當我們使用開源的CSS檔案時，常會碰到CSS檔案內程式碼排列在一行。本文程式碼就是為了解決這個問題，將一行的CSS檔案轉換為格式優美的檔案。

程式如下，語言Java：

package test;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;

public class CssProcess {
    public
 
 static void main(String[] args) {
        File input = new File("C:\\Users\\lenovo\\Desktop\\input.txt");
        File output = new File("C:\\Users\\lenovo\\Desktop\\output.txt");
        InputStreamReader reader;
        OutputStreamWriter writer;
        try {
            reader = new InputStreamReader(new
 
 FileInputStream(input));
            writer = new OutputStreamWriter(new FileOutputStream(output));
            boolean flag=false;
            boolean flag1=false;
            int tempchar;
            while ((tempchar = reader.read()) != -1) {
                if(tempchar!='\r') {
                    if
 
(tempchar==',') {
                        writer.write(tempchar);
                        if(!flag) {
                            writer.write("\r\n");
                        }
                    }else if(tempchar=='{') {
                        if(flag) {
                            flag1=true;
                        }
                        writer.write(tempchar);
                        writer.write("\r\n");
                        flag=true;

                            writer.write('\t');
                        }
                    }else if(tempchar=='}'){
                        if(flag1) {
                            flag1=false;
                            writer.write("\r\n");
                            writer.write('\t');
                            writer.write(tempchar);
                            writer.write("\r\n");

                            flag=false;
                        }
                    }else if(tempchar==';'){
                        writer.write(tempchar);
                        writer.write("\r\n");
                        if(flag) {

            writer.close();
        } catch (Exception e) {
