Java Fundamentals-Enhanced for loop

The java1.5 version introduces an enhanced for loop, which is similar in principle to for loops.

Syntax declaration: for (expression: conditional expression)

Example: For(String str: set)

Explanation: Set represents the set set, and STR represents the type stored in the set set.

The code examples are as follows:

Set New Hashset<string>(); Iteratorset while (It.hasnext ()) {  =  It.next ();  System.  out  forset) {      System.  out . println (str);}
