下面我想写成键盘输入shuru的值，然后pc再输出一边。达到了解io的目的。但是始终javac时错误，请指点。
import java.io.*;
public class ice
{
public static void main(String[] args)
  {
  float shuru
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
  String inputLine = in.readLine();
  shuru = Float.valueOf(inputLine).floatValue();
System.out.println( shuru );
  }
}

import java.io.*;
public class Yn{
public static void main(String args[])throws IOException
{
int a=0;
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String str=in.readLine();
a=Integer.paseInt(str);//我是在网吧打的，不知道这个单词对不对，泥仔细看看
System.out.println("刚才输入的是:"+a);
//当输入整数时正常，输入字符会有输入异常

}

}
