Taking input frm user-----DataInputStream is a deprecated class. Use BufferedReader.

......came up with a better solution, including, user I/P, for float, integer and String as well, please......post...for other data types asap....

import java.io.*;
class inp
{
public static void main(String args[])
{
try{BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
String name;
int age;
float marks;
System.out.println("Enter your name : ");
name=br.readLine();
System.out.println("Enter our age: ");
age=Integer.parseInt(br.readLine());
System.out.println("Enter your marks: ");
marks=Float.valueOf(br.readLine()).floatValue();
System.out.println("\nName : "+name+"\nAge: "+age+"\nMarks: "+marks);
}
catch(Exception e)
{}
}
}

......the older one.....

import java.io.*;
class inp
{
public static void main(String args[])
{
try
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
String name;
System.out.println("Enter your name : ");
name=br.readLine();
System.out.println("Entered name : "+name);
}
catch(Exception e)
{}
}
}
