大家看看,这个程序有错吗?
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class InputStringTwo {

/**
* @param args
* @throws IOException
* @throws NumberFormatException
*/
public static void main(String[] args) throws NumberFormatException, IOException {
// TODO 自动生成方法存根
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int i,max=0,min;
int a[]=new int[5];
System.out.println("请输入五个数:");
for(i=0;i<a.length;i++)
{
a[i]= Integer.parseInt(br.readLine());
}

for(i=0;i<a.length;i++)
if(a[i]>max){
max=a[i];
}
min=a[0];
for (i=0;i<a.length;i++){
if (min>a[i]){
min=a[i];
}
}
System.out.println("max="+max);
System.out.println("min="+min);
}
}
还有,BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); 是什么意思?
new InputStreamReader(System.in); 又是什么意思/
