Code:

		ArrayList<String> ar = new ArrayList<String>();
		ar.add("abc");
		ar.add("def");
		ar.add("ghi");
		ar.add("jkl");
		
		// error handling, if the array size of not even.
		if (ar.size() % 2 != 0) {
			System.out.println("ArrayList cannot have odd number of values if to be converted to String[][]");
			return;
		}
		
		String[][] ray = new String[ar.size()/2][2];
		
		int c = 0;
		for (int i = 0; i < ar.size(); i = i+2) {
			ray[c][0] = ar.get(i);
			ray[c][1] = ar.get(i+1);
			c++;
		}
