Simple Java program 6

6. Simple Java programs to know what 
    output  will be.


class aaa
{
final private int a;
private int b;
public void sam()
{ 
System.out.println(a); 
}
aaa()
{
a=7;
}
aaa(int e)
{
b=e;
}
}

class psp
{
public static void main(String aa[])
{
aaa x;
x=new aaa();
x.aaa();

}
} 


O/P:- Error will generate because x is not assigned in parameterized constructor.
