User input String in Java !!!

Question

Can't I get string input using this method..?

//scan is my Scanner name

String sentence = scan.nextLine ();

I tried it but my program didn't asked me to give any input... What is problem with this one.. ? Can anyone tell me in details please :(

Answer 1

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?

Answer 2

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

Answer 3

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

Answer 4

@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)

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

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.
