I am using one .java file and i have given a package name as com.onlinmebank but netbeans displaying error at this package declaration line as Incorrect Package.
Following is the package declaration code.
package com.onlinebank;
import java.sql.*;
import java.util.*;
public class BankCommons{
//All Code Here
}
Can Anybody tell me why i am getting this error
All Java keywords are lower-case!
So, this should work:
package com.onlinebank;
import java.sql.*;
import java.util.*;
public class BankCommons {
//All Code Here
}
And keep in mind, that the file BankCommons.java must be placed in the directory com/onlinebank.
In package, p should be small not Package(no captial P).
Also in public class p should be small. Similarily for Import also.
Important note all java keywords are in lower cases

I have this class that I want to import into another class that is outside the previous class folder.
So, I have a GoogleDriveAPI class, which I want to import to DocumentServices class.
on top of my GoogleDriveAPI class there is this line
package org.ofbiz.ClientManagementServices;
but when I try to import it to DocumentServices class with this line below
import org.ofbiz.clientmanagementservices.GoogleDriveAPI;
I get this error below,
error: package org.ofbiz.clientmanagementservices does not exist
[javac17] import org.ofbiz.clientmanagementservices.GoogleDriveAPI;
What might be the problem with my import because I am 100% sure I am doing the right thing?
Java packages are cas sensitive.
You should change the import to :
import org.ofbiz.ClientManagementServices.GoogleDriveAPI;
I am working on a somewhat large project with many subdirectories. I am, however, coming across an issue of importing classes from within another directory. The directory structure is as so:
main.dir
repository.dir
Bill.java
transaction.dir
AutomaticBillPay.java
How can I import Bill into AutomaticBillPay?
I have tried may iterations of:
package main;
package main.repositorysys;
import main.repositorysys.Bill;
import repositorysys.Bill;
import Bill;
Sadly, the only line that compiles is the first: package main;. Any tips / direction will help!
You can achieve it through this
/*Declare your class package */
package main.transactionsubsys;
/*import the classes you want */
import main.repositorysys.Bill;
/*Write your class*/
public class AutomaticBillPay {
/*AutomaticBillPay code */
}
Your AutomaticBillPay should look like this:
package main.transaction;
import main.repository.Bill;
public class AutomaticBillPay {
// your class implementation here
}
Not sure where repositorysys came from?
package should be the full path to your encompassing directory
import should be the full path to the class you want to import
Here's the code for the source file:
package moa4;
public class Book {
....
}
And for the destination file:
import moa4.Book;
public class Library {
...
}
The source and the destination are both saved in the same directory with the address:
C:\Users\\java\M\moa4
I'm getting the following error: package moa4 does not exist
You asked Library to import a package moa4.Book but you defined no such package. Instead, you defined a type Book inside package moa4, and that is not consistent with your import directive.
You could either import the package, or make that an import static of the class, but since Book and Library are both in the same package you don't need the import directive at all.
As mentioned, C:/Users/java/M needs to be in your classpath ("-cp" option).
I am new in using eclipse java using multiple .java files. My eclipse java project consist of one project file two package files, each with one .java class
My 2nd java class import the 1st java class/package, like so
VerifyLogin.java
package VerifyLogin;
import ArgumentCountException;
ArgumentCountException.java
// ...
The problem is VerifyLogin.java is getting an error
Import ArgumentCountException cannot be resolved
Or any reference I have to ArgumentCountException cannot be resolved to a type.
In java if you need to import a class then you need to use the full qualified name for that class, as the following:
import packageName.YourClass;
For Example, if your need to use Scanner class, then you need to import it as:
import java.util.Scanner;
But if the class was withing the same package, you don't need to import it.
When importing your class, it should be done as below:
//Current package name for the VerifyLogin Class (All package names should be lowercase by convention)
package packageforcurrentclass;
//Import statements: import thedependencyclasspackage.thedependencyclassname
import exceptionpackage.ArgumentCountException;
public class VerifyLogin
{
...
}
I am trying trying to import java.lang.Math in Java on Eclipse and am getting the error in the title. Here is the beginning of my code:
import java.lang.Math;
package test1;
This error is popping up under "package test1;"
The package statement must be first in the file, before anything, even imports:
package hw1;
import java.lang.Math;
Plus, you don't need to import java.lang.Math, or anything in java.lang for that matter.
The JLS, Chapter 7 says:
A compilation unit automatically has access to all types declared in
its package and also automatically imports all of the public types
declared in the predefined package java.lang.
Place the package declaration before the import statement
package hw1;
import java.lang.Math;
The import statement itself is unnecesary as all classes in java.lang are imported by default.
