Separators in Java

Be it a programmer who is unaware of this concept but is indulging in every program. Separators help us defining the structure of a program. In Java, There are few characters used as separators. The most commonly used separator in java is a semicolon(;). Let us explore more with the help of an illustration with the “Hello World” program to put more emphasis on separators.

Illustration: Hello World

Observations drawn are as follows:

• In line 3, ‘{‘ is used to define starting of block class GFG
• In line 6, ‘{‘ is used to define starting of block main method
• In line 10, ‘;’ is used to terminate the sentence
• In line 11, ‘}’ is used to define the ending of the block main method
• In line 12, ‘}’ is used to define the ending of block class GFG

These separators are pictorially depicted below as follows: 

Symbol	Name	Purpose
( )	Parentheses	used to contain a list of parameters in method definition and invocation. also used for defining precedence in expressions in control statements and surrounding cast types
{ }	Braces	Used to define a block of code, for classes, methods and local scopes Used to contain the value of automatically initialised array
[ ]	Brackets	declares array types and also used when dereferencing array values
;	Semicolon	Terminates statements
,	Comma	Used to separates package names from sub-package and class names and also selects a field or method from an object
.	Period	separates consecutive identifiers in variable declarations also used to chains statements in the test, expression of a for loop
:	Colon	Used after labels
