新手求解错误
import java.util.Scanner;

public class cs {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner in=new Scanner(System.in);
String s[]=new String[10];
double d[]=new double[5];
for(int j=0;j<3;j++)
{
System.out.print("输入购买的物品:");
s[j]=in.nextLine();
System.out.print("输入物品的单价:");
d[j]=in.nextDouble();
}
}

}

换成下面这样正常了

Java code

import java.util.Scanner;public class Cs {    public static void main(String[] args) {// TODO Auto-generated method stub        String s[]=new String[10];        double d[]=new double[5];        for(int j=0;j<3;j++)        {            Scanner in=new Scanner(System.in);            System.out.print("输入购买的物品:");            s[j]=in.nextLine();            System.out.print("输入物品的单价:");            d[j]=in.nextDouble();        }    }}

你这写就没有问题！

import java.util.Scanner;
public class cs {
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner in = new Scanner(System.in);
		String s[] = new String[10];
		double d[] = new double[5];
		for (int j = 0; j < 3; j++) {
			System.out.println("输入购买的物品:");
			s[j] = in.nextLine();
			System.out.println("输入物品的单价:");
			d[j] = in.nextDouble();
		}
	}

}
