Class Java Super Call Issues Stack Overflow 1 you can't declare variables inside the parameter section of a call to super(); perhaps what you need is: public datedriver(int y, int m, int d) { super(y, m, d); } then when you construct the datedriver object in your main() method, you pass in values for y, m and d. In java, inheritance is a powerful mechanism for reusing and extending functionalities across classes. by leveraging the super keyword, we can access the methods and properties of a parent class from its subclass. however, one limitation in java surprises us: super.super.method () is not allowed.
Class Java Super Call Issues Stack Overflow Super () calls the constructor of the base class. the call to super () must be the first statement in the constructor. if you provide arguments to super (), it will call base class constructor with the corresponding signature. The only way is to call another existing super constructor, e.g super ("rex"); if you had a public animal (string name) constructor . Let's say i have three classes a, b and c. all have a public void foo () method defined. now from c's foo () method i want to invoke a's foo () method (not its parent b's method but the super super class a's method). i tried super.super.foo ();, but it's invalid syntax. how can i achieve this?. 智能推荐 call the method of the super class in an other method of the subclass i already asked about something related to the game i am developing. the problem occured while the developement, but actually it has nothing to do with the game it self. i have a method ('resize' in a.

Gradle 2.8 updates groovy to 2.4. this seems to bring a problem with calling super method. see bundle.groovy which extends the jar task and overrides the copy method. running this on gradle 2.7 works as expected. running on gradle 2.8 leads to a stackoverflow: caused by: java.lang.stackoverflowerror at aqute.bnd.gradle.bundle.copy(bundle.groovy:50). The super keyword in java is a reference variable used inside a subclass to refer to its immediate parent class. it is primarily used to access parent class methods, constructors, and fields that have been overridden or hidden in the child class. java automatically calls the superclass constructor using super () if no explicit call is made, but developers can use it manually for more control. If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword super. you can also use super to refer to a hidden field (although hiding fields is discouraged). Adding a public or protected modifier to the super class solves the problem. here is what i found. in metaclassimpl.methodindexaction#methodnameaction (), if you use a protected modifier in the super class method, the mopmethods list contains the $super method. if the modifier is removed, the method disappears from mopmethods.
