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...
Learn how to reverse or invert an array in Java. A reversed array is of equal size to the original array and contains the same items but in the reverse order. String[] array = {"A", "B", "C", "D", "E"}; String[] reveresedArray = {"E", "D", "C", "B", "A"}; 1...
public static void main (String[] args) throws java.lang.Exception { int[] a= {1,2,4,5}; System.out.println( Arrays.toString(reverseArray(a))); } public static int[] reverseArray(int[] nums){ int begin=0; int end= nums.length -1;while(begin <end){ swap(nums, begin++, end-...
System.arraycopy(a, base1, tmp, cursor1, len1); // Move first element of second run and deal with degenerate cases a[dest++] = a[cursor2++]; if (--len2 == 0) { System.arraycopy(tmp, cursor1, a, dest, len1); return; } if (len1 == 1) { System.arraycopy(a, cursor2,...

theComparableinterface. (The natural ordering is the ordering imposed by the objects' owncompareTomethod.) This enables a simple idiom for sorting (or maintaining) collections (or arrays) of objects that implement theComparableinterface in reverse-natural-order. For example, supposeais an array of...
String reversePalindrome = new String(charArray); System.out.println(reversePalindrome); } } Running the program produces this output: doT saw I was toD To accomplish the string reversal, the program had to convert the string to an array of characters (firstforloop), reverse the array into ...
