Java Programming

No. Java source code and C source code may look similar (since Java is based on C++, which is based on C), but the languages themselves are very different.

Yeah both are totally different language based on different paradigm JAVA is Object-Oriented while C is procedural.C breaks down to functions while JAVA breaks down to Objects. C is more procedure-oriented while JAVA is data-oriented.C is a low-level language while JAVA is a high-level language.Java is an Interpreted language while C is a compiled language.

arithmatic operator +,-,*,/,%

assigment oprator ==

logical operator &,|,^,&&,,!

bitwise opertor &,|,^

left shift <<

right shift >>

left shift zero fill <<

assignment operator +=,-=,*=,/=

there are certain rules to make up a relational data base management system, oracle follows it and so its an rdbms

public static void main(String[] args) {

int a = 5;

int b = 10;

int c;

c = a + b; // addition

c = a - b; // subtraction

c = a * b; // multiplication

c = a / b; // division

}

C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick.

For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.

It is possible to use arrays when employing java programming language. There are many different series of programming choice that can be employed with various end results.

You need to to know some basic math to live. right? Likewise you need to know some basic math to start computer programming....beginners start out by learning to do programs like solving a quadratic equation....if you are not thorough with algebra, u can't do it. The way you think is more important.....rather than being good in math, computer programmers are required to think the way math people think - vey very very logically.

Desoola Anil Kumar, Java Faculty: There are 5 types of Inheritance. 1.Single inheritance, 2.Multiple inheritance, 3.Multilevel Inheritance, 4. Hirarichal inheritance and 5. Hybrid inheritance. Java supports multi level inheritance and hirarichal inheritance.

There is no catch block that names either the class of exception that has been thrown or a class of exception that is a parent class of the one that has been thrown, then the exception is considered to be unhandled, in such condition the execution leaves the method directly as if no try has been executed

#include<stdio.h>

main()

{

int i,words,spaces;

char a[30];

printf("enter the string") ;

scanf("%s",a);

for(i=0;a[0]!="\0";i++)

{

if (a[i]=' ')

spaces++;

}

printf("the no. of spaces in the string is %d",spaces);

printf("the number of words in the string is %d",spaces+1);

}

Display function in de queue

void display()

{

int i;

if((front == -1) (front==rear+1))

printf("\n\nQueue is empty.\n");

else

{

printf("\n\n");

for(i=front; i<=rear; i++)

printf("\t%d",queue[i]);

}

}

4.(Displaying matrix of 0s and 1s ) write a method that displays by n by n matrix using the following header : Public static void printMatrix(int n) Each element is o or 1,which is generated randomely. Write a test program that prints a 3 by 3 matrix that may look like this: 010 000 111 4.(Displaying matrix of 0s and 1s ) write a method that displays by n by n matrix using the following header : Public static void printMatrix(int n) Each element is o or 1,which is generated randomely.

{

public static void main (String args[])

{

System.out.pritnln("My first Program in Java ");

}

}

Simple Java Programe

Write the above program in Ms dos's edit or Notepad of Windows save it with "firstprog.java" run the commands given below in command prompt of Ms Dos to get the output Remamber Java is case sensative so mentain capital and small letter.

1. javac firstprog.java

2. java firstprog

An abstract interface is an interface which has a one-to-many relation - providing multiple paths from a single location to multiple locations.

The char type store only one symbol of data (letter, digit, space, tab and so on). The string type is able to keep virtually data of any length. Also string type is based on arrays and uses reference type working with memory.

The Java executable comes with a showversion flag, so typing:

java -showversion

Will display something like:

java version "1.6.0_16"

Java(TM) SE Runtime Environment (build 1.6.0_16-b01)

Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

Note: This seems to be bugged on my machine. After printing out the above information, it also prints out the rest of the command line switches. If this happens to you, you may have to scroll up to see the important information.

One possible way (although much less efficient than using the operators directly) is by using BigInteger:

int a = 5, b = 7;

int sum = BigInteger.valueOf(a).add(BigInteger.valueOf(b)).intValue();

However, BigInteger.add() might use arithmetic operators in its own calculations; they are simply hidden from the programmer's view.

Thread can be created in two ways either by extending Thread or implementing runnable interface

Examples:

public class A extends Thread { } public class A implements Runnable { } By using both the methods we can create a Java Thread. The disadvantage of extending the Thread class is that, you cannot extend the features of any other class. If we extend the Thread class we cannot extend any other class whose features we may require in this class.

So it is usually advisable to implement the Runnable Interface so that we can extend the required features and at the same time use the Thread functionality.

class constructor is a function which has the same name as the class name and has no return type.

primitive data types are the fundamental data types which are independent.

eg:int,char,float etc..............
