Exercise 13 (one array)

A bunch of people
 PackageCN.CH.W; Public classPersonarray { Public Static voidMain (String args[]) {person per[]=NewPerson[3]; per[0]=NewPerson ("straw mushroom", 20); per[1]=NewPerson ("mushroom", 22); per[2]=NewPerson ("Pleurotus ostreatus", 23);  for(intx=0;x<per.length;x++) {per[x].getinfo (); }        }}

 PackageCN.CH.W; Public classPerson {PrivateString name; Private intAge ;  PublicPerson (String name,intAge ) {         This. name=name;  This. age=Age ; }     Public voidGetInfo () {System.out.println ("Name:" + This. name+ "Age:" + This. Age); }}

One array

 PackageCN.CH.W; Public classA { Public voidGetfibonacci (intNumber ) {        intNleft = 0; intNright = 1;        System.out.print (Nright);  for(inti = 0; I < number; i++) {        intsum = Nleft +Nright; System.out.print (" " +sum); Nleft=Nright; Nright=sum; }        }         Public Static voidMain (string[] args) {NewA (). Getfibonacci (10); }}

Selection method

 PackageCN.CH.W; Public classA { Public Static voidMain (string[] args) {int[] arr={23,234,3,1,19,21,231,88,90,11};  for(inti=0;i<arr.length-1;i++) {             for(intj=i+1;j<10;j++) {                if(arr[i]>Arr[j]) {                    inttemp; Temp=Arr[i]; Arr[i]=Arr[j]; ARR[J]=temp; }            }        }          for(inti=0;i<arr.length;i++) {System.out.println (arr[i]); }     }}

Bubble

 PackageCN.CH.W; Public classA { Public Static intMain (string[] args) {int[] arr={23,234,3,1,19,21,231,88,90,11};  for(inti=0;i<10;i++) {             for(intj=0;j<10-1-i;j++) {                if(arr[j]>arr[j+1]) {                    inttemp; Temp=Arr[j]; ARR[J]=arr[j+1]; Arr[j+1]=temp; }            }        }         for(inti=0;i<arr.length;i++) {System.out.println (arr[i]); }        return0; }}
