从方法创建的类实例重写嵌套类的方法

// 外部类
public class OuterClass {
    private int outerValue = 10;

    // 嵌套类
    public class InnerClass {
        public void display() {
            System.out.println("Outer value: " + outerValue);
        }
    }

    // 创建嵌套类实例并重写方法
    public void createAndOverride() {
        InnerClass inner = new InnerClass() {
            @Override
            public void display() {
                System.out.println("Overridden display method");
            }
        };
        inner.display(); // 输出: Overridden display method
    }

    public static void main(String[] args) {
        OuterClass outer = new OuterClass();
        outer.createAndOverride();
    }
}

public class OuterClass {
    private static int outerValue = 10;

    public static class InnerClass {
        public void display() {
            System.out.println("Outer value: " + outerValue);
        }
    }

    public static void main(String[] args) {
        InnerClass inner = new InnerClass() {
            @Override
            public void display() {
                System.out.println("Overridden display method");
            }
        };
        inner.display(); // 输出: Overridden display method
    }
}
