Simple Java logic code (Logging Platform, Bubble sorting, daffodils, retrieval, recursion), java
1. Logging in

Simple and small code. To commemorate the past and bless new people.

 1 public static void main(String[] args){ 2     int[] ld = {1,4,2,10,8,9,5}; 3     int max = ld[0]; 4     for(int i = 1;i<ld.length;i++){ 5         if(ld[i]>max){ 6             max=ld[i]; 7         } 8     } 9     System.out.print(max);10 }

2. Bubble Sorting

Or simple small code, Bubble sorting. To commemorate the past and bless new people.

 1 public static void main(String[] args){ 2     int[] ld = {6,10,2,4,11}; 3     int aa; 4     for(int i = 0;i<ld.length-1;i++){ 5         for(int j = 0;j<ld.length-1-i;j++){ 6             if(ld[j]>ld[j+1]){ 7                 aa=ld[j]; 8                 ld[j]=ld[j+1]; 9                 ld[j+1]=aa;10             }11         }12     }13     for(int a = 0;a<5;a++){14         System.out.println(ld[a]);15     }16 }

3. daffodils

Or a simple little code, the number of daffodils. To commemorate the past and bless new people.

Public static void main (String [] args) {int I = 0; System. out. print ("daffodils:"); for (int a = 100; a <= 999; a ++) {int B = a % 10; int c = a/10% 10; int d = a/100; int all = B * B + c * c + d * d; if (all = a) {System. out. print (all + ","); I ++ ;}} System. out. println ("Total" + I + ");}

4. Number of replies

It is also a simple small code, the number of replies. To commemorate the past and bless new people.

Public static void main (String [] args) {String B = "Haha"; for (int I = 0; I <B. length ()/2; I ++) {char first = B. charAt (0 + I); char list = B. charAt (B. length ()-1-i); if (first! = List) {System. out. print ("not the number of replies"); break;} else if (first = list & I = (B. length ()/2-1) {System. out. print ("number of replies ");}}}

5. Recursion

It is also a simple small code and recursion. To commemorate the past and bless new people.

public class Dg{    public int g(int d){        if(d==1){            return d;        }else{            return d*g(d-1);        }    }}

public class Test {    public static void main(String[] args){        Dg d = new Dg();        System.out.print(d.g(6));    }}
