Lesson 1

• The while loop is a fundamental iterative structure in Java programming that allows you to repeat a code block as long as a specified condition is true. 
• The while loop provides a simple and flexible way to perform repetitive tasks and control program flow based on conditions
• In while loop, the condition is evaluated before each iteration of the loop. If the condition is true, the code block is executed.
• In while loop, if the condition is false initially, the code block is skipped, and the loop terminates without executing any statements.
• The while condition can be any expression that evaluates to a boolean value (true or false).
• By using while loops effectively, you can automate repetitive processes, control program flow based on changing conditions, and make your code more efficient and flexible.
• The do-while loop is a type of iterative structure in Java programming that allows you to repeat a code block at least once, and then continue repeating it as long as a specified condition is true.
• The do while loop is similar to the while loop, but with the key difference that the condition is checked at the end of each iteration.
• Do-while loops are valuable in programming as they ensure that a code block is executed at least once before checking the condition.
• The do while loop allows you to perform an action first and then decide whether to repeat it based on a specified condition.
• syntax of the while loop: while (condition) {

  // Code block to be executed

  }
• syntax of do while loop:

  do {

  // Code block to be executed

  } while (condition);
• In do-while loop, the code block is executed first, and then the condition is evaluated. If the condition is true, the loop continues executing the code block. If the condition is false, the loop terminates, and program control moves to the next statement after the loop.
• do-while - they are useful in situations where you want to perform an action first and then decide whether to repeat it based on a condition.
