What are operators in java?
An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. Java has almost same operators like C / C++.
There are three types of operators in java according to number of working operands :-
Operators
Unary Operator
Ex.
++
-- etc.
Binary Operator
Ex.
+ -
== etc.
Ternary Operator
Ex.
Condition ? Statement 1 : Statement 2
Examples of operator precedencies in java
Ex.
Total = 10+50*40/2-2
= 10+2000/2-2
= 10+1000-2
= 1010-2
= 1008

Total = 5*(6+16)/2
= 5*22/2
= 110/2
= 55

Total = 5*6+16/2
= 30+16/2
= 30+8
= 38
Rules for associativity of operators in java
Rule 1: Except the assignment and relational all binary operators have left to right associativity.
Ex.
X = 10 * 20 / 2 % 4
= ((200 / 2) % 4)
= 100 % 4
= 0
Rule 2 : Except the postfix increment and decrement operator all the operators have right to left associativity.
Ex. a=b=c=d=10
a=b=c=d
a=b=c … then finally a=10
