Order of Precedence and Associativity of Operators in Java

 Introduction

Operators are unique symbols in Java. These operators do specific tasks in Java. These operators follow an order of precedence and associativity in Java. In Java, operators with lower precedence are operated after the operators with higher precedence.

Operators

• Arithmetic Operators.
   
• Relational Operators
   
• Bitwise Operators
   
• Boolean Logical Operators

Bitwise Operators

• Bitwise unary NOT   ---   ~
   
• Bitwise AND   ---   &

• Shift Left   ---   <<
   
• Shift Right zero fill   ---   >>>
   
• Bitwise AND assignment   ---   &=
   
• Bitwise OR assignment   ---   \=
   
• Bitwise exclusive OR assignment   ---   ^=
   
• Shift Right assignment   ---   >>=
   
• Shift Left assignment   ---   <<=
   
• Shift Right zero fill assignment   ---   >>>=

Boolean Logical Operators

• Logical AND   ---   &
   
• Logical OR   ---   \
   
• Logical XOR   ---   ^
   
• Short circuit OR   ---   ||
   
• Short circuit AND   ---   &&
   
• Logical Unary NOT   ---   !
   
• AND assignment   ---   &=
   
• OR assignment   ---   \=
   
• XOR assignment   ---   ^=
   
• Equal to   ---   ==
   
• Not Equal to   ---   !=
   
• Ternary if-then-else   ---   ?:
