Plz help me out I am a newbie

Question

import java.io.DataInputStream;
class CalculateAccnDist
     public static void main(String args[])
DataInputStream in = new DataInputStream(System.in);
float a=0.0f;
float u=0.0f;
try
                    System.out.println("Enter the initial speed in m/sec :");
                    u = Float.valueOf(in.readLine()).floatValue();
                    System.out.println("Enter the acceleration of the body :");
                    a =Float.valueOf(in.readLine()).floatValue();
               catch (Exception e) { }
               System.out.println(" Time(s) Distance(m)");
               for(int t=0;t<=60;t=t+10)
                         System.out.println(t + ((u*t) + ((a*t*t)/2)));
I am having two warnings, the warnings are :
Note: D:\j2sdk1.4.2_11\bin\CalculateAccnDist.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
whan I compile with -deprecation , I found the compiler is giving warning in the reading from keyboard statemant i.e. :
u = Float.valueOf(in.readLine()).floatValue();
a =Float.valueOf(in.readLine()).floatValue();
the error is pointed out at ==> in.readLine
for this warning i am also not able to run the program.
Plz help me out, I am a newbie in java.
Thank You

Answer 1

From the API....
readLine()
Deprecated. This method does not properly convert bytes to characters. As of JDK 1.1, the preferred way to read lines of text is via the BufferedReader.readLine() method. Programs that use the DataInputStream class to read lines can be converted to use the BufferedReader class by replacing code of the form:
DataInputStream d = new DataInputStream(in);
with:
BufferedReader d
= new BufferedReader(new InputStreamReader(in));
USE BufferedReader INSTEAD OF DataInputStream
