Operators are fundamental to any programming language, and in Java, they allow us to perform computations, compare values, and manipulate bits. Understanding the different categories of operators is crucial for writing expressive and efficient code.
Whether you're calculating results, checking conditions, or performing low-level operations, the right use of operators ensures logic is both clean and powerful.
Java provides several types of operators that help you perform various operations. These include:
+, -, *, /, %&& (AND), || (OR), ! (NOT)==, !=, <, >, <=, >=&, |, ^, ~, <<, >>=, +=, -=, *=, /=, etc.These operators enable developers to build complex logic, perform calculations, control flow, and manipulate data at the binary level.
Understand all types of operators with examples and use cases.
public class OperatorExample {
public static void main(String[] args) {
int a = 10, b = 20;
// Arithmetic
System.out.println("Addition: " + (a + b));
System.out.println("Modulus: " + (b % a));
// Logical
boolean result = (a < b) && (b > 15);
System.out.println("Logical AND: " + result);
}
}
public class BitwiseExample {
public static void main(String[] args) {
int x = 5; // 0101
int y = 3; // 0011
System.out.println("Bitwise AND: " + (x & y)); // 0001 => 1
System.out.println("Bitwise OR: " + (x | y)); // 0111 => 7
System.out.println("Bitwise XOR: " + (x ^ y)); // 0110 => 6
}
}
Bitwise operators are extensively used in systems programming and device communication.
Arithmetic and logical operators are used for movement, scoring, and AI logic.
Logical operators help implement complex filtering conditions in database queries.
Logical AND (&&) operates on boolean expressions and supports short-circuiting. Bitwise AND (&) works on individual bits and does not short-circuit.
Bitwise operators are used in low-level programming, such as device drivers, cryptography, and performance-critical calculations.
It is 6. XOR compares each bit: 0101 ^ 0011 = 0110, which equals 6 in decimal.
