stuinfoinput.java

（1） 设计和编写代表矩阵的Matrix类。该类包括矩阵行列数变量int rows和int cols

import java.util.*;
public class StuInfoInput{
	public static void main(String args[]) throws IOException{
		Vector stuList=new Vector();
		System.out.println("Please input the name of the student.");
		String s=null;
		boolean done=false;
		String ans;
		InputStreamReader ir;
		BufferedReader in;
		ir=new InputStreamReader(System.in);
		in=new BufferedReader(ir);
		while(!done){
			s=in.readLine();
			stuList.addElement(s);
			System.out.println("More student's name? (y/n):");
			ans=in.readLine();
			if((ans.equals("n"))||(ans.equals("N"))){
				done=true;
			}
			else{
				System.out.println("Please input anther student's name.");
			}
		}
		int position;
		int vectorSize=stuList.size();
		System.out.println("The student in the list are:");
		for(position=0;position<vectorSize;position++){
			System.out.println((String)(stuList.elementAt(position)));
