Java Sixth job

I, entitled

Write a class Computer, class contains a method to find the factorial of n.

The classes are packaged, and Java files App.java another packet introduced packets, Computer definition object classes in the main category,

Calling a method seeking the factorial of n (n is determined by the parameter), and outputs the result.

 

Second, the code segment

(1) Computer-based

CN Package; 

public class Computer { // Write a factorial
 	public static int FAC (int NUM) { 
		int Result = 1; 
		IF (NUM == 1) { 
			return Result; // if 1; return result directly 
		} else { 
		for (int I =. 1; I <= NUM; I ++) { 
			result * = I ; // factorial
 		} 
		return result ; // return result
 
		} 
	} 
}
    		

 (2) App class

Package the Test;
 Import java.util.Scanner; 

Import cn.Computer; // the computer incorporated App class in 
public  class App { 

    / ** 
     * @param args
      * / 
    public  static  void main (String [] args) {
         // Create computer objects 
        Computer COM = new new Computer (); 
        Scanner Reader = new new Scanner (the System.in); // Create a class method Scanner 
        System.out.println ( "enter a number" );
         int m = reader.nextInt (); // the m read from the keyboard
        System.out.println (m + "is the factorial" + com.fac (m));

Third, the results
