6. What is Java Bean
• It is a reusable Software component.
• A bean encapsulate many object into
one object.
• We can access this object from
multiple places.
• It provides easy maintenance.
• It provide methods to set and get the
values of the properties, known as
getter and setter methods.

7. Creation of Java bean

8. Generating Getters and Setters

11. Setting values for it’s
properties
import com.baabte.exambean;
import java.util.ArrayList;
public class ques {
ArrayList <exambean> ques = new ArrayList<exambean>();
Public int questn(){
exambean qs1 = new exambean();
qs1.setQuestion("1. Who give music to the song Sare jahan se acha..?");
qs1.setA("A.Pandit Ravi Shankar");
qs1.setB("B.Subha lakshmi");
qs1.setC("C.AR Rahman");
qs1.setD("D.Muhammad Iqbal");
qs1.setAnswer("A");
ques.add(qs1);
}

12. Getting values for it’s properties
public static void main(String[] args) {
int count=0;
boolean flag=false;
ques quesObj = new ques();
ArrayList newList = quesObj.getList();
int size = newList.size();
for(int i=0;i<size;i++)
{
do
{
else if(!answer.matches("A") && !answer.matches("B")
&& !answer.matches("C") && !answer.matches("D")
)
{flag=true;
System.out.println("Invalid Entry");
flag=false;
exambean beanObj=(exambean) newList.get(i);
System.out.println(beanObj.getQuestion());
System.out.println(beanObj.getA());
System.out.println(beanObj.getB());
System.out.println(beanObj.getC());
System.out.println(beanObj.getD());
System.out.println("Pleas Enter Your Answer: ");
Scanner ans = new Scanner(System.in);
String answer= ans.nextLine().toUpperCase();
if(answer.matches(beanObj.getAnswer())){
count++;
}
}
}
}
}
while(flag);}
System.out.println("Total Score= "+count);
