What are Operators in Java?
Unlock the power of Java operators and elevate your programming. From arithmetic to bitwise, understanding how each operator works is key to writing efficient, clean code. Whether you're new to Java or a seasoned pro, this blog dives into the different types of operators and how to use them effectively. It is a versatile and platform-independent language and runs on any device that has a Java Virtual Machine(JVM), known for its reliability, easy use, and cross-platform capabilities. Java is extensively utilized in developing applications for Web, Mobiles, and Desktops. It operates based on the principle (WORA) “Write Once, Read Anywhere”.

Java is used by many professionals in areas like Web Development, Cloud Computing, Big Data Analytics, Internet of Things, Game Development, Testing, and Automation. Operators are building blocks of Java programming language that allow you to perform calculations, and comparisons between two or more operands and will display a result.
What are the different operators?
In Java, operators are special symbols used to perform various operations depending on the task. They enable you to calculate, make comparisons, and manipulate data between two or more operands. These operators are built into Java, allowing you to handle operations based on the given input efficiently. To learn more about this, check out Java Course in Marathahalli
Arithmetic Operators
Arithmetic Operators in Java perform basic mathematical operations with data types like int, float, double, etc. These include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%), which returns the remainder of a division. These operators are essential for performing calculations and manipulating numbers in Java programs. The list of arithmetic operators is as follows:
Addition: It calculates the sum of the two operands.
Example: int sum = 5 + 3; // sum = 8
Subtraction: It subtracts the second value from the first.
Example: int diff = 5 - 3; // diff = 2
Multiplication: It calculates the product of two operands
Example: int product = 5 * 3; // product = 15
Division: It divides the first operand by second and it results in int if both operands are int.
Example:int quotient = 6 / 3; // quotient = 2
Modulus: It returns the remainder of the division of the first operand by the second operand.
Example: int remainder = 5 % 3; // remainder = 2
Relational Operators
Relational operators in Java compare two values and return a boolean value as a result either true or false. These operators are essential for making decisions in code based on conditions.Various operations can be performed using relational operators.
Equal to(==): It evaluates to true if the two sides are equal.
Example: int a = 10, b = 5;
a==b; // Output: false
Not equal to(!=): It evaluates to true if the left-hand side is different from the right-hand side.
Example: int a = 10, b = 5;
a!=b; // Output: true
Greater than(>): It returns true if the value on the left is greater than the value on the right.
Example: int a = 10, b = 5;
a>b; // Output: true
Less than(<): It evaluates to true if the left-hand side is lesser than the right-hand side.
Example: int a = 10, b = 5;
a<b; // Output: false
Greater than or equal to(>=): It evaluates to true if the left-hand side is greater or equal to the right-hand side.
Example: int a = 10, b = 5;
a<=b; // Output: true
Lesser than or equal to(<=): It evaluates to true if the left-hand side is less or equal to the right-hand side.
.
Example: int a = 10, b = 5;
a<=b; // Output: false
Logical Operators
Logical Operators in Java are similar to digital gates in electronics. Various operations can be performed using logical operators.
Logical AND: It returns true when both the conditions are true.
Example: boolean x = true, y = false;
x && y; // Output: false
Logical OR: It returns true when at least one of the conditions is true.
Example: boolean x = true, y = false;
x || y; // Output: true
Logical NOT: It returns true when a condition is false.
Example: boolean x = true, y = false;
!x; // Output: false
Assignment Operators
Assignment Operators in Java are used to assign a value to a variable. By combining the assignment operator with other operators, a shorter form of the statement called a Compound Statement, can be constructed. For example, instead of a = a+70, we can write a += 70. Various operations can be performed using assignment operators.
Simple assignment(=): It assigns a value to a variable.
Example: int x = 10;
Add and assign (+=): It adds the left operand with the right operand and then assigns it to the variable on the left.
Example: a+=5; Output: a=a+5
Subtract and assign(-=): It subtracts the right operand from the left operand and then assigns it to the variable on the left.
Example: a-=5; Output: a=a-5
Multiply and assign(*=): It multiplies the left operand with the right operand and then assigns it to the variable on the left.
Example: a*=5; Output: a=a*5
Divide and assign(/=): It divides the left operand by the right operand and then assigns it to the variable on the left.
Example: a/=5; Output: a=a/5
Modulus and assign(%=): It assigns the modulo of the left operand to the right operand and then assigns it to the variable on the left.
Example: a%=5; Output: a=a%5
Increment and Decrement Operator
The Increment and Decrement Operators in Java allow you to adjust a variable's value by 1. The increment operator (++) increases the value by 1, while the decrement operator (--) decreases it by 1. These operators can be used in two forms: prefix (e.g., ++x) and postfix (e.g., x++), affecting the order of operations. These operators are commonly used in loops and counters to modify the value of a variable efficiently.
Bitwise Operators
Bitwise Operators in Java are used to manipulate every bit of data.They are utilized for updating and querying operations in Binary Indexed Trees.Various operations can be performed using bitwise operators.
Bitwise AND(&): It returns the value bit by bit AND of input values.
Example: b & a;
Bitwise OR(|): It returns the value bit by bit OR of input values.
Example: a | b;
Bitwise XOR operator(^): It returns a bit-by-bit XOR of input values.
Example: a ^ b;
Bitwise Complement Operator(~): This unary operator produces the one's complement of the input value by flipping all its bits.
Example: a ~ b;
Instanceof Operator
An instance of the operator in Java is used to check whether the object is an instance of a class, sub-class, or interface, also used for type checking.
Example: obj instance of ClassName;
Java provides a variety of predefined operators, each suited for different purposes in programming. These include arithmetic, assignment, logical, relational, ternary, bitwise, instanceof, increment & decrement. Java’s versatile operators enable developers to write clear, precise, and efficient code, adapting to different requirements and making it a powerful language for a wide range of applications.
