While loop with break and continue in Julia languages with examples

If you need to execute code block repeatedly until the condition is satisfied, For and while loops are used.

Let’s talk about this while loop in Julia

Julia while loop examples

while loop is used to execute a repeated code block until an condition satisfies

while conditional_statement
    // code block statements
end

conditional_statement is a conditional expression, that always returns the Bool value. If the value is true, It executes code block statements.

Here is an example

k = 1;
while k <= 5
  println(k)
  global k=k+1
end

Output prints values from 1 to 5.

While infinite loop:

Also, if the conditional expression is true and there is no way to break the while, It is in an infinite loop.

k = 1;
while true
  println(k)
end

break: used to break the loop from execution

here is a break usage in the while loop

k = 1;
while k<=10
  println(k)

  if k == 3
    break
  end
  global k=k+1
end

Without a break, It prints the values from 1 to 10. with a break, It prints 1,2,3 value

continue in while loop example: continue used to continue the loop execution by skipping the code after the continue block.

k = 1;
while k<=10
  global k=k+1
 if k % 3 != 0
    continue
  end   
    println(k)

end

Output:

3
6
9
