Please help me,

Question

I want to write a method, the input data is int array length and string numbers separated by commas. In the method, we separate and convert the numbers into an array, I can’t correctly enter data into the mathode or withdraw it from it, in any case, the method does not work. The code itself works great without the method. Data Entry Example

Answer 1

Your declaration of methods is wrong..
Method in method is not works..

Main() {
//...
// call method
//
}
createArray() {
...
}

This is Valid structure.

Put your createAreay method definition out of main method. Make it static.
and start from 0 to ', ' index in convert.
Add +1 to end index for remove method...

These changes will work to complete it..
