In this approach, array elements will be initialized in the program. Then as per the algorithm arrange all elements of array such that negative elements are present before positive elements. Open Compiler import java.util.*; public class Main { //main method public static void main(String[] ...
It allows an executing Java program to examine or "introspect" upon itself, and manipulate internal properties of the program. For example, it's possible for a Java class to obtain the names of all its members and display them. 翻译过来就是:反射是指一个运行中的Java程序可以检查、修改自己...
