Discussion Forum : Operators and Assignments - Finding the output (Q.No. 2)
2.
What will be the output of the program?
class Test
{
public static void main(String [] args)
{
Test p = new Test();
p.start();
}
void start()
{
boolean b1 = false;
boolean b2 = fix(b1);
System.out.println(b1 + " " + b2);
}
boolean fix(boolean b1)
{
b1 = true;
return b1;
}
}
Answer: Option
Explanation:
The boolean b1 in the fix() method is a different boolean than the b1 in the start() method. The b1 in the start() method is not updated by the fix() method.

Priya: the variable after start() is assigned to be false.
Here many b1s here & there makes confusion. b1 which is the parametre of fix()is entirley different from previous one.

But my question is java won't support pass by reference how can a reference variable pass to a method effect an original array?
I also have the same doubt. Please clarify clearly.

Even it is declared as boolean in fix(),it is defined as an ordinary variable.so it couldn't reflect the value in start(). Got it guys

I have a doubt between both, I didn't understand the notion of reference object, while the result isn't true?

@All.
How both boolean are different if both have the same name?
fix(boolean b1){
b1=true
return b1
}
