How to I change the position in arrays

Alright, so what I want to do is presenting an array backward... so if I have an array of length 10 (1,2,3,4,5...) I want them to come out as 10, 9, 8...

I was thinking something along these lines:

public class uppg1 {
int[] array= {1,2,3,4,5,34,7,8,9,10};
int i;

public void summa(){

for (i=0; i<array.length; i++);{
for (int j=i+10; j<array.length; j++)
{
int tmp=array[i];
int array[i]=array[j];
array[j]=tmp;
}

}
}

buuut it doesnt seem to work, any tip? :)

You don't need a nested loop to reverse an array and btw the loop boundaries of your inner loop suck big times ;-)

Code:

---

for (int i= 0; i < array.length; i++) {
  int j= array.length-1-i;
  int tmp= array[i]; array[i]= array[j]; array[j]= tmp;
}

Code:

---

for (int i= 0; i < array.length; i++) { // array.length / 2, perhaps?
  int j= array.length-1-i;
  int tmp= array[i]; array[i]= array[j]; array[j]= tmp;
}
