reverseArray[i] = originArray[length - i -1]; } 方法三 将原数组通过前后交换实现逆序 publicvoidarrayReverse3(){inttemp=0;for(inti=0; i < length /2; i++) { temp = originArray[i]; originArray[i] = originArray[length - i -1]; originArray[length - i -1] = temp; } } 主函...
方法一:使用循环实现数组反转 publicvoidreverseArray(int[]arr){intstart=0;intend=arr.length-1;while(start<end){inttemp=arr[start];arr[start]=arr[end];arr[end]=temp;start++;end--;}} 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 上面的代码示例中,我们使用了一个while循环来实现数组的反转...
importjava.util.Arrays;publicclassArrayReverseExample{publicstaticvoidmain(String[]args){int[]array={1,2,3,4,5};intstart=0;intend=array.length-1;while(start<end){inttemp=array[start];array[start]=array[end];array[end]=temp;start++;end--;}System.out.println("Reversed array: "+Arrays.to...
import java.util.Arrays; public class ReverseArray { public static void main(String[] args) { int[] arr = {1, 2, 3, 4, 5}; Arrays.reverse(arr); for (int i : arr) { System.out.print(i + " "); } } } 运行上述代码,输出结果为:5 4 3 2 1,可以看到数组已经被成功反转。 2、...
int[] array = {1, 2, 3}; Collections.reverse(Arrays.asList(array)); //Does not reverses the array 2. Swapping Array Elements in For Loop Another simple and straightforward way is to iterate through the array swapping them from the beginning position with the elements in the last position...

int变成string，string变成chararray，chararray倒序遍历变回string string变回int 记得判断正负。也可以用/10的余数取数字然后再乘10加回来 例如：public String reverseSting(String inputString) { char[] inputStringArray = inputString.toCharArray();String reverseString = "";for (int i = input...
public int reverse(int x) { boolean neg = x < 0; x = Math.abs(x); int count = 0; int temp = x; while (temp != 0) { temp /= 10; count++; } if (count==0){ return 0; } int[] array = new int[count]; for (int i = count - 1; i >= 0; i--) { array[count...
