java inner class example

are freed, but the object allocated in the heap is not reclaimed, and the local variable lincintf in the main method points to it ;There's no problem here, but in line 27th, lincintf calls the test method, and the test method accesses the local variable A in the member method Localinclassre, and a does not exist at this time, so an error occurs;That is, local variables are different from the life cycle of the objects of local inner classes;To solve t

The Java inner class is divided into 4 sections, namely, overview, member inner class, local inner class, and anonymous inner class.In this

?? We all know that in Java you can use an inner class to place the definition of a class inside the definition of another class, which is an inner class, but the anonymous

the name of the inner class is superfluous, soThe anonymous inner class is used.3, how to implement anonymous internal class? The implementation of an anonymous inner class is very si

The inner class of the member means that the bread in an outer class has a non-static class, for example:class outerclass{ // variables, function definitions ... class innerclass { // variable, function definition ... }}

The Java inner class is divided into 4 sections, namely, overview, member inner class, local inner class, and anonymous inner class.In this

One.Continue to deepen the previous example. Now we're going to tell you that the inner class can be placed locally in addition to the member. In other words, that's where you can put it.Where does the local position refer to?Continue with the completion of the program as follows:The above actually confessed the internal clas
