Addendum: Java Relevance-1

• References of similarities and differences between Objective C and Java

• NSString → String

• NSMutableString → StringBuffer

• You can subclass the NSString or Collection but it is not recommended.

• In Cocoa many classes are implemented in class clusters which are hidden from developer. This is quite same the way JVM internally has its own mapping for runtime.

• At high level Collection classes exists in both.

• NSDictionary → Hashtables

• NSArray → Array

• NSEnumerator → Enumeration

• NSNumber → Integer, Float, Double

• Garbage Collector introduced in Objective C 2.0 available in Java from beginning.
