This article explains about do loop or do-while loop in java with examples.

do-while statement provides a form of loop. do loop repeats the statement or statements while the expression is true. It stops when the expression becomes false.

Note that do-while loop is unique because it will always execute the code within the loop at least once, since the expression controlling the loop is tested at the bottom of the loop.

Syntax of do-while loop

do
{
statements;
}while(expression);

  public static void main(String args[])
  {
int i  = 1;

System.out.print("Numbers : ");

do
{
System.out.print(i + " ");
i++;
} while(i >= 10)
  }
}
