Yesterday in class we played a game called “Key Words”. Everyone had to name the key word and explain as best they could what it meant. There were about 15 of us, enough for more than three laps. Some dropped out in the first, some in the second. On a happier note, I was the last to drop out. Those. took second place, if you can give out places, in this game. So, try your hand, without the help of Google, of course, otherwise the point is lost, remembering them all without explanation. To check yourself, look under the cat. Currently, there are 50 (fifty!) keywords defined in the JAVA language. There used to be a little more, but the current JAVA specification specifies 50 words, which are listed below. I tried to break them into groups, I won’t explain each one, so most of it should be clear. Primitives
byte
short
int
long
char
float
double
boolean
Loops and branches
if
else
switch
case
default
while
do
break
continue
for
Exceptions
try
catch
finally
throw
throws
Scope
private
protected
public
Advertisement\Import
import
package
class
interface
extends
implements
static
final
void
abstract
native // signals that the method is implemented in platform-dependent code, often in C. For example, the hashcode method in Object has such a modifier.
Create\Return\Call
new
return
this
super
Multithreading
synchronized
volatile
Keywords that exist (reserved) but are not used in the language
const
goto
Keywords that are not included in any of the groups
instanceof
enum // enumeration
assert // data check
transient // applies to class fields and means that the field is not part of the persistent state of the class. Those. During serialization, this field will not be written. And, accordingly, during de-serialization it will not be restored from the byte stream.
strictfp // I’ve heard everything except this word before, but I had to hear this for the first time (no one could name it and the word const, by the way). By modifying a class, method, interface with the strictfp keyword, you ensure that floating point calculations will be performed as in older versions. This is done to ensure that the results of floating point operations are consistent across all platforms.
PS All these words in alphabetical order and with small explanations are here. That's all for now! Good luck to everyone and see you again!
