Java try/catch 类构建参数的错误

Question

我对编码还很陌生，正在开发一个项目，其想法是查看 Excel 电子表格，然后创建一个类，为每行信息构建一个语句。我下面有以下代码。

public class Message {

// information from excel
String excelPath = "./data/RecruiterData.xlsx";
String sheetName = "Sheet1";
ExcelUtils excel = new ExcelUtils(excelPath, sheetName);
int excelRowCount = excel.getRowCount();


// build recruiter class
public static Recruiter[] buildRecruiter = {
    try {
    // this needs to be a for each cell filled in excel, create an instance of recruiter
    for (int i = 0; i < excelRowCount; i++) {
        new Recruiter(excel.getCellData(1, i), excel.getCellData(2, i), excel.getCellData(3, i), excel.getCellData(4, i));
    }
} catch (Exception e) {
    System.out.println("Something went wrong");

   }
}

但它却给了我一堆错误。第一个错误出现在 public static Recruiter[] 中，在该行的末尾，它显示：期望 } 期望。

接下来，我的 try catch 语句有错误，只是说意外的标记。

最后，它为新 Recruiter 行中的每个参数提供一个错误，指出未处理的异常：java.io.IOException。我在网上寻求帮助没有成功，所以我想我会询问一下。太感谢了！

嗯，我认为你的错误是在方法声明中

   public class Message {

// information from excel
static String excelPath = "./data/RecruiterData.xlsx";
static String sheetName = "Sheet1";
static ExcelUtils excel = new ExcelUtils(excelPath, sheetName);
static int excelRowCount = excel.getRowCount();


// build recruiter class
public static Recruiter[] buildRecruiter () {
    //in java methods are declarated for that way [scope] [instance] data_type name ([params]) { [body; return data_type]}
    //next if you declare static your function all fields must be static too or change te method declaration to public or private 
    try {
    // this needs to be a for each cell filled in excel, create an instance of recruiter
    for (int i = 0; i < excelRowCount; i++) {
        new Recruiter(excel.getCellData(1, i), excel.getCellData(2, i), excel.getCellData(3, i), excel.getCellData(4, i));
    }
} catch (Exception e) {
    System.out.println("Something went wrong");

   }
}
}
