I have a question about a function of return in Java
class MethodDemo6 {
public static String numbering(int init, int limit) {
int i = init;
String output = "";
while (i < limit) {
output += i;
i++;
}
return output;
}
public static void main(String args) {
String result = numbering(1, 5);
System.out.println(result);
}
The part that I have been wondering is, the code 'returned' output.
After that, when the main part starts, it says String result = numbering(1, 5);
Instead of String output = numbering(1, 5);
It works, But I still cannot understand the mechanism.
Are result and output the same thing ?
Or are both like reserved words?
java return output result

The output named variable from inside the method is only visible inside the method (it is called a "local" variable).
This means that it is used only inside that block of code for computation. The return statement from the final line of the method brings the result outside of it, so when you run String result = numbering(1, 5);, the result variable will have only the resulted information from the method.

Thanks for the explanation, So, if I understood correctly, from this part 'String result = numbering(1, 5);', numbering(1, 5) directly indicates output. am I right ?

The result variable (which is of String data type, meaning it can hold a sequence of characters as information) is assigned with the output from the method named numbering with parameters 1 and 5. In short, result has the output.

The variable output of type String is local to the method numbering.
On the other hand, this method returns a String which is stored in the variable named result within your main method.

When calling a function, if the function returns anything the value is returned to the caller.
Your function numbering is of type String because it’s signature is written as
public static ‘String’ numbering (int...)
This means it returns a String to the caller, which in your case is result and the String that it returns is assigned to the variable output.
