? Java Method Return Types

? Quick Overview

In Java, a method can return a value to the caller. The return type defines what kind of value a method sends back after execution. Return types make methods reusable, predictable, and type-safe.

? Key Concepts

Every Java method must declare a return type
void means the method returns nothing
Primitive types and objects can be returned
The return statement ends method execution

? Syntax / Theory

The return type is written before the method name. The returned value must match the declared type.

// Method returning an integer value
int add(int a, int b) {
return a + b;
}

? Code Examples

? View Code Example
