71) Iterating the collections
72) inner classes
73) Anonymous classes
74) Functional interfaces
75) Lambdas
76) Java collections : streams / lambdas to perform search / traverse / filter
77) Planning the data structures for business layer
78) Designing / implementing business layer and its testcases
79) Designing / implementing presentation layer (TUI)

80) GUI (AWT) - components, layout manager, positioning / sizing
81) Event Handling / Listeners

83) Model / View ( Table / Abstract Table Model)
84) FileChooser (Save / open dialogs)
85) Creating PDF
86) Changing the presentation layer from TUI to GUI without changing a single line of Business layer and data layer.

90) Joins
91) JDBC code to perform insert/update/delete/select operations
92) MySQL
93) Procedures / functions / triggers
94) Invoking procedures / functions through jdbc code
95) Changing data layer our application, without changing the presentation layer and the business layer
96) Network programming / socket programming

100) Multithreading - the modern approach - Executor Service / thread pools
101) the concept of Future tasks
102) Creating a multithreaded server
103) writing protocol for network programming
104) data transmission in form of chunks of byte array
105) File tranfer application
106) JSON , google gson

107) Converting the application that we created earlier to a network application without changing single line of presentation
layer, business layer and data layer. By placing proxy classes between the presentation layer and the business layer.
108) Creating a socket framework. One who uses this framework  will be able to write network applications without writing a single
line related to network / socket programming.
109) The new features introduced from java - 10 to 14
