ps:Java 修饰符

Java语言提供了很多修饰符,主要分为以下两类:

  • 访问修饰符
  • 非访问修饰符

修饰符用来定义类、方法或者变量,通常放在语句的最前端。我们通过下面的例子来说明:

public class className { // ...}private boolean myFlag;static final double weeks = 9.5;protected static final int BOXWIDTH = 42;public static void main(String[] arguments) { // 方法体}

访问控制修饰符

Java中,可以使用访问控制符来保护对类、变量、方法和构造方法的访问。Java 支持 4 种不同的访问权限。

  • default (即缺省,什么也不写): 在同一包内可见,不使用任何修饰符。使用对象:类、接口、变量、方法。
  • private : 在同一类内可见。使用对象:变量、方法。 注意:不能修饰类(外部类)
  • public : 对所有类可见。使用对象:类、接口、变量、方法
  • protected : 对同一包内的类和所有子类可见。使用对象:变量、方法。 注意:不能修饰类(外部类)。
