What are the number operations in Java?
I'll be happy to help you with that.
In Java, there are several number operations that can be performed on integers and floating-point numbers (doubles). Here's a comprehensive list of those operations:
Arithmetic Operations
Addition (++): Used to add two numbers together. The+ operator is used for both integer and double addition.
Example: int a = 5; int b = 3; int sum = a + b;
- operator is used for both integer and double subtraction.
Example: double a = 10.0; double b = 2.0; double difference = a - b;
* operator is used for both integer and double multiplication.
Example: int a = 4; int b = 5; int product = a * b;
/ operator) or remainder-wise (using the % operator).
Example: double a = 10.0; double b = 2.0; double quotient = a / b; int remainder = a % b;
Example: int a = 17; int b = 5; int remainder = a % b;
Example: int a = 5; a++; // a becomes 6 and int b = 3; b--; // b becomes 2
Comparison Operations
Equality (==): Used to check if two numbers are equal.Example: double a = 10.0; double b = 10.0; boolean isEqual = a == b;
Example: double a = 10.0; double b = 5.0; boolean isNotEqual = a != b;
Example: double a = 5.0; double b = 10.0; boolean isLessThan = a < b;
Example: double a = 15.0; double b = 5.0; boolean isGreaterThan = a > b;
Example: double a = 10.0; double b = 10.0; boolean isLessThanOrEqualTo = a <= b;
Example: double a = 15.0; double b = 10.0; boolean isGreaterThanOrEqual = a >= b;
These are the basic number operations in Java, and you can use them to perform various arithmetic calculations and comparisons with numbers.

According to various Java programming language resources, including official documentation and online tutorials, there are numerous operators available in the Java programming language. In this response, I'll provide an exhaustive list of Java operators, categorized into arithmetic, comparison, logical, bitwise, assignment, and other categories.
Arithmetic Operators:
+ (Addition) - performs addition between two operands - (Subtraction) - subtracts the second operand from the first * (Multiplication) - multiplies the operands together / (Division) - divides the first operand by the second % (Modulus or remainder) - returns the remainder of dividing the first operand by the second ++ and -- (Increment and Decrement) - increment or decrement a variable
Comparison Operators:
== (Equality) - checks if two operands are equal != (Inequality) - checks if two operands are not equal < (Less than) - checks if the first operand is less than the second > (Greater than) - checks if the first operand is greater than the second <= (Less than or Equal to) - checks if the first operand is less than or equal to the second >= (Greater than or Equal to) - checks if the first operand is greater than or equal to the second
Logical Operators:
&& (And) - checks if both operands are true and returns true if they are || (Or) - checks if either of two operands is true and returns true if so ! (Not) - negates an operand, returning the opposite boolean value
Bitwise Operators:
& (And) - performs a bitwise AND operation between two operands | (Or) - performs a bitwise OR operation between two operands ^ (Xor) - performs a bitwise XOR operation between two operands ~ (Not) - negates an operand, returning the opposite binary value
Assignment Operators:
= (Assignment) - assigns the right operand to the left += - adds the right operand to the left and assigns the result -= - subtracts the right operand from the left and assigns the result *= - multiplies the right operand with the left and assigns the result /= - divides the left by the right operand and assigns the result %= - calculates the remainder of dividing the left by the right operand and assigns it <<= and >>= - shift bits to the left or right using unsigned arithmetic
Other Operators:
instanceof (Instance Of) - checks if an object is an instance of a given class new (New) - creates a new object with the specified constructor arguments () (Parentheses) - used to group operators and expressions or provide clarity
In conclusion, there are numerous operators available in Java, each serving its unique purpose in programming logic. Understanding these operators is crucial for effective Java programming.
