Java operators are symbols used to perform arithmetic operations, comparison operations, logical operations and other operations. The following are commonly used operators in Java:

1. Arithmetic operators: are used to perform basic mathematical operations, including addition ( ), subtraction (-), multiplication (*), Divide (/) and find remainder (%).

2. Comparison operators: are used to compare the size relationship between two values, including greater than (>), less than (=), less than Equals (

3. Logical operators: are used to perform logical operations, including AND (&&), OR (||), NOT (!).

4. Bitwise operators: are used to operate on binary bits, including bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise NOT (~ ).

5. Assignment operator: is used to assign values ​​to variables, including assignment (=), increment (), and decrement (--).

6. Conditional operator (ternary operator): is used to select one of two values ​​​​based on conditions, the format is Condition? Value 1: Value 2.

7. Type conversion operator: is used to convert one data type to another data type.

8. String connection operator ( ): is used to connect two strings.

9. Auto-increment and auto-decrement operators: and --.

10. Relational operator: instanceof, used to determine whether an object is an instance of a class or an instance of a subclass of the class.

11. Null operators: == and !=, used to compare whether an object is null.

12. Type test operator: instanceof, used to determine whether an object is an instance of a specific type or its subclass.

13. Bit test operators: &, |, ^, ~, >, >>>.

14. Suffix increment and decrement operators: Use the or -- operator to increment or decrement the variable.

15. Prefix increment and decrement operators: Use the or -- operator to increment or decrement the variable in the expression.

16. Power operator: Use ^ or ** operator to calculate the power of a number.

17. Type cast: Use () and the type name to convert a value to the specified type.

These operators are used in Java programs to perform various calculations and control flow operations. It should be noted that different operators have different precedence and associativity, which determines the order in which they are evaluated in an expression. For example, arithmetic operators have higher precedence than comparison operators, while assignment operators have lower precedence than arithmetic operators. Therefore, in complex expressions, parentheses are needed to explicitly specify the order of evaluation.
