Default Constructor in Java It’s not required to always provide a constructor implementation in the class code. If we don’t provide a constructor, then java provides default constructor implementation for us to use. Let’s look at a simple program where default constructor is being used since...

这一段代码好像看上去没啥问题吧,编译之后给的错是 由于Apple中没有显式的定义构造方法,所以,Apple的默认构造方法被调用了,因为Apple是Fruit的子类,Apple隐式构造函数第一句将执行super(),于是乎去调用Fruit的构造函数,但是Fruit类没有无参构造函数,调用出错。
So this is what constructor chaining is all about. Identify the output of the program and state the reason for your answer. class InterviewBit{ void InterviewBit(){ System.out.println(" Java Constructor interview questions by InterviewBit"); } int InterviewBit(int val){ System.out.println("...
Keep it simple: Constructors should generally be used for setting initial state. Avoid complex logic in constructors. Use constructor chaining: If you have multiple constructors, you can usethis()to call one constructor from another. This helps reduce code duplication. ...
