使用方法清理代码

Question

我已经创建了一个三菱标志生成器，如下所示。它从logo.txt文件中获取输入，并使用这些ints/chars创建在logo.txt文件中标识的徽标。我只是觉得我的代码非常重复，我想把它整理成单独的方法，而不是一遍又一遍地重复，有什么建议如何清理它吗？我将非常感谢任何和所有的反馈。或者仅仅是一个起点。提前谢谢你。

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

    try {
        input = new Scanner(new FileInputStream("config.txt"));
        //initialize ithe variable's input and output
    } catch (FileNotFoundException e) {
        System.out.println("File not found.");
        System.exit(0);

    }

    int size = Integer.parseInt(inputStream.nextLine());
    int numLogos = Integer.parseInt(inputStream.nextLine());
    char letter1 =  inputStream.next().charAt(0);
    char letter2 =  inputStream.next().charAt(0); 

    for(int bee = numLogos; bee > 0; bee--){ 
        for(int y = 0; y < size; y++) { 

            for(int x = 0; x < y; x++) {
                System.out.print(letter2);
            }
            for(int x = 0; x < size - y; x++) {
                System.out.print(letter2);
            }
            for(int x = 0; x < y; x++) {
                System.out.print(letter2);
            }
            for(int x = 0; x < size - y; x++) {

您可以在代码中多次使用以下代码：

        for(int x = 0; x < y; x++) {
            System.out.print(letter2);
        }
        for(int x = 0; x < size - y; x++) {
            System.out.print(letter2);
        }
        for(int x = 0; x < y; x++) {
            System.out.print(letter2);
        }
        for(int x = 0; x < size - y; x++) {
            System.out.print(letter2);
        }

它可以替换为

        for(int x = 0; x < 2*size; x++) {
            System.out.print(letter2);
        }

此外，还有以下内容：

        for(int x = 0; x < size - y; x++) {
            System.out.print(letter1);
        }
        for(int x = 0; x < size - y; x++) {
            System.out.print(letter1);
        }

可以替换为

        for(int x = 0; x < 2*(size - y); x++) {
            System.out.print(letter1);
        }
