Hi Friend,

Try the following code:

import java.util.*;
class ShowData implements Comparable{
String n;
int match;
int run;
int avg;


public void setN(String n){
this.n=n;
}
public String getN(){
return n;
}

public void setMatch(int match){
this.match=match;
}
public int getMatch(){
return match;
}

public void setRun(int run){
this.run=run;
}
public int getRun(){
return run;
}

public void setAvg(int avg){
this.avg=avg;
}
public int getAvg(){
return avg;
}
public int compareTo(Object Player) throws ClassCastException {
if (!(Player instanceof ShowData))
throw new ClassCastException("Error");
int averageRuns = ((ShowData) Player).getAvg();
return this.avg - averageRuns;
}
}
public class BubbleSort{

public static void main(String[]args){
ShowData data[]=new ShowData[5];

Scanner input=new Scanner(System.in);
System.out.println("*****Cricketer Details*****");
int average=0;
int counter=0;
for(int i=0;i<5;i++){
System.out.println("Enter cricketer name: ");
String name=input.next();
System.out.println("Enter number of matches: ");
int matches=input.nextInt();
System.out.println("Enter runs: ");
int runs=input.nextInt();
average=runs/matches;
data[i] = new ShowData();
data[i].setN(name);
data[i].setMatch(matches);
data[i].setRun(runs);
data[i].setAvg(average);
}
for(int i=0;i<5;i++){
ShowData show = data[i];
String name = show.getN();
int matches = show.getMatch();
int runs = show.getRun();
int avg = show.getAvg();
System.out.println(name + " " + matches + " " + runs+" " +avg);
}
Arrays.sort(data, Collections.reverseOrder());
System.out.println("********Sorted In Descending Order by Average********");

for (int i=0; i<5; i++) {
ShowData show = data[i];
String name = show.getN();
int matches = show.getMatch();
int runs = show.getRun();
int avg = show.getAvg();
System.out.println(name + " " + matches + " " + runs+" " +avg);
}
}
}

Thanks
