Java Programming

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 This was an early attempt at polymorphism (using the same code on different types of objects), and has since been superseded in newer languages using objects and inheritance.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

You cannot download a programming language, but you can download compilers. Check the attached link.

The polygon method is referred to as a graphical method because it visually represents data and relationships through geometric shapes, typically polygons. In this approach, data points are plotted on a graph, and lines or curves connect them to form a polygon, allowing for easier interpretation of trends, patterns, and correlations. This visual representation helps in analyzing complex data sets intuitively, making it accessible for decision-making and comparisons.

Java is not a necessity but there are some websites that will not work properly without it installed and activated. Java needs to be updated often or errors on certain pages will occur. Gaming sites require that it be installed and activated or the games will not operate.

I don't think this can be done. Why do you want to do it without operators, anyway? It is fairly simple to use them. - Of course, you could write a method that adds two numbers, but your method will internally still have to use operators.

import java.math.BigInteger;

public class MultiplyTest {

public static void main(String[] args) {

BigInteger bigInt1 = new BigInteger("5");

BigInteger bigInt2 = new BigInteger("8");

System.out.println(bigInt1.add(bigInt2));

}

}

Because it is one of the most important and widely used inheritance concepts in Java. In multi level inheritance a class directly inherits features from one class and indirectly inherits features form other classes that are in the inheritance hierarchy.

Java will take some time to learn. If you spend several hours a day you can learn the basics in a few weeks and do some "hello word" type programs.

If you're looking for more immediate results from a programming language you can look at Python or PHP.

No you cant, any compiler I've ever used wont allow this. It would not make any sense to do this anyway.

because the JVM directly accesses ur top class without instantiating it. Though for accessing the instance data members, the class must need to be instantiated.

That really depends on the programming language. In Java, it is sufficient to concatenate it with a String:

int myNumber = 5;

result = "" + myNumber;

Other languages may require a special function, or method, to convert from integer to string.

No. Java programs run in the Java Virtual Machine (JVM) - without it your computer won't know how to handle Java bytecode.

That will vary on the programming language used, but in general, it is a data type with a fixed number of decimal digits - usually four - which internally stores the number it represented as a whole number - for four digits, that would mean multiplying it by 10,000. It is commonly used to store currency values, but it can also be used for other type of data, when you are sure you won't need more than four decimals; its benefit is that additions and subtractions with this data type are exact - they don't suffer from rounding errors that appear when converting between decimal and binary, with other data types.
