    8. initializing the variable

  4. Methods

    1. class (static)
    2. instance
    3. parameter lists
    4. return type (may be void)
    5. abstract
    6. Special ones:
      1. constructor

  1. Arrays

    1. linear indexed data structure
    2. all elements of same type
    3. fixed size
    4. variable references an array data structure
    5. declaring an array
    6. initializing the elements
      1. new
      2. initializer

      5. summing the elements
      6. finding the minimum or maximum
      7. shuffling
      8. shifting
      9. swapping
      10. for-each (advanced for loops) with arrays
      11. as method parameters and return values
