Question

inheritance, classes, instance methods, constructors

A cash processing company has a class called Account used to process transactions:

Account objects interact with Transaction objects, which have many methods including:

The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to process it. Your class should have a single constructor that accepts a parameter of type Client, and it should include the following method:

Assume that all transactions enter the system by a call on the process method described above.

Explanation / Answer

added percentFiltered class and also included constructor and method which returns double value 0.00 to 100.00. please have a look

.....

public class Account {
public boolean __processCalled;
  
public Account(Client c) {//account constructor
__processCalled = false;
}
  
public boolean process(Transaction t) {//method process which returns value between -100 to 1000000
__processCalled = true;
return t.value() > -100 && t.value() < 1000000;
}
  
public class Client {}
  
public class Transaction {
private int value;
  
public Transaction(int v) {//transaction constructor
value = v;
}
  
public int value() {//method to return value
return value;
}
}
public class FilteredAccount {//filteredAccount constructor
private double value;
public FilteredAccount(Client c) { //FilteredAccount constructor
__processCalled = false;
}
public double percentFiltered(Transaction t){ //method percentFiltered returns double value
if(__processCalled==false){ // transaction occurs
return t.value() > 0.0 && t.value() < 100.00;
}
return 0.0; //if no trnasition occurs
}
}
}
