在java中高效地将字符串解析为带2个浮点数的类对象

import java.util.Scanner;

public class StringParser {
    public static void main(String[] args) {
        String input = "3.14 2.718";
        Scanner scanner = new Scanner(input);

        double number1 = scanner.nextDouble();
        double number2 = scanner.nextDouble();

        MyClass myObject = new MyClass(number1, number2);
        System.out.println(myObject);
    }
}

class MyClass {
    private double number1;
    private double number2;

    public MyClass(double number1, double number2) {
        this.number1 = number1;
        this.number2 = number2;
    }

    @Override
    public String toString() {
        return "MyClass{" +
                "number1=" + number1 +
                ", number2=" + number2 +
                '}';
    }
}
