使用Java计算长方形体积

import java.util.Scanner;
public class tiji {
	
	public double TiJiFangFa(double chang,double kuan,double gao){
		double rectangletiji = 0;
		rectangletiji = chang*kuan*gao;
		return rectangletiji;
	}
	
	public static void main(String[] args) {
			  Scanner sc = new Scanner(System.in);
			  double a,b,c;
			  System.out.println("输入长方形的长：");
			  a = sc.nextDouble();
		      System.out.println("输入长方形的宽：");
		      b = sc.nextDouble();
		      System.out.println("输入长方形的高：");
		      c = sc.nextDouble();
		      tiji result = new tiji();
		      System.out.println("长方形的体积是："+result.TiJiFangFa(a,b,c));
	}
}

输出：
