Introduction to recursion + recursion examples (use recursion to output 1~100)

1. Definition: Recursion is an idea, and its application in programming is reflected in the method calling method itself.

2. Example;Use recursive method to print 1 to 100

public class Print1_100Myself {
   
   public static void printx(int start,int end){
     if(start>end) {
       return;
     }else {
       System.out.println(start);
       start++;
       printx(start, end);
     }
     
   }
   
//主函数(main方法)，程序入口(此处启动,调用printx方法,输入参数调用此方法)
   public static void main(String[] args) {
     printx(1,100);
   }
}
