Suppose I write

Class Test {
int x;
x=7;
int x2=5;
...//some other stuff
}

and

Class Test {
int x;
{
x=7;
int x2=5;
}
...//some other stuff
}

Is there any difference between the two?

The difference is in the scope of the variable x2. The variable x2 is declared inside the block, so it only exists from the point that it is declared until the closing } of the block.

Thanks a lot.
[And I thought - how can two such {} put somewhere like this make a difference]
 
It is sorta covered in the JavaRanch Style Guide.
