So I have to wait for another 4 weeks. You are lucky you got your SCJP certificate in time. Ever for that I had to go through all this.

Campbell, Could you please explain this in detail?

Alternatively, you can use the complete path of javac.exe in the bin directory of your jdk installation. But setting the PATH environment variable is preferred so that you can use the javac command directly.

Singleton s1 = Singleton.getInstance();
Singleton s2 = Singleton.getInstance();
Singleton s3 = Singleton.getInstance();
it means that the object is created once only, but, it is reference by s1,s2,s3....is it so ?



Yes. For more information please read Singleton Pattern

Suppose if I have a hash algorithm which calculates a hash like this

A B C D E ...... Z
1 2 3 4 5 ...... 26

so for a string "bhanu" my hash will be 2 + 8 + 1 + 14 + 21 = 46
and for the reverse string "unahb" the value is 21 + 14 + 1 + 8 + 2 = 46

In the above case both strings are not the same but the hash value returned is the same. Therefore two objects are not necessarily be equal if the hashcode is same. To determine the equality you have to check for the content of both the strings.
Hi Satnam,
How are you generating the file? Please put the code here.

When you are doing arr[0]+=1 you are manipulating the actual value in the array.
But when you are using you are actually assigning the value in the array to another variable 's' and manipulating it, which will not have any impact on the array. This is similar to

A variable which maintains the number of times a page has been viewed. In this case you have to use a static variable. If you use an instance variable here you will not get the correct count.
