Java Method Return Types

Java Method Return Types

The return type of a method specifies what type of value the method will return to the caller. If a method does not return a value, we use void.

1. Syntax

• returnType → data type of the value returned (int, double, String, etc.)

• return statement → used to send a value back

2. Example 1: Method with int Return Type

📌 Output:

3. Example 2: Method with double Return Type

📌 Output:

4. Example 3: Method with String Return Type

📌 Output:

5. Example 4: Method with void Return Type

📌 Output:

❗ Note: void methods do not return a value, so no return statement with value is allowed.

6. Example 5: Using Method Return in Another Method

📌 Output:

🧠 Key Points

• The return type defines what type of value a method gives back.

• Use void if nothing is returned.

• A method can call another method and use its return value.

• Always match the return type with the value being returned.
