import java.util.Scanner;

public class Test {

public static void main(String[] args) {
double[] num = new double[5];
Scanner in = new Scanner(System.in);
double count = 0;

for (int i = 0; i < num.length; i++) {
System.out.println("请输入第" + (i + 1) + "笔购物金额");
num[i] = in.nextDouble();
}

System.out.println("序号 \t金额（元）" );

for (int i = 0; i < num.length; i++) {
System.out.println((i + 1) + "\t" + num[i]);
count += num[i];
}

System.out.println("总金额\t" + count);
}
