关于component:关于类的加载和static变量及方法和构造器运行
public class Demo2 { public static int k=0;public static Demo2 t1=new Demo2("t1");public static Demo2 t2=new Demo2("t2");public static int i=print("i");public static int j=print("j");public static int n=99;//代码块{ print("构造函数");}//动态代码块static{ print("动态代码块"); }//静态方法public static int print(String s){ System.out.println(" i= " + i + " " + s + " k= " + k + " n= " + n + " j = " + j); ++i; ++k; ++n; return i;}//结构器public Demo2(String string){ print(string);} //主函数public static void main(String[] args){ Demo2 d=new Demo2 d=new Demo2("T");}} ...
