I applied enhanced for loop on a 2d array. I am getting unexpected output. Please check the code public class pr { public static void main(String[] args) { int listoflist[][]= {{45,34,23},{43,2}}; for (int[] j:listoflist) { // System.out.println(j[0]); for (int k:...
For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop. We have moved the counter increment and the termination statements inside the loop body. The statements are the same as the previous version. int[]array=newint[]{0,1,2,3,...
(Java for loop Evolution) We will work on an example for displaying names of actors from aCollection. For the sake of simplicity let’s take aListand set this up: 我们将通过一个示例来显示Collection中演员的姓名。 为了简单起见,让我们列出一个列表并进行设置: List<String> actors = Arrays.asLi...

The search criteria are encapsulated in a method, an improvement over the previous example. The test conditions can be reused and changes flow back throughout the class. However there is still a lot of repeated code and a separate method is still required for each use case. Is there a bett...
for ( int number: computeNumbers() ) sum += number; Limitations Sometimes you need access to the iterator or index during iteration. Intuitively it seems like the enhancedforloop should allow this. It doesn't. Take the following example: ...
