Assignment operator is the most common operator almost used with all programming languages.

Java Operators

1. Simple Assignment Operator
   Assignment operator is the most common operator almost used with all programming languages.
       
2. Arithmetic Operators
   Arithmetic Operators are used to perform some mathematical operations like addition, subtraction, multiplication, division, and modulo (or remainder).
     
3. Unary Operators
   The unary operators requires only one operand to perform different kind of operations such as increasing/decreasing a value, negating an expression, or inverting a boolean value.
     
4. Equality and Relational Operators
   Whenever we need to compare the results of two expressions or operands in a program then the equality and relational operators are used to know whether an operand is equal, not equal, greater than, less than to another operand.
      
5. Conditional (Logical) Operators
   Conditional operators return a true or a false value based on the state of the variables i.e. the operations using conditional operators are performed between the two boolean expressions. 
     
6. Bitwise and Bit Shift Operators
   In Java the bitwise and bit shift operators are used to manipulate the contents of variables at a bit level according to binary format.
     
7. Type Operators
   Java provides a run-time operator instanceof to compare a class and an instance of that class. This operator " instanceof" compares an object to a specified class type
     
8. Operator Precedence
   In Java, Operator Precedence is an evaluation order in which the operators within an expression are evaluated on the priority bases.
