Anonymous Array

[Bindesh Vijayan]

The code :

[B]
class C {
static void print(Object v[][]) {
for(int i=0;i<v.length;i++)
System.out.println(v[i]);
}
public static void main(String [] a) {
print( {new Object(),new Object(),new Object()},
{"A1","A2","A3","A4"}
);//1
}
}
[/B]

When executed gets the following error:

Array constants can only be used in initializers.
print( {new Object(),new Object(),new Object()},
Array constants can only be used in initializers.
{"A1","A2","A3","A4"}

Am iam not using an initializer.JLS has the following statement

[B]
An array initializer is written as a comma-separated list of 
expressions, enclosed by braces "{" and "}".
[/B]

Pls. help..
Thanks

Try run the code like this:

class C {
   static void print(Object v[][]) {
      for(int i = 0; i < v.length; i++) {
         for(int j = 0; j < v[i].length; j++) {
            System.out.println(v[i][j]);
         }
      }
   }
   public static void main(String [] a) {
      Object o[][] = {{new Object(),new Object(),new Object()},{"A1","A2","A3","A4"}};
      print(o);
   }
}

I modify your code:

class C {
static void print(Object v[][]) {
for(int i=0;i<v.length;i++)
System.out.println(v[i]);
}
public static void main(String [] a) {
print( new Object[][]{{new Object(),new Object(),new Object()},
{"A1","A2","A3","A4"}}
);
}
}

Anonymous array used like this:new int[]{1, 2, 3}
or new int[10].

Guys,
First things first, Thanks, and a correction I have missed some parts of the code as Rene points out.All I can say is it happens sometimes.
And yes coming back to the problem,I knew this that the array should be given with new
operator,thats not what I wanted to know ,but the specification provided by JLS .
An array initializer is written as a comma-separated list of expressions, enclosed by braces "{" and "}".

I want to be cleared on that...
Thanks

This initialize an one dimension array:

String str[] = {"One", "Two"};

This initialize a two dimension array:

String str[][] = {{"One", "Two"},
                  {"One", "Two"}};
