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);

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

True

Odd
False
