. "Netstat-a" is mainly used to check which listening ports are open on the local computer. As shown in 1, port 7626 appears in the listening port. We can preliminarily conclude that, this computer may have been implanted with Ice Horse. 2.

is the method of reloading, and the other is the method of coverage.Polymorphic polymorphic and Object polymorphism (multiple forms of an object).The premise of polymorphism: Consider a subclass object as a parent object,Embodied in the code is animal a=new Bird (...);All polymorphism can be attributed to two theorems:1. You can look at the object as a parent class object, once you have done so, you can only invoke the original defined properties and methods in the parent class.That is, a metho

null key. , but when HashMap is treated as collection (the values () method returns collection), its iterator operation time overhead is proportional to the capacity of HashMap. Therefore, if the performance of the iterative operation is quite important, do not set the initialization capacity of the hashmap too high or load factor too low.Weakhashmap classWeakhashmap is an improved hashmap, which implements a "weak reference" to key, which can be recycled by GC if a key is no longer referenced

the superclass is an inner class, and the constructor method of the inner class cannot be called automatically, so it is necessary to explicitly call the constructor method of the superclass in the constructor method of the subclass. Next Example: Class C extends A.b {C () {New A (). super (); This sentence implements a call to the inner class construction method.}} The construction method can also be written like this: C (a A) {A.super ();}//Use this

1. Why do I overwrite the run () method?The thread class is used to describe threads. The class defines a function that stores the code that the thread wants to run, and the function of the store is implemented by the run () method.2. The running state of the thread:The thread is created, the start () method is called to enter the running state, and if the call to sleep (time) or the Wait () method thread enters a frozen state, but still exists, you can try the Notify () method to wake the threa
