Prompt Detail:
In Java, operators are symbols that perform various operations on variables and values. They allow you to manipulate data and perform calculations. Java supports a wide range of operators, which can be categorized into the following types:
Arithmetic Operators:
- Addition (+): Adds two operands.
- Subtraction (-): Subtracts the right operand from the left operand.
- Multiplication (*): Multiplies two operands.
- Division (/): Divides the left operand by the right operand.
- Modulus (%): Returns the remainder of the division of the left operand by the right operand.
Assignment Operators:
- Assignment (=): Assigns the value on the right to the variable on the left.
- Compound Assignment Operators (e.g., +=, -=, *=, /=, %=): Combines the arithmetic operation with assignment.
Increment and Decrement Operators:
- Increment (++) and Decrement (--): Used to increase or decrease the value of a variable by 1.
Relational Operators:
- Equality (==): Tests if two operands are equal.
- Inequality (!=): Tests if two operands are not equal.
- Greater than (>): Tests if the left operand is greater than the right operand.
- Less than (<): Tests if the left operand is less than the right operand.
- Greater than or equal to (>=): Tests if the left operand is greater than or equal to the right operand.
- Less than or equal to (<=): Tests if the left operand is less than or equal to the right operand.
Logical Operators:
- Logical AND (&&): Returns true if both operands are true.
- Logical OR (||): Returns true if at least one operand is true.
- Logical NOT (!): Reverses the logical state of the operand.
Bitwise Operators:
- Bitwise AND (&): Performs a bitwise AND operation between the two operands.
- Bitwise OR (|): Performs a bitwise OR operation between the two operands.
- Bitwise XOR (^): Performs a bitwise exclusive OR operation between the two operands.
- Bitwise NOT (~): Performs a bitwise negation of the operand.
- Left Shift (<<): Shifts the bits of the left operand to the left by the number of positions specified by the right operand.
- Right Shift (>>): Shifts the bits of the left operand to the right by the number of positions specified by the right operand.
- Unsigned Right Shift (>>>): Similar to the right shift, but fills the leftmost positions with zeroes instead of the sign bit.
Conditional Operator (Ternary Operator):
- The ternary operator (?:) is a shorthand version of an if-else statement and is used to evaluate a condition and return one of two values based on the result of the condition.
These operators play a crucial role in programming, enabling developers to perform various tasks and computations efficiently.
