JAVA BASIC QUESTION

Question

class abc
double a;
System.out.println("hello");
BUT THE SAME FOLLOWING CODE GIVES COMPILATION ERROR:
class abc
double a;
System.out.println("Hello");
---------------------------------------------

Answer 1

Apart from the declaration of instance variables, all other lines of code have to be contained within a method, constructor or a static block. Your code makes use of a static block.
public class Test {
    System.out.println("This is a static block");
  public static void main(String[] args) {
    new Test();
}
