thanks for the answer .......but why should the variable definition has to be in the method.Because statements have to be in method.
You can initialize variables and as part of the declaration, but you cannot make separate assignments.
public class MyClass{
  int i = 4;  //this is fine and preferred by many.
  Integer j;  //this declaration if fine, but the object has not been initialize yet and will complain if you do not do so in the constructor.
  int k;     //this is also fine and as an atomic value--will be initialize to 0.
  Integer p = new Integer(55); //correct declaration and initialization
  k = 3;   //this is an assignment statement, not part of a declaration and will err out.
  MyClass(){
    j = new Integer(2);  //this initializes the object appropriately.
