import java.util.*;

public class Lautturi {
	public static void main(String[] args) {
		int[] intArray = { 1,2,3,4,5,6,7,8,9,10 };
		System.out.println(Arrays.toString(intArray));
		for(int i = 0;i<intArray.length/2;i++) {
			int temp = intArray[i];
			intArray[i] = intArray[intArray.length-i-1];
			intArray[intArray.length-i-1] = temp;
		}
		System.out.println(Arrays.toString(intArray));
	}
}

output:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
