Program 2: Sort the elements of an Array in Descending Order In this approach, we will see how to use Arrays.sort() and Collections.reverseOrder() to sort an array in descending order. The Arrays class of ‘java.util’ package provides the sort method that takes an array as an argument...
当然可以自己编写合适的排序方法,但既然java包里有自带的Arrays.sort排序方法,在数组元素比较少的时候为何不用? Sorting an Array 1.数字排序int[] intArray =newint[] {4,1,3, -23}; Arrays.sort(intArray); 输出: [-23,1,3,4]2.字符串排序,先大写后小写 String[] strArray =newString[] {"z",...
