Java程序的执行顺序

package ExecuteOrder;

class A {
    public A() {
        System.out.print("Class A here\n");
    }

    {
        System.out.print("block here\n");
    }

    static {
        System.out.print("static block A here\n");
    }
}

public class ExecuteOrder extends A {

    public ExecuteOrder() {
        // TODO Auto-generated constructor stub
        System.out.print("Class B here\n");
    }

    {
        System.out.print("block here\n");
    }

    static {
        System.out.print("static block B here\n");
    }

    // 1. 静态语句块最先被执行
    // 2. 执行块语句
    // 3. 执行构造函数[先父类再子类]
    public static void main(String[] args) {
        System.out.print("main begin\n");
        new ExecuteOrder();
        System.out.print("main end\n");
    }
}

//output
static block A here
static block B here
main begin
block here
Class A here
block here
Class B here
main end
