Can anyone let me know, what is the cause for the exception type

org.hibernate.MappingException: No Dialect mapping for JDBC type: -1

The entire stack trace is given below:

Hi Gitesh,

You are invoking a static method in an initializer block, though the compiler won't complain, but the interpreter simply ignores it, it seems.

Try the following code,

class tt { String s = "-"; public static void main(String[] args) { //go(); System.out.println(new tt().s); } { System.out.println("hi"); go(); }//line a //static { go(); } void go() { s+= "s"; } }

Here the method is not static, so we can't invoke it from static initializer block, but we can invoke with an initializer block.

Hope this helps.

Praveen.

Hi Sugantha,

Your understanding of order of execution is correct for static blocks, init blocks and constuctors.

Since the x in static block is belonging to that block only, i.e., local to that block. So no compilation error occurs with conflict to static int x.

Next you asked for the explanation for getting the output. Here it follows:
static variables x and y are initialized to 0 by default.

In the main method x-- makes it -1.
Then in myMethod x is post incremented so the equation for
y=x++ + ++x will be y=(-1)+(0+1) here x is -1, x++ will be 0 and then ++x will be 1, so y will be 0.

Thereafter in SOP the result printed will be 3.

I don't think so.

The intent of these certifications is to test your subject skills, but not to test your power of memory.

If it the case then what would be the difference between schools kids and professionals

So, don't bother about it.

Good Luck
