Declaration and Access Control
Determine output:class A{{System.out.print("b1 ");}public A(){System.out.print("b2 ");}}class B extends A{static{System.out.print("r1 ");}public B(){System.out.print("r2 ");}{System.out.print("r3 ");}static{System.out.print("r4 ");}}public class Test extends B{public static void main(String[] args){System.out.print("pre ");new Test();System.out.println("post ");}}

r1 r4 pre b1 b2 post r3 r2
r1 r4 pre b1 b2 post
Compilation fail
pre r1 r4 b1 b2 r2 r3 post

Declaration and Access Control
Choose all the lines which if inserted independently instead of "//insert code here" will allow the following code to compile:public class Test{ public static void main(String args[]){ add(); add(1);add(1, 2); }// insert code here}

static void add(int...args){}
static void add(int[]... args){}
static void add(int args...){}
void add(Integer... args){}
static void add(int... args, int y){}

Declaration and Access Control
Determine output:public class InitDemo{static int i = demo();static{ System.out.print(i); }InitDemo(){System.out.print("hello1");}public static void main(String... args){ System.out.print("Hello2");} static int demo(){ System.out.print("InsideDemo");return 10;}}

IllegalArgumentException is thrown at runtime.
Compilation error.
InsideDemo 10 Hello2
Hello2 InsideDemo 10
InsideDemo 10 Hello2 hello1
