Basic Java Program to Reverse anintArray In this first example, we take the size of array and the elements of array as input. We consider a functionreversewhich takes the array (here array) and the size of an array as the parameters. Inside the function, we initialize a new array. The...
On Crunchify, we have published more than 500 Java Tutorials and in this tutorial we will go over steps on how to reverse a string in Java? There are 7
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 = inputS...
In the second iteration, we swap the second and second-last elements. The same swapping goes on in the for-loop until we hit the middle of the array, at this time the array has been reversed. String[] array = {"A", "B", "C", "D", "E"}; for (int i = 0; i < array....
