Through the shell example to learn the syntax of the loop structure: the so-called useful is to learn to use it all the time. It is useless if you forget it. On the other hand, it is very likely that the leaders have great expectations for you. So what we learn is often used in practice as our own. Www.2cto.com is actually the best way to learn is to first touch the actual things and use practice to verify

For Next loop, you have to perform a number of sets of code multiple times. The syntax is as follows:For counter = Initial_value to Finite_value [step increment]StatementsNextThe For statement specifies the counter variable and its initial and limited value. The next statement increases the fight against a variable. Can The selected step keyword allows you to specify counter variables by adding or decreasi

There are two types of enhanced for loops, which iterate through the array and implement the container for the Iterable interface. Javac uses the Visitforeachloop () method to implement the syntax sugar, the code is as follows:/** Translate away the Foreach loop. */Public void Visitforeachloop (Jcenhancedforloop tree) { if (types.elemtype (tree.expr.type) = = null) Visititerableforeach
