Loop Statements

  • Repetition: Repetition or looping is used to repeat a task in a program as many times as necessary.

  • Loops in Java: for, while, and do-while are 3 different ways Java provides for repetition.

  • Structure of a loop: All loops have 4 parts:

    • Initialization: To set the variables to a good starting point

    • Check of Condition: To evaluate the conation(s) to determine if there is a need to continue

    • Task: The process that needs to be repeated.

    • Reset condition: Changing the values to reset the condition, to ensure proper termination of the loop

  • For loop Syntax: for ( initialize ; Check condition; Reset condition) Task ;

  •  for (int I = 0 ; I < 5 ; I++)    System.out.println(I); // Prints I (0-4)
  • While loop syntax:

  •  Initialize condition;           int  I = 0 ; while (Check condition) {       while ( I < 5 ){    Task;                            System.out.println(I);    Reset condition;                 I++ ; }                               }
  • Do_while loop Syntax : This type of a loop is different in the way that it forces the task to be done at least once, by combing the initialization and reset of the condition and checking the condition at the end of the loop instead of beginning.

  •  Declare variables               int I ;                                Scanner KB = new Scanner(System.in); do{                             do{    Task                            System.out.println("Enter an integer                                          between 1 and 5 :");    Set/reset the condition;        I = KB.nextInt(); }while (Condition true)         } while ( I < 1 || I > 5);
