1. Can You tell us the range of 'Char Type' ?

2. Can you explain 'wrapped classes' ?

3. Please Number the bits used to represent the Unicode & UTF-16 ?

4. What is synchronization ?

5. Explain the step to convert the number IP address in to a hostname ?

6. Is there any unoverloaded methods in Java ?

7. What are the different identifiers of a Thread ?

8. Can you explain abou Externalizable ?

9. Is it possible to define private and protected modifiers for variables in interfaces ?

1. The range of the char type is 0 to 2^16 - 1.

2. Wrapped classes are the type of classes which allow primitive types to be accessed as objects.

3. Unicode need 16 bits and UTF-16 uses 16-bit and larger bit patterns.

4. Synchronization is the capability to control the access of multiple threads to shared resources.

5. String hostname = InetAddress.getByName("101.10.013.19").getHostName

6. yes,there are methods. Some classes like DataOutputStream have unoverloaded methods like writeInt() and writeByte().

7. Different identifiers of a Thread are:
R - Running Thread,
S - Suspended thread,
CW - Thread waiting on a condition variable,
MW - Thread waiting on a monitor lock,
MS - Thread suspended waiting on a monitor lock

8. Externalizable is an Interface that extends Serializable Interface. It sends data into Streams in Compressed Format.

9. No
