What is the output and why???

Question

class A

{
public static void main(String args[])
{
int x;
x = 5;
{
int y = 6;
System.out.print(x +""+y);
}
System.out.println(x +""+y);
}
}

Answer 1

An error will be thrown, bcz of scope of variables, scope of variable is valid only in a block (braces), you declared y in a block,. So it's scope/validation will only be in this block, you can not use this y outside of that block, so it will throw an error.
