Features of Java

-

There is given many features of java. They are also known as java buzzwords.

Features of Java Programming Language are:

  • Simple
  • Secure
  • Portable
  • Object-oriented
  • Robust
  • Multithreaded
  • Architecture-neutral
  • Interpreted
  • High performance
  • Distributed
  • Dynamic

Simple :

  • Java is Easy to write and more readable and eye catching.
  • Java has a concise, cohesive set of features that makes it easy to learn and use.
  • Most of the concepts are drew from C++ thus making Java learning simpler.

Secure:

  • Java program cannot harm other system thus making it secure.
  • Java provides a secure means of creating Internet applications.
  • Java provides secure way to access web applications.

Portable:

  • Java programs can execute in any environment for which there is a Java run-time system.(JVM)
  • Java programs can be run on any platform (Linux,Window,Mac)
  • Java programs can be transferred over world wide web (e.g applets)

 Object-oriented:

  • Java programming is object-oriented programming language.
  • Like C++ java provides most of the object oriented features.
  • Java is pure OOP. Language. (while C++ is semi object oriented)

Robust:

Java encourages error-free programming by being strictly typed and performing run-time checks.

Multithreaded:

Java provides integrated support for multithreaded programming.

Architecture-neutral:

  • Java is not tied to a specific machine or operating system architecture.
  • Machine Independent i.e Java is independent of hardware .

Interpreted:

  • Java supports cross-platform code through the use of Java bytecode.
  • Bytecode can be interpreted on any platform by JVM.

High performance:

  • Bytecodes are highly optimized.
  • JVM can executed them much faster .

Distributed :

  • Java was designed with the distributed environment
  • Java can be transmit,run over internet.

Dynamic:

Java programs carry with them substantial amounts of run-time type information that is used to verify and resolve accesses to objects at run time.

Naming Conventions

-
Image
A naming convention is a rule to follow as you decide what to name your identifiers (e.g. class, package, variable, method, etc..). Different Java programmers can have different styles and approaches to the way they program. By using standard Java naming conventions they make their code easier to read for themselves and for other programmers. Cases in Java Naming Convention: Using the right letter case is the key to following a naming convention: Lowercase is where all the letters in a word are written without any capitalization (e.g., while, if, mypackage). Uppercase is where all the letters in a word are written in capitals. When there are more than two words in the name use underscores to separate them (e.g., MAX_HOURS, FIRST_DAY_OF_WEEK). CamelCase (also known as Upper CamelCase) is where each new word begins with a capital letter (e.g., CamelCase, CustomerAccount, PlayingCard). Mixed case (also known as Lower CamelCase) is the same as CamelCase except the fir...

Syntax: if(condition-1) {    //Statements which will be executed if condition-1 is true } else if (condition-2) {    //Statements which will be executed if condition-2 is true } . . . . else if (condition-n) {    //Statements which will be executed if condition-n is true } else {    //Statements which will be executed if none of the conditions in condition-1, condition2,…condition-n are true. }    //Statements which will be executed always As you can see in this if-else-if ladder, conditions are evaluated from top. First condition-1 will be evaluated and if this is true, the code inside the if block will be executed. If condition-1 is false, condition-2 will be evaluated. If condition-2 is true, the code inside that else if block will be executed. If condition-2 is false, condition-3 will be evaluated. This will go on like this. If none of the conditions are true, the code inside the else block wil...

Nested if..else Statement

-
You can combine multiple if / if-else /if-else-if ladders when a series of decisions are involved. So you can make sure that your program executes certain instructions when a series of conditions are met. Syntax: if(Boolean_expression 1) { //Executes when the Boolean expression 1 is true; } if(Boolean_expression 2) { //Executes when the Boolean expression 2 is true } //Statements which will be executed always      Example: public class Test {    public static void main(String args[])    {        int x = 30;        int y = 10;        if( x == 30 )        {            if( y == 10 )            {            System.out.prin...
