Here we have used two format specifiers,%sand%d, where%sis used for string while%dis used for signed decimal integer. We have also used\n, which inserts a new line at a specific point in the text. publicclassStringPrint{publicstaticvoidmain(String[]args){String str="The color of this ...
printStackTrace(); } } } 注意:基于序列化和反序列化实现的克隆不仅仅是深度克隆,更重要的是通过泛型限定,可以检查出要克隆的对象是否支持序列化,这项检查是编译器完成的,不是在运行时抛出异常,这种是方案明显优于使用Object类的clone方法克隆对象。让问题在编译的时候暴露出来总是好过把问题留到运行时。 63. ...

Part 3 of our series on Java printing introduces you to the print framework, as Jean-Pierre Dubé explains its design and the functionality that it will offer. Working on top of the Java Print API, the framework will make printing pages much easier by pr
此方法将导致对 printComponent、printBorder 和printChildren 的调用。如果目的是定制打印外观的方式,建议重写前面提及的方法之一,而不是此方法。但是,如果想在调用超类行为之前准备好状态,则重写此方法很有用。例如,如果想在打印前更改组件的背景颜色,则可以执行以下操作: public void print(Graphics g) { Color ...
