如何在数组内部循环？

Question

[ASK] How to loop inside array? this is right?

weather_data = new Weather[]
{
for (i= 0; i < listOfMenu.size(); i++) {
new Weather(R.drawable.dring1, listOfMenu.get(0)),
}
};

Answer 1

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
String element = elements[i];
String nextElement = elements[i+1];
}

Answer 2

It's simple, let me show you.

To enter inside a array and go around with this array you use a simple for, as you did:

for ( parameter : arrayName)
    instruction

If by example you want to print the values that are inside the array, you should do like this:

int[] arrayNum = {87, 68, 52, 5, 49, 83, 45, 12, 64};   /
for(int i : arrayNum) 
System.out.printf("Array Elements" + arrayNum[i]);
 }

I didn't quite understand what you are trying to do, but my answer was a direct response to your question.

Answer 3

Short answer, you can't.

Long answer is that it isn't apart of the Java syntax. You have the code to loop through it right there, all you have to do is move it outside. Check out this handy snippet:

    Weather[] weather_data = new Weather[listOfMenu.size()];
    for (i= 0; i <= listOfMenu.size()-1; i++) {
        weather_data[i] = new Weather(R.drawable.dring1, listOfMenu.get(i));
    }
