java - 无法使用Java中的参数化构造方法实例化对象

Question

这是我要实例化的类(class):

public class GoogleSheetsAPI {

String spreadsheetId;
Sheets service;
String credentialsFile;

public void GoogleSheetsAPI() {
}

public void GoogleSheetsAPI(String spreadsheetId, String credentialsFile) throws Exception {
    this.spreadsheetId = spreadsheetId;
    this.credentialsFile = credentialsFile;
    service = getSheetsService();
}

}

这就是我创建类 GoogleSheetsAPI的对象的方式

GoogleSheetsAPI googleSheetsAPI = new GoogleSheetsAPI(spreadsheetId, credentiialsFile);

Answer 1

构造函数不得具有void，应为:

public GoogleSheetsAPI(String spreadsheetId, String credentialsFile) throws Exception {
    this.spreadsheetId = spreadsheetId;
    this.credentialsFile = credentialsFile;
    service = getSheetsService();
}
