Java Assignment Operators / Chapter -9/Operator & Assignments

Java Assignment  Operators

In Java, there are three assignment operators.Assignment operator always follows Right To Left Associativity.

1. 
   

   Simple Assignment

   
   


2. 
   

   Chained Assignment

   
   


3. 
   

   Compound Assignment

   
   

 

1.Simple Assignment:-
We can perform simple assignment at the time of declaration.

example:-

int a=10;

2.Chained Assignment :-
We can't  perform simple assignment at the time of declaration.

example:-
int a,b,c,d;
a=b=c=d=20;
System.out.println(a+"....."+b+"....." +c+"....."+d)

output is

20.........20.........20.........20.........

BUT:
int a=b=c=d=20;
Compile Time Error: cannot find symbol
symbol: variable b
location: class name

3.Compound Assignment:-
When Assignment Operator is mixed with some other operator then the assignment is called as Compound Assignment.

example:-

int a=10;
a+=20;
System.out.println(a);
output is 20
Hint: a=a+20;

These are the following all possible combinations of Compound Assignment.

Note: In the Case of compound assignment operator internal type casting will be performed automatically.
