英尺转换米

import javax.swing.JOptionPane;
public class Foot {
    public static void main(String[] srgs){
        String input = JOptionPane.showInputDialog(null,"请输入米数：","输入框",JOptionPane.QUESTION_MESSAGE);
        double feet = Double.parseDouble(input);
        System.out.println(feet + " feet is " + feet * 0.305 +" meters ");
        
    }
}

编写程序，读入英尺数，将其转换为米数并显示结果。一英尺等于0.305米。
