Java中增强的for循环的语法是什么? [英] What is the syntax of the enhanced for loop in Java?

问题描述

已要求我在编码中使用增强的for循环.

I have been asked to use the enhanced for loop in my coding.

我只被教过如何使用传统的for循环，因此不知道它与增强型for循环之间的区别.

I have only been taught how to use traditional for loops, and as such don't know about the differences between it and the enhanced for loop.

增强的for循环与Java中传统的for循环有何不同?

How does an enhanced for loop differ from a traditional for loop in Java?

我应该注意哪些教程往往不提及的复杂之处吗?

Are there any intricacies that I should look out for which tutorials tend not to mention?

推荐答案

增强了循环力:

for (String element : array) {
    // Do something with element of type String
    System.out.println(element);
}

传统for循环:(

for (int i=0; i < array.length; i++) {
    // Reference to the item in array[position]
    String element = array[i];
    // More code using String element
}
