String array initialization with constant values

[Marcel Wentink]

What is exactly the difference between:

String[][] valuesa = {{""}};
and:
String[][] valuesb = new java.lang.String[][]{new java.lang.String[]{""}};

or is it just the same may-be?

[Himalay Majumdar]

Both are same:

public static void main(String[] args) {

		String[][] valuesa = {{"c"}}; 
		String[][] valuesb = new java.lang.String[][]{new java.lang.String[]{"c"}}; 

		System.out.println("-->"+valuesa.length);
		System.out.println("-->"+valuesb.length);

		System.out.println("-->"+valuesa[0][0].length());
		System.out.println("-->"+valuesb[0][0].length());	
	}

The above code produces 1,1,1,1.

Both are double dimenson arrays, elements of double dimension arrays are nothing but ..one dimenson array.

String[][] valuesb = new String[][]{new String[]{""}}; is anonymous 2 dimensional array creation

For exam ..I think just remembering the syntax of anonoymous 1d will be good enough..

its like

String[] valuec = new String[]{new String("")};

String[] varName = {};

That implicitly creates an array. I just read that in the JLS 3.0.

But Ryan that would create a zero length array and the code in this question will create a one length array...
