Nonaccess Member Modifiers

We have already discussing about the access member, which is signifies to code can be invoke the method one class to another class. here we can use to the some there looks like : 
  1. transient
  2. synchronized
  3. native
  4. strictfp

But preferably we are using static.in this function first at modifiers applied to methods, we are using modifiers applied to instance variable.
