int[] anArray = { 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 }; Here the length of the array is determined by the number of values provided between braces and separated by commas. You can also declare an array of arrays (also known as amultidimensionalarray) by using two...
官方说明如下：A serializable class can declare its own serialVersionUID explicitly by declaring a field named "serialVersionUID" that must be static, final, and of type long;如果想显式指定 serialVersionUID ，则需要在类中使用 static 和 final 关键字来修饰一个 long 类型的变量，变量名字必须为 "...
Any interface can be functional interface, not merely those that come with Java. To declare your intention that an interface is functional, use the@FunctionalInterfaceannotation. Although not necessary, it will cause a compilation error if your interface does not satisfy the requirements (ie. one ...
