Obj1.setHiddenX(20);
Obj1.exposed = 200;
System.out.println("hidden is"+" "+obj1.getHiddenX()+" "+"exposed="+" "+obj1.exposed();

class SS{
private int hiddenX; // Encapsulated
public int exposed; // Not encapsulated
public void setHiddenX(int newValueX)
{
hiddenX = newValueX + 5;
}
public int getHiddenX() {
hiddenX = hiddenX + 5;
return hiddenX;
}
}

Answer 1

- start a new object with the new keyword

SS obj1 = new SS();

- Obj1 and obj1 are different objects, java is case sensitive so you always need to write the variable name exactly the same

- the print statement is a bit messy and hard to read
You can try storing the values to make shorter, easier to read statements

int hid = obj1.getHiddenX();
int exVar = obj1.exposed;
int exMet = obj1.exposed();

System.out.print("hidden is " + hid +".");
System.out.print("exposed = " + exMet + ".");

Mistakes that are easy enough to debug.

Just read the error messages and it shows which line is wrong and what is wrong.

I cleaned it up so the code runs but I had to implement the exposed() method otherwise it wouldn't run.

Answer 2

1. obj1 is not the same as Obj1
2. SS() must be new SS()
3. exposed is not a method is a property
4. you must close the parenthesis for the println
