java静态变量和final关键字

public class StaticVariable {

    public static int num1=20;
    
    public void TestAdd()
    {
        int num2=88,result;
        
        result=num1+num2;
        System.out.println(result);
    }
    
    public static void StaMethod()
    {
        System.out.println("老子是静态方法");
    }
    
    public static void main(String[] args)
    {
        StaticVariable obj=new StaticVariable();
        obj.TestAdd();
        StaMethod();
    }
}

父类

public  class FinalTest {

    public final double P=3.14159295;
    
     final void Test1()
    {
        System.out.println("我是Test1");
    }
    
    public void Test2()
    {
        System.out.println("我是Test2");
    }
    
}

子类

public class SubFinal extends FinalTest {

    @Override
    public void Test1()                      #编译不通过
    {
        System.out.println("造反了");
    }
    
    @Override
    public void Test2()
    {
        System.out.println("起义，还等什么");
    }
    
    public static void main(String[] args)
    {
        SubFinal obj=new SubFinal();

    }
    
}
