1. Did you define your scan variable like this? Scanner scan = new Scanner (System.in); 2. Does your code throw an error? If so, what is the error message?

Could you publish your code at the playground and add a link to it here?

It's not reserved I see, that's my fault. The Sololearn IDE usually indicates reserved keywords in blue but I see now it only made it blue because it started with a capital letter. My apologies, I'll subtract my comment

@Mazharual here's a workable version of your code. When you run it and it requests input then separate your inputs with a space to enter multiple inputs (e.g 1.0 2.0 Hello) https://code.sololearn.com/c09ITW62EVgm/?ref=app

I just made your variables lowercase and commented out your package at the top of your code.

It was confusing for me too @Mazharul but I see now that nothing was really wrong with your variable names. The only problem your code had was that package you included. Why I got confused was because the variable names were in blue.

No, you use the package keyword to make a package of the code you're creating and then save it as a java file. Then in your main code you can import that package with the import keyword. Example (Java): import java.util.* //imports all classes of the util package. //Show when you must not use the package keyword with your main code

I read that you shouldn't use the same scanner for both Strings and numbers. I don't know that that's the problem, but I would try a second scanner for strings

Hi Mazaharul, both are used to read string alone. if u want to read int then use nextInt() ,nextFloat() for float and nextDouble() for double.
