? Java Operator Precedence

? Quick Overview

Operator precedence in Java determines the order in which operators are evaluated in an expression. Operators with higher precedence are evaluated before operators with lower precedence unless parentheses are used.

? Key Concepts

Precedence controls evaluation order
Associativity decides direction when precedence is equal
Parentheses override default precedence
Understanding precedence avoids logical bugs

? Syntax / Theory

Java evaluates expressions using predefined precedence rules. For example, multiplication has higher precedence than addition.

() – Highest precedence
*, /, % – Multiplicative
+, - – Additive
= – Assignment (lowest)

? Code Example

? View Code Example

// Demonstrating operator precedence in Java
public class OperatorPrecedence {
public static void main(String[] args) {
int result = 10 + 5 * 2;
System.out.println(result);
}
}

? Live Output / Explanation

Output

The output will be 20 because multiplication (5 * 2) is evaluated before addition.

✅ Tips & Best Practices

Use parentheses for clarity
Do not rely on memorizing all precedence rules
Write readable expressions
