Hi paramesh

I think scope of object p in the try block is over when block ends
if u move the println statement next to object creation statement it works

Hi

The compilation error is caused by a problem in the variable scope "p".

p is defined inside the try{} and is not accesible after the "catch".

If you want to use this variable outside the catch you must declare it outside the try:


Param p = null;
try{
p = new Param();
} catch {

}

System.out.println(p.a);
