butYes,you can make a nested class static in Java. In fact, it is even advised (see Effective Java) to prefer anested static classin Java to normal inner classes. Now, the question comes what is a top-level class,
I've learned putfield and putstatic instructions are instance of FieldInsnNode class in ASM, and I want to inject some code to construct a Field object at runtime and call other methods taking this Field object as an argument. I did some experiment by compiling a simple ...

The package org.opentdk.api.application is used to implement base classes that can be inherited by the classes created for a new non-GUI java applications. In the current stage there is only a dispatcher class EBaseSettings that shows how to setup application settings that will be connected ...
Fine-grained specification of time-out delays, because a large portion of the classes found in the java.util.concurrent packages exhibit support for time-out delays. An example is an executor that interrupts tasks execution if the tasks cannot be completed within a bounded timespan. Rich synchr...

static void method1(){ int x = 2; } static void method2(){ System.out.println("Here is the value of x: " + x); } method2() is referring to the x that is used in method1(). But x is local. But x is also static implicitly (I think), which means that there is one copy...
