What is obvious is the customer class doesn't have a field 'i' so trying to use l.i isn't going to work. What were you trying to do?


Sir , What is obvious is you answer carelessly .

Code:
class calculate {
private  int profitRate=20;
public long i,j;

public void CalculatedMoneyAmount(customer obj){ 
i=( obj.getmoney() +( obj.getmoney())/100);
 
System.out.println( "i = " + i );

  }
Good luck friend!
