java - 什么是初始化所有这些的更干净、更优雅的方法？

Question

我正在一一命名所有这些。有没有占用更少空间的方法？

public class Matt{
    PImage matt, 
    imgLS1, imgLS2, imgLS3, imgRS1, imgRS2, imgRS3,
    imgLSB1, imgLSB2, imgLSB3, imgRSB1, imgRSB2, imgRSB3,
    imgLW1, imgLW2, imgLW3, imgRW1, imgRW2, imgRW3,
    imgLWB1, imgLWB2, imgLWB3, imgRWB1, imgRWB2, imgRWB3;
    public Matt(){    
        imgLS1  = loadImage("./Images/Matt/MattLS1.png");
        imgLS2  = loadImage("./Images/Matt/MattLS2.png");
        imgLS3  = loadImage("./Images/Matt/MattLS3.png");
        imgRS1  = loadImage("./Images/Matt/MattRS1.png");
        imgRS2  = loadImage("./Images/Matt/MattRS2.png");
        imgRS3  = loadImage("./Images/Matt/MattRS3.png");
        imgLSB1 = loadImage("./Images/Matt/MattLSB1.png");
        imgLSB2 = loadImage("./Images/Matt/MattLSB2.png");
        imgLSB3 = loadImage("./Images/Matt/MattLSB3.png");
        imgRSB1 = loadImage("./Images/Matt/MattRSB1.png");
        imgRSB2 = loadImage("./Images/Matt/MattRSB2.png");
        imgRSB3 = loadImage("./Images/Matt/MattRSB3.png");
        imgLW1  = loadImage("./Images/Matt/MattLW1.png");
        imgLW2  = loadImage("./Images/Matt/MattLW2.png");
        imgLW3  = loadImage("./Images/Matt/MattLW3.png");
        imgRW1  = loadImage("./Images/Matt/MattRW1.png");
        imgRW2  = loadImage("./Images/Matt/MattRW2.png");
        imgRW3  = loadImage("./Images/Matt/MattRW3.png");
        imgLWB1 = loadImage("./Images/Matt/MattLWB1.png");
        imgLWB2 = loadImage("./Images/Matt/MattLWB2.png");
        imgLWB3 = loadImage("./Images/Matt/MattLWB3.png");
        imgRWB1 = loadImage("./Images/Matt/MattRWB1.png");
        imgRWB2 = loadImage("./Images/Matt/MattRWB2.png");
        imgRWB3 = loadImage("./Images/Matt/MattRWB3.png");
    }
}

将您的图像放在 Map<String,PImage> 中, 按图像后缀组织 map 。就访问图像而言，这种方法可能不如直接使用变量方便/高效，但它会为您节省很多空间:

static final String[] suffixes = new String[] {"LS1", "LS2", "LS3", ..., "RWB3"};
Map<String,PImage> images = new HashMap<String,PImage>();
public Matt() {
    for (String suffix : suffixes) {
        PImage image = loadImage("./Images/Matt/Matt"+suffix+".png");
        images.put(suffix, image);
    }
}
