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|
