Java Methods

Java Methods (Functions)

A method in Java is a block of code that performs a specific task. Methods help reuse code, improve readability, and make programs modular.

1. Syntax of a Method

• modifier → public, private, static, etc.

• returnType → data type returned (void if nothing is returned)

• methodName → name of the method

• parameters → optional input values

2. Example 1: Method without Parameters and Return Value

📌 Output:

3. Example 2: Method with Parameters

4. Example 3: Method with Return Value

📌 Output:

5. Example 4: Method Overloading

Java allows multiple methods with the same name but different parameters (overloading).

6. Example 5: Calling One Method from Another

📌 Output:

🧠 Key Points

• Methods improve code modularity and reusability.

• A method can:

  • Take parameters (inputs)

  • Return a value

  • Be called from other methods

• Use void if the method does not return anything.

• Overloading allows methods with the same name but different parameters.
