Java Basics (third day of formal classes)

Ask for a number of numbers: You can first by removing the remainder->321 321/100=3 321/10%10=2

Method: Note The static decoration method call variable or method requires static decoration

Methods cannot be nested in defined methods, only by calling, return only one value in a method

The form participates in the actual parameter difference, the method passes the parameter to the method the argument.

Recursion: End Condition

Import Java.util.Scanner;

public class Demo1 {

public static void Main (string[] args) {

SYSTEM.OUT.PRINTLN (Num (5));

}

public static int num (int i) {

if (i==0) {

return 1;

}

System.out.println (i);

Return I*num (i-1);

}

}
