Plz help i am a newbie

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)));
}
}
}

/* In this above java prog. there is a compiler error,saying :
Note: D:\j2sdk1.4.2_11\bin\CalculateAccnDist.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.

why ??
plz hwlp mwe I am a newbie

That's not an error - it's a warning. The class file should have been created regardless. It tells you that the DataInputStream.readLine method should no longer be used - it is obsolete. The reason, and what to use instead, are outlined in the javadocs for that method.

yes.. DataInputStream is an older version of the InputStreams...but still it can be used. but it is better you can replace it with

BufferedReader inp=new BufferedReader(new InputStreamReader(System.in));

now if u use this inp object in your program then the warning messege which u encountered will not be found..
