Java Operators
An overview of different operators used in Java
programming.

This presentation provides a detailed
examination of Java operators including
arithmetic, logical, relational, and more, along
with their usage and examples.
Introduction

Arithmetic operators are used to perform
mathematical operations on variables and
values. They include addition, subtraction,
multiplication, and division.
Definition and Usage

Common Operations
Key arithmetic operators include:
1. Addition (+)
2. Subtraction (-)
3. Multiplication (*)
4. Division (/)
5. Modulus (%) which finds the remainder.

For example:
1. int result = a + b; // Addition
2. int result = a - b; // Subtraction
3. int result = a * b; // Multiplication
4. int result = a / b; // Division
5. int result = a % b; // Modulus
Examples

Logical operators are used to combine
multiple boolean expressions. They include
AND (&&), OR (||), and NOT (!).
Definition and Purpose

Operation Types
1. AND (&&) - true if both operands are true.
2. OR (||) - true if at least one operand is true.
3. NOT (!) - reverses the boolean value of an
operand.

For example:
1. boolean result = (a > b) && (b < c);
2. boolean result = (a < b) || (b > c);
3. boolean result = !(a == b);
Examples

Definition and Application
Relational operators are used to compare two
values and return a boolean result (true or
false). They include equal to, not equal to,
greater than, less than, and so on.

Common relational operators include:
1. Equal to (==)
2. Not equal to (!=)
3. Greater than (>)
4. Less than (<)
5. Greater than or equal to (>=)
6. Less than or equal to (<=)
Comparison Functions

For example:
1. if (a == b) { ... }
2. if (a != b) { ... }
3. if (a > b) { ... }
4. if (a < b) { ... }
Examples

Assignment operators assign values to
variables. The main operator is the equal sign
(=).
Basic Assignment

Combined assignment operators modify the
value of a variable based on its current value:
1. +=, -=, *=, /=, %=.
Combined Operations

Examples
For example:
1. int result = a & b; // Bitwise AND
2. int result = a | b; // Bitwise OR
3. int result = a ^ b; // Bitwise XOR
4. int result = ~a; // Bitwise NOT
5. int result = a << 2; // Left shift
6. int result = a >> 2; // Right shift

Bitwise operators perform operations on
individual bits of integer values. They are used
for low-level programming, such as hardware
manipulation and encryption techniques.
Definition and Functions

1. Bitwise AND (&)
2. Bitwise OR (|)
3. Bitwise XOR (^)
4. Bitwise NOT (~)
5. Left Shift (<<)
6. Right Shift (>>).
Types of Bitwise Operations

Examples
For example:
1. int a = 5; // 0101 in binary
2. int b = 3; // 0011 in binary
3. Bitwise AND: a & b results in 1 (0001).
4. Bitwise OR: a | b results in 7 (0111).

Unary operators are operators that operate on a single operand
and include:
1. Unary plus (+)
2. Unary minus (-)
3. Increment (++)
4. Decrement (--).
Definition and Types

Increment (++) increases the value of a variable by
one.
Decrement (--) decreases the value of a variable by
one. They can be used in either prefix or postfix
notation.
Increment and Decrement

Examples
For example:
1. int a = 5;
2. int b = ++a; // a becomes 6
3. int c = a--; // c becomes 6, a becomes 5
again

Definition and Syntax
The conditional operator (?:) is a shortcut for
the if-else statement. It takes three operands
and evaluates one of the two expressions
based on a boolean condition.

Used for concise conditional expressions:
- Assigning a value based on a condition.
- Evaluating small conditional logic without
multiple lines of code.
Usage Scenarios

For example:
1. int max = (a > b) ? a : b;
2. String result = (isTrue) ? "Yes" : "No";
Examples

Definition and Purpose
The instanceof operator checks whether an
object is an instance of a specific class or
subclass. It returns true if the object is of the
specified type, otherwise false.

Used frequently in polymorphism to
determine the actual object type during
runtime. This helps avoid ClassCastException.
Type Checking

For example:
1. if (obj instanceof String) { ... }
2. if (a instanceof ParentClass) { ... }
Examples

In summary, understanding Java operators is
essential for effective programming. Each operator
serves a specific purpose, allowing developers to
perform various operations and make logical
evaluations efficiently.
