Operators in Java
An operator is a symbol that tells the computer to perform certain mathematical or logical manipulations. Operators are used in programs to manipulate data and variables. Java supports a rich set of operators.
Java operators can be classified into 8 categories are given as below :
1. Arithmetic Operators: Arithmetic Operators are used to constructing mathematical expressions as in algebra. Java provides all the basic arithmetic operators.
2. Relational Operators: When we compare two quantities and depending on their relation, then we used some relational symbol that is called Relational Operators.
|<=||less than or equal to|
|>=||greater than or equal to|
|!=||not equal to|
3. Logical Operators: An expression that combines two or more relational expressions is called Logical Operators or Compound Operators.
4. Assignment Operators: Assignment Operators are used to assigning the value of an expression to a variable.
5. Increment and decrement operators : Java has two useful operators and these are the Increment and decrement operators.
+ + and – –
6. Conditional Operators: The character pair ?: is a ternary operator, it is used to construct conditional expressions that are called Conditional Operators.
7. Special Operators : Java supports some special operators such as instanceof opeartor and member of selection operator or dot operator (.) .
8. Bitwise Operators: Java has a distinction of supporting special operators that are known as Bitwise Operators. It is used to manipulate data at values of bit level and also used for testing the bits or shifting them to the right or left. Bitwise Operators may not be applied to float or double data types.
|^||bitwise exclusive OR|
|>>>||Shift right with zero fill|
