如何从单个输入中获取两个字符串（单词之间用空格分隔）

Question

I am trying to create two strings from a single input.

So if the user inputs "John Doe" I want to have two strings J and D where J=John and D=Doe.

I tried using the scanner.nextLine() method but that won't let me create two strings from the single input.

So essentially I want to create another string whenever the user inputs a space between words.

If anyone can clear that up for me that would be wonderful! I have just started studying computer science so this is all new to me.

To get two strings from a single input (words separated by a space) follow this step.

1) First of all split the string
2) store with index
3) print with single space

public class SpaceRemove {

    public static void main(String[] args) {
        String s = "The   java      is   best";
        String[] temp3 = s.split("\\s+"); // First step
        String a, b, c, d;
        a = temp3[0]; // Store "The" at index 0
        b = temp3[1]; // Store "java" at index 1
        c = temp3[2]; // Store "is" at index 2
        d = temp3[3]; // Store "best" at index 3
        for (String string : temp3) {
            System.out.println(" " + string.trim()); // Print the split string
        }
        System.out.println("You input: " + a + " " + b + " " + c + " " + d); // Print the result with equal space
                                                                                // between two string.
    }
}

What you want to do is split a string.Im assuming you are using java you can simply take your string and do:

String ex = "John Doe";
String[] parts = String.split(ex);
String part1 = array[0];
String part2 = array[1];
