Reserved Keywords in Java

Keywords are special tokens in the language which have reserved use in the language. Keywords may not be used as identifiers in Java.You cannot declare a field whose name is a keyword, for instance.


Below are all the Java language keywords:

abstract assert
boolean break
byte case
catch char
class const
continue default
do double
else enum
extends final
finally float
for goto
if implements
import instanceof
int interface
long native new package private protected public return short static strictfp super switch synchronized this throw throws transient try void volatile while

  • goto and const - are not used
  • enum - is present since Java 5.0
  • strictfp - is present since Java 1.2
  • assert - is present since Java 1.4
In addition, the identifiers null, true and false denote literal values and may not be used to create identifiers.

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...
