byte:
A 8mpitos datatype length of a character.
case:
Use a command switch for implementing a code division (among many Alternatively) depending on the value of a variable.
catch:
Used to trap errors within a section try.
char:
A 16mpitos datatype length of a character.
class:
A hierarchical collection of data and methods which act on these data.
continue:
Skips all remaining commands a loop and continues the execution of doika the next iteration of the loop.
default:
Execute commands on a switch section when all cases (case) of this section switch proved false (false).
do:
Used with the reserved word while for executing a loop.
double:
A number of double precision floating point.
else:
Used within a command structure if the execution of a command section when the treaty is controlled by the command if proven false (false).
extends:
When you extend a class (extends) to another class inherits the properties of this class.
false:
A stable, contrary to true.
final:
When a class is declared as final (final) can not be passed properties earth.The a method declared as final, can not be parakamfei.Telos the declaration of a variable as final renders constant that can not be changed.
finally:
Makes compulsory the implementation of a code division in part try ... catch.
float:
A simple float (single) precision.
for:
A loop to return the original value, checking the Treaty, and a command that runs on each repetition.
if:
Checks a condition and if true (true), performing a code snippet.
implements:
Specifies a class to use an interface.
import:
do the Java classes available in the current system through a short name.
instanceof:
Checks whether a variable is the presence of a particular class or implements (implements) a specific interface.
int:
an integer.
interface:
Contains methods grouped glanced between classes implement (implements) interfaces (interface) so that they can use their methods.
long:
A very large integer.
native:
Declares a function as an external java.H method implemented in a language that depends on the particular computer system, such as C or C + +.
new:
Creates a new presence of an object, allocating memory and giving initial values to variables.
null:
All attendance of classes originally the value null (which is constant) to give them a value to a new command or to assign it an existing order.
package:
A group of classes that are "packaged" together.
private:
Makes an object visible only in the order in which it was designed.
protected:
makes an object visible only for the package (package0 in which it was designed.
public:
Makes an object visible everywhere visible the class or package in which it was designed.
return:
Returns control (and sometimes variables) by a method in the method requested.
short:
A small integer.
static:
Static methods have only a one attended every class, called by the name of the class.
strictfp:
Used to ensure that some simple representations (float) or double (double) precision symmirfonontai with specific rules adopted by the Committee IEEE.Kata probably will not have to ever use it if necessary but do not forget to take a look at the documentation, the site java.sun.com.
super:
Allows access to ancestral properties of objects that were overridden by descendants properties of objects.
switch:
Performing a portion todika (among many) depending on the value of a variable.
synchrinized:
Only one thread of the method may be performed each time.
this:
Refers to the current presence of a class.
throw:
Requires the appearance of an error.
throws:
Suggests that this method may cause the exception or the error is defined.
transient:
A "rough" for a variable order, which was not stored with the class or "cloned" in other instances of the class.
true:
A stable, contrary to the false.
try:
Provides a code segment for the "capture" errors that "arrest" takes first command and then catch several pieces of code.
void:
States that this method will not return any value in the method requested.
volatile:
This variable can be changed at any time, so we should not allow optimization of the code.
while:
Used in conjunction with a command to do perform a loop.

Thats all from me.
I make this topic for two reasons
1)to learn them alone,without read from book(I tried to learn by heart, I did some others do not.)
2)to help some peoplse who is new in Java.

Credits: Java 2 book
( as i said I tried to learn by heart, I did some others do not.)
I think this must be sticky,its pretty usefull and helpful.
