Java's Constructors

Constructors are made to create objects and initialize their values. Unlike other methods, constructor method carries the name of its class and does not return any value.

I have two programs below with one file containing the constructor while the  other one is calling the constructor file.

[+/-] show/hide



public class TestExpandedConstructor {
public static void main (String args[]){

EventSiteConstructor oneSite = new EventSiteConstructor(); // calling file with constructor



System.out.println("Name :"+oneSite.getManagerName());
System.out.println("Site Number: "+oneSite.getSiteNumber());
System.out.println("Usage Fee:"+oneSite.getUsageFee());
}
}


public class EventSiteConstructor {

private int siteNumber;
private double usageFee;
private String managerName;

EventSiteConstructor(){  //this is the constructor method
siteNumber=5;
usageFee=1000.00;
managerName="Rosilie";
}

public int getSiteNumber()
{ return siteNumber;}

public void setSiteNumber(int n)
{ siteNumber=n;}

public void setUsageFee(double amt)
{ usageFee=amt;}

public double getUsageFee()
{ return usageFee;}
public String getManagerName()
{ return managerName;}

public void setManagerName(String name)
{ managerName=name;}

}
