Hi Friend,

Try the following code:

import java.util.*;

class  CountNumberOccurrence {
  public static void main(String[] args) throws Exception{
  int array[]={2,4,2,5,2,4,3,4,5,2};
  for(int counter =0;counter<array.length;counter++){
  int n= array[counter];
  int count=0;
  for ( int i=0; i<array.length; i++){
  if (n==array[i])
  count++;
}
boolean flag=false;
for(int j=counter-1;j>=0;j--){
if(n==array[j])
flag=true;
}
if(!flag){
System.out.println(n+" - "+count+" times ");
}
}
}
}

Thanks
