如果任何人知道答案，并使用StackOverflow，请问他们awnser这个问题！
这是我的代码：

If anybody knows the answer, and uses StackOverflow, please ask them to awnser this question! Here is my code:

                f.dispose();
                JLabel complete = new JLabel("You are now complete.");
                JFrame f = new JFrame("Complete");
                Container a = f.getContentPane();
                a.setBackground(Selected[0]);
                f.add(complete);
                f.setSize(500,500);
                f.setVisible(true);
                f.setIconImage(img.getImage());
            }
            });
    }
}

P.S：只解决第一个错误！

Any help is appreciated! P.S: Only solve the first error!!! That fixes the others too!!!

推荐答案

尝试在声明中留下数组的大小，并使用花括号代替方括号。如：

try leaving off the size of the array in the declaration and using curly braces instead of square braces. Such as:

Colors = new String[]{"black", "blue", "cyan", "darkGray", "gray", "green", "lightGray", "magenta", "orange", "pink", "red", "white", "yellow"};
