Originally, next() and nextInt() are spaced apart,
I know that the nextLine() stops receiving space in the enter so that it can receive space,
Write down the address like above and press enter.
The previous ones (name to address) are printed out...
What's wrong with this?
How do I get it to the end (even single) and print it out at once?
Instead of making a variable and printing it once at the end...
java scanner nextline
Are you curious about the reason why this is happening?
Calling a method of the next class of Scanner receives user input.
Count how many methods start with the next in the code written by the questioner. You're going to get that number of inputs.
And the reason why they're printed is also simple.
This is because the code written by the questioner is printing the results that you entered each time on the screen.
"Not how to make a variable and print it out at once at the end." <- Didn't you write the code above to do this?
Do you want to get the results after receiving the input of name, age, weight, city address, and single status by comma? (You have to be good at asking questions. Don't forget that good answers come from good questions.)
If what I expected is right...You can get one line with the nextLine and get it as a token by dividing it with commas through the split method of the String class.

Stream<String> dataStream = Arrays.stream(datas);
dataStream.forEach(i -> System.out.println(i));

Input: aaaa, 10,100, 50.0, Seoul, Korea Seoul, true
Output:
