Can you input string and number in one input in java?

Question

I'm making a caeser cipher program with encrypt and decrypt!

Answer 1

Codinger 🖥️🇲🇰 my older post means input like this: "hello123"

As ~ swim ~ posted you can also keep it separate:

Scanner scan = new Scanner(System.in);
int number = scan.nextInt();
String text = scan.nextLine();

Thanks,Denise!

Answer 4

You have to use a String.
Scanner scan = new Scanner(System.in);
String input = scan.nextLine() or scan.next()

Then you can work with the characters of your String. A char can be everything: letter, number, special character.

It depends on what you want to do. If you want to manipulate the chars, you should use an char array.
String str = "hello";
char[] c = str.toCharArray();

If you don't manipulate the chars (e.g. if you count numbers or vowels) then you can use a loop.
To get a char of a String -> .charAt(int index)

Here is an simple example:

String str = "hello";

for(int i = 0; i < str.length(); i++){
System.out.println(str.charAt(i));
}

Answer 6

If you want to accept both a string and a number input then string is the best to use, just something like this
Scanner s = new Scanner(System.in);
String input = s.nextLine()

Answer 7

So basically, turn a string into an array of characters? Am I getting this right Denise Roßberg 😁
