What is printed?

public static void main(String[] args)

int i = 6;

aMeth(i);

System.out.print(i);

public static void aMeth(int i)

System.out.print(i);

i = i + 1;

System.out.print(i);

2)

What is printed as the value of b?

 Scanner kybd = new Scanner(System.in);

 System.out.println("Enter two ints " );

 int i = kybd.nextInt();

 int j = kybd.nextInt();

 boolean b = ((i % 2) == 0) && ((j % 2) == 0);

 System.out.println(b);

Expert Solution

Ans=>

1) What is printed?

The output will be 6 7 6

As first variable int i is initialize to value 6 => int i = 6.

Then it is passed to function Meth(int i)where it is first printed as 6.

Then in function meth i is incremented by 1 and again got printed as 7.

=>i = i + 1;

After which control returns back to main function and again prints i value as 6.

Here value of i in the main function will be equal to 6 and not 7 because its scope was only limited to that particular function. Hence output will be 6 7 6.

2) What is printed as the value of b?

The value of b depends on the input I & j from the user.

The statement (i % 2) == 0) =>returns true if remainder is zero after dividing value i by 2.

The outputs for corresponding inputs are as follows:

I	J	output
Even	Even	True
Even	Odd	False
Odd	Even	False
Odd	Odd	False
