请注释一下下面的代码谢谢

Question

public void update(String path){
        try {
            Workbook book = Workbook.getWorkbook(new File(path));
            Sheet sheet = book.getSheet(0);
            for(int i=1;i<sheet.getRows();i++){
                String id = sheet.getCell(0, i).getContents().trim();
                String word = sheet.getCell(1, i).getContents().trim();
                String level = sheet.getCell(2, i).getContents().trim();
                String cixing = sheet.getCell(3, i).getContents().trim();
                System.out.println(id+","+word+","+level+","+cixing);
                HSKWordLevel wordLevel = this.manager.getHskWordLevelById(NumberUtils.createInteger(id)+8822);
                if(wordLevel != null){
                    wordLevel.setCixing(cixing);
                    this.manager.updateHskWordLevel(wordLevel);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
请注释一下，最好把用到的类说明一下，谢谢

public void update(String path){ 
        try { 
            Workbook book = Workbook.getWorkbook(new File(path)); //打開path下的Excel文件
            Sheet sheet = book.getSheet(0); //定位第一個sheet頁
            for(int i=1;i <sheet.getRows();i++){ //按行數循環
                String id = sheet.getCell(0, i).getContents().trim(); //取得第一行第二列内容去空格
                String word = sheet.getCell(1, i).getContents().trim(); //...
                String level = sheet.getCell(2, i).getContents().trim(); //...
                String cixing = sheet.getCell(3, i).getContents().trim(); //...
                System.out.println(id+","+word+","+level+","+cixing); //打印所取得内容
                HSKWordLevel wordLevel = this.manager.getHskWordLevelById(NumberUtils.createInteger(id)+8822); //找到WordLevel為“id+8822”内容
                if(wordLevel != null){ 
                    wordLevel.setCixing(cixing); //將cixing寫入此HSKWordLevel對象中
                    this.manager.updateHskWordLevel(wordLevel); //更新此對象
                } 
            } 
        } catch (Exception e) { 
            e.printStackTrace(); 
        } 
    }
