Recompile with -deprecation for details.

Have you compiled with that option? If not you need to do so.
You are using an old method that author of the class wants to get rid of.

You are using an old method that author of the class wants to get rid of.

This means that the method can be removed from the java pack at any time, which will stop your program from working...

This is how you handle compiler deprecation warnings:

C:\jexp>javac stringip.java
Note: stringip.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

C:\jexp>javac -Xlint:deprecation stringip.java
stringip.java:7: warning: [deprecation] readLine() in java.io.DataInputStream 
has been deprecated
            String a=ds.readLine();
                       ^
stringip.java:8: warning: [deprecation] readLine() in java.io.DataInputStream 
has been deprecated
            int d=Integer.parseInt(ds.readLine());
                                     ^

C:\jexp>

Look up the readLine method in the DataInputStream class to see what its use has been replaced with.
