final int x = 1; // x = 2; // cannot assign value to final variable 'x' final A y = new A(); y.a = 1; 2. 方法 声明方法不能被子类重写。 private 方法隐式地被指定为 final,如果在子类中定义的方法和基类中的一个 private 方法签名相同,此时子类的方法不是重写基类方法,而是在子类中...
What is static blank final variable in Java - No. It is not allowed in Java. Compiler will fail the compilation throwing error that the blank final field may not have been initialized.
When you combinestaticfinalkeywords in Java you create a variable that is global to the class and impossible to change.

答:final 可以修饰属性、方法、类、局部变量(方法中的变量),修饰属性的初始化可以在编译期,也可以在运行期【此测试没有通过,有待商榷】,初始化后不能被改变;修饰的属性表明是一个常数;修饰方法表示方法不能在子类中被重写;修饰类表示类不能被继承。 final String attribute;//Variable 'attribute' might not ha...
