这里有一个简单快速的解决方案。希望能有所帮助!

public int[] reverse(int[] arr) {
    for(int i = arr.length; i > 0 ; i--){
        System.out.print(arr[i-1] + " ");
    }
    return arr;
}

简单for循环!

for (int start = 0, end = array.length - 1; start <= end; start++, end--) {
    int aux = array[start];
    array[start]=array[end];
    array[end]=aux;
}

public class ArrayHandle {
    public static Object[] reverse(Object[] arr) {
        List<Object> list = Arrays.asList(arr);
        Collections.reverse(list);
        return list.toArray();
    }
}

反转一个int数组，你交换元素直到你到达中点，像这样:

for(int i = 0; i < validData.length / 2; i++)
{
    int temp = validData[i];
    validData[i] = validData[validData.length - i - 1];
    validData[validData.length - i - 1] = temp;
}

你这样做的方式是，你交换每个元素两次，所以结果与初始列表相同。

这里是一个简单的实现，反转数组的任何类型，加上全/部分支持。

import java.util.logging.Logger;

public final class ArrayReverser {
 private static final Logger LOGGER = Logger.getLogger(ArrayReverser.class.getName());

 private ArrayReverser () {

 }

 public static <T> void reverse(T[] seed) {
    reverse(seed, 0, seed.length);
 }

 public static <T> void reverse(T[] seed, int startIndexInclusive, int endIndexExclusive) {
    if (seed == null || seed.length == 0) {
        LOGGER.warning("Nothing to rotate");
    }
    int start = startIndexInclusive < 0 ? 0 : startIndexInclusive;
    int end = Math.min(seed.length, endIndexExclusive) - 1;
    while (start < end) {
        swap(seed, start, end);
        start++;
        end--;
    }
}

 private static <T> void swap(T[] seed, int start, int end) {
    T temp =  seed[start];
    seed[start] = seed[end];
    seed[end] = temp;
 }  

}

下面是相应的单元测试

import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;

import org.junit.Before;
import org.junit.Test;

public class ArrayReverserTest {
private Integer[] seed;

@Before
public void doBeforeEachTestCase() {
    this.seed = new Integer[]{1,2,3,4,5,6,7,8};
}

@Test
public void wholeArrayReverse() {
    ArrayReverser.<Integer>reverse(seed);
    assertThat(seed[0], is(8));
}

 @Test
 public void partialArrayReverse() {
    ArrayReverser.<Integer>reverse(seed, 1, 5);
    assertThat(seed[1], is(5));
 }
}

private static int[] reverse(int[] array){
    int[] reversedArray = new int[array.length];
    for(int i = 0; i < array.length; i++){
        reversedArray[i] = array[array.length - i - 1];
    }
    return reversedArray;
}
