Java 2.3(将英尺转换成米)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。下面是运行示例：

Enter a value for feet(输入英寸的值): 16.5

16.5 feet is 5.0325 meters(16.5英尺是5.0325米)

package Second;
import java.util.Scanner;
public class FeetAndMeters {

	public static void main(String[] args) {
		System.out.println("Enter a value for feet:");
		Scanner input = new Scanner(System.in);
		double feet = input.nextDouble();
		
		double meters = 0.0;
		meters = feet * 0.305;
		System.out.println(feet + " feet is "+meters +"meters");
	    }
	}

输出

Enter a value for feet:
16.5
16.5 feet is 5.0325meters
