java - 更改与整数对应的输出文件的名称

Question

所以，我目前正在用java制作一个程序，但我想制作该程序，以便它更改与我的类中的整数相对应的文件输出名称:

if(height > 10){

这是我的整个代码

import java.awt.*;

public class imageReader {
    private BufferedImage img, imageOut;
    private int imageHeight, imageWidth;
    private int deepbkg;
    public imageReader() {

        initializeSet();
        readImage();
        ProcessImage();
        createOutImage();
        saveProcFile(); 
    }

    public static void main(String[] args) {
        @SuppressWarnings("unused")
        imageReader iR= new imageReader();
    }

    public void initializeSet() {
        Color cold = new Color(250, 100, 200);
        deepbkg = cold.getRGB();
    }

    public  void readImage(){
        try{
            img = ImageIO.read(new File("C:\\Users\\David_tmp\\Desktop\\ProjectImages\\LongIslandforPrint.jpg"));
        }
        catch (IOException e) {         
        }
    }

    public void ProcessImage(){
        imageHeight = img.getHeight();
        imageWidth = img.getWidth();
        System.out.println(imageHeight+ "  "+imageWidth );
    }

    public void createOutImage(){
        imageOut = new BufferedImage(imageWidth, imageHeight, 1);
        for (int imageX = 0; imageX < imageWidth; imageX++) {
            for (int imageY = 0; imageY < imageHeight; imageY++){
                int redbluevalue = img.getRGB(imageX, imageY);
                double height = getHeight(redbluevalue);
                // *****IMAGE HEIGHT****
                if(height > 10){
                    //***END OF HEIGHT****  

                    imageOut.setRGB(imageX, imageY, redbluevalue);
                }
                else{
                    imageOut.setRGB(imageX, imageY, deepbkg);   
                }
            }
        }
    }

    public void saveProcFile() {
        try {
            File outputfile = new      File("C:\\Users\\David_tmp\\Desktop\\ProjectImages\\LongIslandforrrrPrint.jpg");
            ImageIO.write(imageOut, "jpg", outputfile);
        }
        catch(IOException e) {
        }
    }

    public double getHeight(int RGB) {
        double heightX =0.;
        Color tcol = new Color(RGB);
        int Red = tcol.getRed();
        int Blue = tcol.getBlue();
        int Green = tcol.getGreen();
        if( Red >248) {
            heightX = 81.+ 99 * ((double)Red/250.);
        }
        if( Red <= 7 ) {
            if(Green >= 249 ) // using blue  value to calculate height
                 // range 23 -81
            {
                heightX = 23. + 58. *((double)255 - Blue)/255.;
            }
            else               //using green to calculate height
            {
                heightX =   24.* ((double)Green-20.)/230.;  
            }
        }
        return heightX;
    }
}

所以我想要

LongIslandforrrrPrint.jpg

要更改此处的整数:

 if(height > 10){

因此文件输出将根据整数发生变化

所以文件名输出会是这样的

Heightmap[Integer].jpg

类似这样的吗？
