  • 对象实例化、JVM 装载过程了解
public class InstanceInitTest {        {         a=6;   //为什么可以省略 int 修饰符     }      int a=9;   public static void main(String[] args)   {          System.out.println(new InstanceInitTest().a);   }}

同理

public class FinalErrorTest {       final int age;    {       //    System.out.println(age);        printAge();        age  =6;        System.out.println(age);    }    public void printAge()    {           System.out.println(age);    }    public static void main(String[] args) {           new FinalErrorTest();    }}																输出		0																		6
