What is the result of the following program?

1: public class Egret {
2: private String color;
3: public Egret() {
4: this("white");
5: }
6: public Egret(String color) {
7: color = color;
8: }
9: public static void main(String[] args) {
10: Egret e = new Egret();
11: System.out.println("Color:" + e.color);
12: }
13: }


A. Color:
B. Color:null
C. Color:White
D. Compiler error on line 4.
E. Compiler error on line 10.
F. Compiler error on line 11.

Explanation:
Line 10 calls the constructor on lines 3–5. That constructor calls the other constructor. However, the constructor on lines 6–8 assigns the method parameter to itself, which leaves the color instance variable on line 2 set to its default value of null

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
