Import doesn't work

JVM cannot access custom classes when using * in import statement.
My classpath is export CLASSPATH =.: / Home / aksharaaaa / Documents / programs / core_java / class_java:

I first created the Employee.java file as a package, i.e.,.

package com.durgasoft.core;

public class Employee
{

    int eid;
    String ename;
    double esal;

    public Employee(int eid1, String ename1, double esal1)
    {
        eid=eid1;
        ename=ename1;
        esal=esal1;
    }
    public void getEmployeeDetails()
    {
        System.out.println("Employee Details");
        System.out.println("-------------------");
        System.out.println("Eno:"+eid);
        System.out.println("Ename:"+ename);
        System.out.println("ESalary"+esal);
    }
}

      

To compile this file I used the following command: "javac -d .. Employee.java" then the com / durgasoft / core / Employee.class file was created in the class_java folder.
then i created a file test.java in class_java folder with only the following code.

import com.durgasoft.core.*;

public class test{

    public static void main(String[] args){

        Employee e= new Employee(111, "viay", 3333.333);
        e.getEmployeeDetails();
    }
}  

      

when i compile the test.java file then the JVM raises the following error

<b>test.java:5: error: constructor Employee in class Employee cannot be applied to given types;
Employee e= new Employee(111, "viay", 3333.333);  
             ^  
required: no arguments  
found: int,String,double  
reason: actual and formal argument lists differ in length  
test.java:6: error: cannot find symbol  
e.getEmployeeDetails();
         ^  
symbol:  method getEmployeeDetails()  
location: variable e of type Employee 2 errors  

      

If I use a fully qualified name, that is, import com.durgasoft.core.Employee; in the test.java file then JVM can compile and run ...

It looks like you are taking another class from your class. I can happen and it's confusing. I've been in this situation several times and usually JWhich can help. It tells you which class you are using exactly. You can use a utility or source code. It's so small and easy - I always use it in my projects and codebase and use it to disambiguate.
