Looping in Java, a brief look at the various loops and how they can be applied

One of the great features of any programming language is the ability to repeat blocks of code, sometimes indefinately, sometimes until a certain condition is met, or for a set number of iterations.
Luckily, Java comes with several flavours of loops, let have a brief look at our options
- The “for” loop – The for loop is generally used when you know in advance how many iterations the loop must execute. The for loop enables you to setup a repeatable code block with access to the index(es)

while (boolean_expression);
So as we can see, the actual body of the loop gets executed at least once before the boolean expression is ever evaluated. Now lets have a look at a real example :
