Simple problem

can someone explain me why i cant compile this
class k{

String[][] first = new String[1][3];

first[0][0]= "p";

}

You did not define a main() in your class.
it should be

Code:

---

class k
{
 public static void main(String[] myArgs)
  {

      String[][] first = new String[1][3];

      first[0][0]= "p";
  {
}

---

All Programs need a starting position. In Java The Main() method is that starting position. Once I added that into your program I was able to compile and run the code.

Your explanation is not related to compilation.

The first line is okay since it is a declaration statement, so the compiler will not complain about it. However, the second line is an assignment and it needs to be declared in some method or a static code block, failing which you get a compilation error.

This is the actual code

class j
{


String[][] first = new String[1][3];
first[0][0]= "p";
void method(){
System.out.println(first[0][0]);

}
}


class k{
public static void main(String[] args){

j one = new j();
System.out.println(one.method());

}
}

and it says identifier expected.

A method must have an identifier...public, private, protected
