Thread: Understanding array operators

Hello!

I am having trouble understanding how thing work with arrays specificly what the "=" operator represents. I've written a really simple code and I'm trying to fully understand what is happening, I am having a few doubts and some help would be appreciated. Thank you!

 
public class test {
	public static void main(String[]args) {
 
		int[] numbers = {1,2,3,4,5};
 
		int temp;
 
		int start = 0;// first number in the array (1)
 
		int end = numbers.length -1;//last number in the array(5)
 
		while(start < end) {// keep going until the numbers "collide"
			temp = numbers[start];//temp now holds the value of start(1)
 
			numbers[start] = numbers[end];// this is the part that confuses me
 
			numbers[end] = temp;//this as well
 
			start = start + 1;// increase the value of start by 1
		    end = end -1;// decrease the value of end by 1
 
		}
 
		Out.println(java.util.Arrays.toString(numbers));
	}
}

Great answer thank you!
