初学者如何学习Java？
学习基础知识
与任何事情一样，了解Java的基础知识是最好的开始。这是你可以直接开始的事情–在线学习基础知识对启动你的Java编程有很大帮助。像许多事情一样，开始时可能会有点不知所措。如果你是一个完全的初学者，代码可能看起来像胡言乱语。但请记住，每个人的起点都是一样的。如果你能坚持下去，你就能做到! 这里有一个很好的资源供初学者查看。
练习编码
用一句老生常谈的话来说，实践出真知。如果你不想学习或练习，你就不会成为一个成功的Java程序员。幸运的是，你可以在家里练习Java编程，而不需要任何花哨的软件或设施，所以最好的办法是在你掌握了基础知识后就开始。你如何开始呢？
研究算法
这里是你要考验自己的地方。为了能够设置你的算法，你需要能够理解Java的基础知识。在你练习Java的早期，你会为自己创造并解决一个问题–这都是学习曲线的一部分。当你告诉你的计算机如何准确地做你想让它做的事情时，算法就会发挥作用。在真正设定你的算法之前，先试着进行一些练习。
定期阅读有关Java编程的资料
阅读有关Java编程的资料，就像你现在所做的那样，只会让你受益。当然，你的大部分资料都可以在网上找到。你会在看似非常棒的网站上得到真正最新的、定期检查的资料。无论你是Java的学生，还是自学成才的Java专家，或者仅仅是Java爱好者，网上的资源对你来说都是无价之宝。
加入一些论坛（比如这个）也是一个好主意，在那里你可以和其他Java程序员讨论任何让你困惑的问题，或者仅仅是聊一聊你有多喜欢Java。

下面是我们Java代考成功案例：
- Which of the following statements about Java and C++ objects is FALSE?
a) In Java, heap-based objects are created using the new keyword.
b) In Java, stack-based objects are created when an object variable is declared.
c) In C++, heap-based objects are created using the new keyword.
d) In C++, stack-based objects are created when an object variable is declared.
e) In both Java and C++, heap-based objects are necessary for the dynamic aspects of Object Oriented
Programming.
- Which of the following statements about method replacement in a class hierarchy is FALSE?
a) In Java, a child method overrides an abstract method with the same signature in the parent class.
b) In C++, a child method overrides a virtual method with the same signature in the parent class.
c) In Java, a child method shadows a non-abstract method with the same signature in the parent class.
d) In C++, a child method shadows a non-virtual method with the same signature in the parent class.
e) In ruby, a child method overrides a method with the same signature in the parent class.
以下关于类的层次结构中的方法替换的说法哪个是错误的？
a) 在Java中，一个子方法覆盖了父类中具有相同签名的抽象方法。
b) 在C++中，一个子方法覆盖父类中具有相同签名的虚拟方法。
c) 在Java中，一个子方法影射父类中具有相同签名的非抽象方法。
d) 在C++中，一个子方法影射父类中具有相同签名的非虚拟方法。
e) 在Ruby中，一个子方法覆盖了父类中具有相同签名的方法。
- If a method in a child class has the same name as one in the parent class, but a different signature, this
type of replacement is called…
a) Shadowing.
b) Overriding.
c) Abstraction.
d) Refinement.
e) Redefinition. - Which of the following statements about Java interfaces is FALSE?
a) Classes that implement an interface are related as derived classes of that interface.
b) A given class may implement as many interfaces as desired.
c) Methods declared in an interface are always public.
d) An interface may be used to declare constant values. - Which of the following statements about ruby variables is FALSE?
a) All variables are implemented as pointers.
b) The type of a variable is determined by whatever it currently points to.
c) Instance variables must begin with the character ‘@’.
d) Instance variables must be declared with a type in the initializer - In ruby, overloading of methods in the same class…
a) is not possible. The first method definition in the class is used.
b) is possible, as long as the methods have different parameter lists.
c) is not possible. The last method definition in the class is used.
d) is possible, as long as the methods have different return values. - Consider the following ruby statement:
attr_reader :item
Which of the following statements is TRUE?
a) It defines a local variable called item.
b) It defines an instance variable called @item.
c) It defines the instance variable @item and an accessor method.
d) It defines an accessor method for the symbol item but not an instance variable. - Which of the following statements about ruby initializers is FALSE?
a) They are invoked when a new instance of a class is created.
b) They are typically where instance variables are created.
c) An initializer may accept an array as a parameter.
d) A class may have only one initializer.
e) In a subclass initializer, the superclass initializer is called automatically.
