Question
Advanced Java Programming with Object-Oriented Programming Design
VERY IMPORTANT NOTE, PLEASE READ BEFORE ANSWERING THE QUESTION BELOW!!: Because I'm in an advanced Java class that must use Object-Oriented Programming Design in all assignments, the answer for the question below MUST contain private variables, least 2 CLASSES, accessors and mutators for the private variables. You can use any other additional other object-oriented design (OOD) concepts if you want to but private variables, least 2 CLASSES, accessors and mutators for the private variables are a must! I've seen answers to the question below already posted, however they don't utilize object-oriented design (OOD) concepts such as a private variables, least 2 CLASSES, accessors and mutators for the private variables etc, which is required for this advanced Java programming class. So please answer the question meet the requirements for this question. Basically, I need advanced Java object-oriented design concepts for simple programs so here's to hoping this works out and if it does, I'll give a thumbs up, I promise!!!
Question:(Constructor Failure) Write a program that shows a constructor passing information about constructor failure to an exception handler. Define class SomeClass, which throws an Exception in the constructor. Your program should try to create an object of type SomeClass and catch the exception that’s thrown from the constructor.
Explanation / Answer
SomeClass.java
public class SomeClass{
private int a;
private String b;
public int getA() {
return a;
}
public void setA(int a) {
this.a = a;
}
public String getB() {
return b;
}
public void setB(String b) {
this.b = b;
}
public SomeClass(int a, String b) throws Exception{
if(a == 0 || b.equals(""))
throw new Exception("Null Exception");
this.a = a;
this.b = b;
}
@Override
public String toString() {
return "SomeClass [a=" + a + ", b=" + b + "]";
}
}
Driver.java
public class Driver {
public static void main(String[] args){
SomeClass sc;
try {
sc = new SomeClass(0, "Hello world");
System.out.println(sc);
} catch (Exception e) {
e.printStackTrace();
}
}
}
