变量,你可以声明一个static块,Static 块仅在该类被加载时执行一次。下面的例子显示的类有一个static方法,一些static变量,以及一个static 初始化块: // Demonstrate static variables,methods,and blocks. class UseStatic { static int a = 3; static int b; static void meth(int x) { System.out.println("...
333.Static inner classes 静态内部类:静态内部类是内部类最简单的形式,它于一般的类很相似,除了被定义在了某个类的内部。 334.Static methods 静态方法:静态方法声明一个方法属于整个类,即它可以不需要实例化一个类就可以通过类直接访问之。 335.Static variable 静态变量:也可以称作类变量。它类似于静态方法,也是...
publicclassVariableExample{staticfloatPI=3.14f;//2 - Class variable} A variable declared as“public static”can be treated as global variable in java. 4.3. Local Variables These are used inside methods as temporary variables exist during the method execution. The syntax for declaring a local vari...
