MOD 3

• Repetition control structures are Java statements that allows to execute specific blocks of code a number of times.
• Three types of repetition control structures:

  1. for loops
  2. while
  3. do-while
• For loop allows execution of the same code a number of times
• Initialization - initializes the loop variable.
• Condition - compares the loop variable to some limit value
• Step / iteration - updates the loop variable
• For statement:

  1. Initialization
  2. Condition
  3. Step / iteration
• while loop - statement or block of statements that is repeated as long as some condition is satisfied.
• The statements inside the while loop are executed as long as the boolean_expression evaluates to true
• The statements inside a do-while loop are executed several times as long as the condition is satisfied.
• The main difference between a while and do-while loop is that, the statements inside a do-while loop is executed at least one
