How to use the Scanner class to read two inputs separated by a Java space, and by two different variables?

I am trying to do something simple, I would like that, given two arguments separated by a space, read through stdin, each be stored in a different variable, for example:

 Scanner s1 = new Scanner(System.in)

 Scanner s2 = new Scanner(System.in)

 input1 = s1.nextLine();

 input2 = s2.nextLine();

 a = input1 

 b = input2

And the user writes in System.in, for example:

> Up Down

In the code I gave as example input1 and input2 are always reading the same things, I need one to read only the first argument and the other only the second argument.

Considering the example, how do I make the variable a receive only the string Up, and the variable b receive only the string Down?

    You don’t need to create two scanners if they read from the same place (in this case, from System.in). Just use one that’s enough

Just use one scanner and apply split(" ") to the String returned by him:

input = s1.nextLine();
String [] palavras = input.split(" ");
for (String palavra : palavras) {
    System.out.println(palavra);
}

String comando = palavras[0];
