在java中如何在一行中获取多个数据类型？

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.print("请输入一个整数：");
        int num1 = scanner.nextInt();

        System.out.print("请输入一个浮点数：");
        double num2 = scanner.nextDouble();

        System.out.print("请输入一个字符串：");
        String str = scanner.next();

        System.out.println("输入的整数是：" + num1);
        System.out.println("输入的浮点数是：" + num2);
        System.out.println("输入的字符串是：" + str);

        scanner.close();
    }
}
