import java.io.*;

class InputTest
{
public static void main(String []args) throws IOException
{
byte [] bytes = new byte[20];
BufferedInputSt ream bis = new BufferedInputSt ream(System.in) ;
DataInputStream dis = new DataInputStream (bis);
String str = dis.readLine();

DataOutputStrea m dos = new DataOutputStrea m(System.out);
dos.writeUTF(st r.toUpperCase() );

dos.close();

System.out.prin tln("End of program"); // this willnot be printed

}
}
This is the result when i try to complie this code help me out...!!!Java\jdk1.5.0\b in>javac InputTest.java


Note: InputTest.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecati on for details.

1.) Please use code tags next time when posting code.
2.) You could do as the compiler says and recompile with -Xlint checked and see for yourself what the fuss is about.
3.) Why don't you use java.util.Scann er for getting input from the console?

Just do

javac -Xlint YourClassName.java

when compiling the class. You can then check the API to see what has now replaced that method.

--->compiler said nothing
Why don't you use java.util.Scann er for getting input from the console?

how to use java.util.Scann er ???

[raveendrabikkina]

ok got the solution but i think this is because of the jdk version change...

thnq buddy

[r035198x]

Y...>compiler said nothing
..

The compiler told you the exact line number where the warning is and and even went as far as to give the exact method name that you used which is deprecated.

how to use java.util.Scann er ???

java.util.Scann er

P.S A warning is not the same as an error. The program compiles, creates the .class file and runs even if the compilation produced a warning.
