775 to 1783)

(2) Purchase of Louisiana (1804)

(3) Texas Joins The Union (1845)

(4) American Civil War (1861-1865)

(5) The Indian Wars (ran for over 200 years ending in 1890)

(6) Statehood, the creation of most of the States that exist today (28 States Created)

Java applets are used to provide a self contained application or visually intensive experience to a user visiting a website. They are normally platform independent and as such the same Java applet can be delivered to users using Windows, Apple, or Linux.

In C, malloc is used to reserve a predetermined size of memory.

void * malloc ( size_t size );

calloc is used to reserve a chunk of memory large enough to store num elements, each of a predetermined size.

void * calloc ( size_t num, size_t size );

To create a char array of size 10 you can do it in one of two ways:

char* mChars = malloc( 10 * sizeof(char) );

char* cChars = calloc( 10, sizeof(char) );

There is no concept of malloc or calloc in Java.

In most languages, you can't have names with space, for functions, variables, etc. Assuming your function is called myFunction, the usual way to call it is:

myFunction()

This assumes the function requires no parameters. If the function does require parameters, the parameters will be included within parentheses.

Pure functions are those which do not modify the state of an object. Most often these are functions which take arguments and return a result.

Most mobile devices do not have the capability of handling the Java program.

Template functions provide the ability to write a single function that can accept different types of inputs and produce different types of output, while still using the same logic. For example, a template function can accept an int, long, or float and perform the same logic on any of the three types of parameters. The compiler ensures that the template function will make sense when compiled with a particular type. This was an early attempt at polymorphism (using the same code on different types of objects), and has since been superseded in newer languages using objects and inheritance.

Structured Analysis treats processes and data as separate components versus object-oriented analysis combines data and the process that act on the data into objects. http://www.dbar-innovations.com
