Here are some fresh learnings-
1. Using JDeveloper beginner- Great video-
http://jdeveloperzerotopro.com/
2. How to enable input from the keyboard in Jdeveloper-
- Go to project properties(Right Click on the Project),
- click on Run/Debug settings,
- select your Run configuration (Default) and Click Edit.
- Locate "Tool settings" and check "Allow program input" in Additional Runner Options.
- Save settings and run your program again.
- Now you will see under the console input field for your inputs.
On a Java src file, first --> Make and then --> Run.
My first program- tried first on Console & then on JDeveloper-
________________________________________
package learnjavaproject;
public class Learn1 {
public Learn1() {
super();
}
public static void main (String [] args){
System.out.println("hello");
}
}
________________________________________
Then am working now on an App - "PayRoll"
These are the specs of this App-
Base class - Employee. [Properties - First Name, Last name, Base Salary ]
Three extended classes- Software Engineer, Project Leader, Project manager.
Factors affecting salary of these employees-
Software Engineer - skill
Project Leader - No_Team_Members
Project_manager
Project manager
________________________________________
Expected behavior --> By giving a type of employee and the parameter, the salary should be given back.
________________________________________
Employee Class-->
________________________________________
package learnjavaproject;// Project name is LearnJavaProject.
public class Employee {
private String FirstName;
private String LastName;
public Employee() {
super();
}
public Employee(String FirstName, String LastName){
SetFirstName(FirstName);
SetFirstName(LastName);
}
public void SetFirstName(String FirstName){
this.FirstName = FirstName;
}
public void SetLastName(String LastName){
this.LastName = LastName;
}
public String GetFirstName(){
return FirstName;
}
public String GetLastName(){
return LastName;
}
public String FullName(){
return FirstName +" "+LastName;
}
}
________________________________________
And the driver file -
package learnjavaproject;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import learnjavaproject.Employee;
public class PayRoll {
public PayRoll() {
super();
}
public static void main (String [] args) throws Exception{
BufferedReader br = new BufferedReader(
new InputStreamReader(System.in));
String FirstName;
String LastName;
System.out.println("Enter First name: ");
String fName = br.readLine();
System.out.println("Enter last name: ");
String lName = br.readLine();
Employee e = new Employee(fName,lName);
System.out.println(e.GetFirstName());
}
}
________________________________________
But the output is null at this time. Let me try to debug this.. Will write again later...:)
Oh , It was a case Sensitive issue. I had put Firstname instead of FirstName...... OMG, what !!!!!
Now it works, Thanks to Anna who trouble-shooted this.
