how can we make our java program run from any location irrespective of its original location ?

ANS----------------->



Use classpath support.

eg.
|------->java
          |------->pd.java

pd.java
public class pd{
public static void main(String ars[]){
     System.out.println(" welcome to java ");
}
}

E:\java>javac pd.java
E:\java>java pd
D:\movie>java pd (error)





Solution:
Add the address location pd.class to classpath environment variable.

Variable name :  CLASSPATH
Value              :  E:\java
                         press ok (3 times)

D:\movie> java pd.java (success)
