JAVA - Coggle Diagram

- - - - has synchronised methods
    - - More efficent
      - Newer
      - It does not have synchronised methods
- - - - Means implictly a double will never be converted to a int
- - - - Note that end index not included
- - - - new Vector<type>();
- - - - nextInt
        
        also specidy the upper bond like if nextInt(1000) get numbers from 0 to 999
      - nextDouble
      - nextBoolean
- - - - Errors
      - Runtime Exceptions
    - - All Exceptions other than the Runtime and the Errors
        
        Must be declared as a part of signature of the method
  - - - How to catch exceptions
        
        Only one way Use a try catch block
      - Where you catch the exceptions
        
        Can be the inner most method where the exception occurred or the methods that called that method or above it ...
        
        It is caught when it encounters a try catch block for the first time when searching for it from the inner most method where the exception occured to the outermost
    - - Then program terminates and JVM prints to console
- - - - Why to use this rather than the reference of type of that class ?
        
        Is there a difference
