LOOP, ARRAY, AND METHOD

• When there are some actions that are

  done over and over again, looping

  statements can be used to ease the

  process.
• • This loop goes through a condition block of code with the reserved keyword while.
  • When the condition is TRUE, it executes the given code inside of its brackets. The loop continues to execute the code when the condition returns TRUE.

  while Loop
• • This looping statement is a variant of the while loop.
  • Where it executes first a statement block, and then the condition will be evaluated.

  do-while Looping
• Allows set of instructions to be performed until a certain condition is reached

  for Loop
• If this statement is encountered inside any looping constructs, the rest of

  the statement block will be skipped, and

  the statement following the statement

  block will be executed.

  break
• • This statement is used only for looping constructs such as for, do-while, and while loops.
  • It allows you to stop the loop before it completes it and reset it to go back to the beginning and start for a new iteration.

  continue
• This uses multiple loops, and it exists inside the body of another loop.

  nested loop
• In a ____ loop, a special value called sentinel is used to stop the

  loop.

  sentinel-controlled
• A ____ statement is a way to exit out of a loop. It differs from a normal break statement in a way that this statement terminates a specific loop while a normal break statement terminates the whole loop.

  Labeled Break
• A ____ statement has the same concept as Labeled Break statement, but instead of terminating a specific loop, this statement skips a specific loop.

  Labeled Continue
• Arrays in JAVA are ____ that allow you to group common data types together.

  data structures
• Arrays in JAVA are ____ that are declared and have a memory address as an actual value.

  objects
• Arrays in JAVA are ____, where once the size of the array is declared, it can no longer ba changed.

  immutable
• Arrays in JAVA are ____, where the size is assigned only in runtime and not a compile time.

  dynamic
• A one-dimensional array is a collection of elements of the same type arranged in a linear sequence.
• Basically, an array is like a list. 
• dataType[] arrayName = new dataType[arraySize];


  one-dimensional array syntax
• SKIP THIS: for lessons only.

  
• in:

  dataType[] arrayName = new dataType[arraySize];

  • Default values - Elements are initialized with default values.
  • Specified size - You can specify the size of the array when you create it.
  • Fixed-size - The size of the array can no longer be changed.
• in:

  dataType[] arrayName = {element1, …, elementn};

  • Concise values - You can initialize the specific values of the array once you declare it.
  • Dynamic size - The size of the array will vary depending on the number of elements you provide.
• To access an array:

  arrayName[index]
• ____ = number of elements in array >= 0

  • Means that ____ corresponds to the number of elements inside an array, and they cannot be less than 0

  arraySize
• A multidimensional array organizes data in more than one dimension; can also be thought of as an array of arrays.
• A two-dimensional array organizes data in two dimensions.
• While a one-dimensional array is like

  a list, a two-dimensional array is like a table or grid.
