Two D array

[Joshua Ebarvia]

How come did b became a 2D array?

int[] a = null, b[] = null
a = b;
System.out.println(a);

  Sample.java:5: incompatible types
found   : int[][]
required: int[]
		a = b;	
		    ^

Because of the [] immediately after the int. Your code is the same as this:

int[] a = null;
int[] b[] = null;
// ...

In Java, you can put the [] either after the type or after the variable name, or you can even mix them (as happens with b above). There are historical reasons for this, Java inherited part of its syntax from C and C++.
