What are the functions of Java operators?

Java operators primarily serve the following purposes:

1. Arithmetic operators: used to perform basic mathematical operations, including addition (+), subtraction (-), multiplication (*), division (/), and modulus (%).
2. Assignment operators are used to assign values to variables, including simple assignment (=), plus-equal assignment (+=), minus-equal assignment (-=), times-equal assignment (*=), etc.
3. Relational operators are used to compare the relationship between two values, including equal to (==), not equal to (!=), greater than (>), less than (<), greater than or equal to (>=), and less than or equal to (<=).
4. Logical operators are used to perform logical operations, including AND (&&), OR (||), and NOT (!).
5. Bitwise operators are used to perform operations on binary numbers, including AND (&), OR (|), XOR (^), NOT (~), left shift (<<), and right shift (>>).
6. The conditional operator, also known as the ternary operator, is used to choose different values based on the truth or falsehood of a condition. The format is: conditional expression ? expression1 : expression2.
7. Increment and decrement operators: used to perform incrementing or decrementing operations on variables, including incrementing (++ ) and decrementing (– ).
8. The instanceof operator is used to determine if an object belongs to a specific class.
9. Priority operators are used to specify the order of precedence of operators, including parentheses () and the dot (.) operator.

These operators can be used to perform a variety of operations, allowing the program to achieve various functionalities.
