M1 Theoretical Evaluation First Task

1. Separators help define the structure of a program

   • () Parentheses
     • 1. Method signatures to contain lists of arguments
       • 2. Expressions to raise operator precedence
         • 3. Narrowing Conversions
           • 4. Loops to contain expressions to be evaluated
   • {} Braces
     • 1. Declaration of types
       • 2. Blocks of statements
         • 3. Array initialization
   • [] Brackets
     • 1. Array Declaration
       • 2. Array value dereferencing
   • <> Angle Brackets
     • Pass parameters to parameterized types
   • ; Semicolon
     • Terminate statements
   • : Colon
     • In the for statement that iterates over an array/collection
   • , Comma
     • Separate arguments in method declarations
   • . Period
     • Separate package names from subpackages and type names, and to separate a field or method from a reference variable

2. Primitives are the most basic data types and contain simple values of a kind

   • Byte
     • Byte-length Integer (8 bits)
   • Short
     • Short Integer (16 bits)
   • Int
     • Integer (32 bits)
   • Long
     • Long Integer (64 bits)
   • Float
     • Single-precision Floating Point
   • Double
     • Double-precision Floating Point
   • Char
     • A Unicode Character
   • Boolean
     • True or False
   • Variables are data placeholders that must have a declared type
     • Reference Types
       • Holds a primitive
     • Primitive Types
       • Provides a reference type to an object
     • Constants are variables whose values cannot be changed

3. Literals are sequences of characters that represent constant values to be stored in variables (Primitives)

   • Integer Literals
     • May be written in decimal, assign values to variables of type byte, short, int, long
   • Floating-point Literals
     • Have a whole number part, decimal point, fractional part, and optional exponent, assign values to variables of type float and double
   • Boolean Literals
     • Written as true or false, assign values to variables of type boolean
   • Character Literals
     • Written as a Unicode character, assign values to variables of type char
