什么是所需值的含义？据我理解，您指的是更改超类的值。
希望这段代码能帮助您。
class A0 {int f;A0(int f) {this.f = f;}}class A1 extends A0 {int f = 0;A1(int f) {super(f);this.f = f;}}class B extends A1 {int f = 0;B(int f) {super(f);System.out.println(super.f);this.f = f;}int getFofA() {return f;}}public class question {public static void main(String[] arg) {B b0 = new B(5);System.out.println(b0.getFofA());}}
英文:
What do you meaning by needed value? As I understand it, you mean changing the value of the super class.
I hope this code will help you.
class A0 {int f;A0(int f) {this.f = f;}}class A1 extends A0 {int f = 0;A1(int f) {super(f);this.f=f;}}class B extends A1 {int f = 0;B(int f) {super(f);System.out.println(super.f);this.f=f;}int getFofA() {return f;}}public class question {public static void main(String[] arg) {B b0 = new B(5);System.out.println(b0.getFofA());}}
