Okay, new B gets first an A get created, first instance fields, then calling B’s init() which sets i and j to 100. Then the B gets created, which initializes the i to 0. Enter construct A… Enter B’s init… 0 100 3 solved Do not debug or run in jvm,can you tell me what’s … Read more
What algorithms are used? Java uses TLAB (Thread Local Allocation Buffers) for “normal” sized objects. This means each thread grab some Eden space and turns this grab of memory into individual objects. Thus small objects are typically sequential in memory for that thread, except if a new chunk of memory needs to be grabbed. Large … Read more

You can use some obfuscation tools, like ProGuard. A self written ClassLoader, must be placed in a standard .class file, that the JVM can load it. And then you secure loader can be reverse engineered. Don’t do it by yourself. Writing “secure” code without knowing cryptographic algorithms will lead to error-prone an insecure code 5 … Read more
Is there a way to make JVM act normal so that it wouldn’t require a -Xmx option, and would allocate and free memory directly from the OS just as any normal application would? That is what it does by default. You only need to set the maximum heap size to indicate at what point you … Read more
