Last warning: your next post without a proper Subject will be removed!

You're just reading the first 3 characters.
http://java.sun.com/j2se/1.4.2/docs/api/java/io/BufferedReader.html#read()
You would have to parse the numbers from the input (line).

下面的这个程序
为什么输入的a.b.c 的值与输出的不同啊？？
import java.io.*;
import java.util.*;
public class equation {
public static void main(String[] args) throws IOException,NoSuchElementException{
int a=0;
int b=0;
int c=0;
float delt;
float x1,x2;
try{
InputStreamReader reader=new InputStreamReader(System.in);
BufferedReader input=new BufferedReader(reader);
System.out.println("Please input a,b,c:");
int d[]=new int[3];
for(int i=0;i<3;i++)
d[i]=(int)input.read();
a=d[0];b=d[1];c=d[2];
System.out.println("a="+d[0]+", b="+d[1]+", c="+d[2]);
} catch(IOException e){System.out.println(e.getMessage());}
catch(NoSuchElementException e){System.out.println(e.getMessage());}
}
}
