String[] array = {"A", "B", "C", "D", "E"}; ArrayUtils.reverse(arr); System.out.println(Arrays.toString(arr)); //[E, D, C, B, A] 5. Conclusion In this short tutorial, we learned to reverse an array using different techniques. We learned to use for-loop, swapping items,...
方法二:使用Collections工具类实现数组反转 publicvoidreverseArray(int[]arr){List<Integer>list=Arrays.stream(arr).boxed().collect(Collectors.toList());Collections.reverse(list);for(inti=0;i<arr.length;i++){arr[i]=list.get(i);}} 1. 2. 3. 4. 5. 6. 7. 上面的代码示例中,我们先将数组...
Learn how to reverse an array using for loops in JavaScript with this comprehensive guide and examples.
Program 2: Reverse a number using for Loop The logic in this program is same as above program, here we are usingfor loopinstead of while loop. As you can see, in this program we have not used the initialization andincrement/decrementsection of for loop because we have already initialized ...
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){ ...
Payel GangulyFeb 02, 2024JavaJava Array In this tutorial content, we will discuss how to reverse anintarray using Java. These structure of reversing an integer array ill need programming knowledge of Java Loop and Java Array. We can perform the reverse operation using three Java programs. Let...
In this approach, all operations are handled within the main method. We start by importing the Stack class from the java.util package, which provides the stack data structure. The input string "Java Program" is defined, and we convert it into a character array. Using a for loop, each cha...
