import java.io.*;
public class Conversion
{
public static void main(String[] args) throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println(br);
Integer abc=new Integer(br.toString());
int vale=abc.intValue();
System.out.println(vale);
}
}
怎样从输入流读取字符串再转换成整形,若不能转换抛出异常
上面是我写的是错误的
public class Conversion
{
public static void main(String[] args) throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println(br);
Integer abc=new Integer(br.toString());
int vale=abc.intValue();
System.out.println(vale);
}
}

}
}
这样就OK了
