Answer:
Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.
Explanation:
Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.
<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.
Ex:
In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.
<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.
Ex:
In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).

Explanation:
//Define the class.
public class Loan implements java.io.Serializable {
//Define the variables.
private static final long serialVersionUID = 1L;
private double annualInterestRate;
private int numberOfYears;
private double loanAmount;
private java.util.Date loanDate;
//Define the default constructor.
public Loan() {
this(2.5, 1, 1000);
}
//Define the multi argument constructor.
protected Loan(double annualInterestRate, int numberOfYears,
double loanAmount) {
this.annualInterestRate = annualInterestRate;
this.numberOfYears = numberOfYears;
this.loanAmount = loanAmount;
loanDate = new java.util.Date();
}
//Define the getter and setter method.
public double getAnnualInterestRate() {

}

}

}

this.loanAmount = loanAmount;
}
//Define the method to compute the monthly payment.
public double getMonthlyPayment() {
double monthlyInterestRate = annualInterestRate / 1200;
double monthlyPayment = loanAmount * monthlyInterestRate / (1 -
(Math.pow(1 / (1 + monthlyInterestRate), numberOfYears * 12)));
return monthlyPayment;
}
//Define the method to get the total payment.
public double getTotalPayment() {

}
public java.util.Date getLoanDate() {

}
}
//Define the client class.

//Create the loan class object.

//Call the method to compute the results.

tp = obj.getTotalPayment();
//Format the results.
result = "Annual Interest Rate: "+ r+"\n"+
"Number of Years: "+y+"\n"+
"Loan Amount: "+a+"\n"+
"monthlyPayment: "+mp+"\n"+

//Add the result to the textarea.
ta.setText(result);
//Create an object of the server class.
serverLoan = new ServerLoan(this);
});
//Set the scene to the stage.
//Set the stage title.
//Make the scene visible.
primaryStage.setScene(scene);
primaryStage.setTitle("ClientLoan");
primaryStage.show();
}
//Define the main method lauch the application.
public static void main(String args[])
{
launch(args);
}
//Define the server class.

//Define the constructor.

//Initialize the object.

//Add the date and the result to
//the text area.

//Create the grouppane.

//Initialise the stage object.

//Set the scene to the stage.
//Set the stage title.
//Make the scene visible.
subStage.setScene(scene);
subStage.setTitle("ServerLoan");
