Hi All,
I have one doubt regarding Java.
I have 2 packages in java. In that i have imported one package into another
as follows.

Java

package package1;
public class Base1{
public void Method1(){
System.out.println("Method1");
}
}

package package2;
import package1;
public class Base2{
public void Method2(){
System.out.println("Method2");
Base1 b1=new Base1();
b1.Method1();
}
}


import package2;
public class clsMain{
public static void main(String[] args){
Base2 b2=new Base2();
b2.Method2();
}
}

Can any body tell me this
its showing some errors as follows
while compiling the second file Base2 the following error is coming

Base2.java:2: '.' expect
import Package1;

and While compiling the clsMain file its showing following errors

clsMain.java:1: package package2 does not exist
import package.*;
^
.\Base21.java:2: '.' expected
import Package1;
             ^
Use.java:9: cannot access Base2
bad class file: .\Base2.java
file does not contain class Base2
Please remove or make sure it appears in
th.
                Base2 m = new Base2();

If anything wrong is there in this can you give code for this scenario please

You don't import packages. You import classes in a package.

So the form is one of the following (brackets used to indicate a name not syntax.)

Java

import {package}.*;
import {package}.{class name in package};

So you would use

Java

import Package1.*;

Also note that for future questions it helps to specify the files in which your code is in.

There are 2 ways in order to use the public classes stored in package.
a) Declare the fully-qualified class name
...

Java

world.HelloWorld helloWorld = new world.HelloWorld();
world.moon.HelloMoon helloMoon = new world.moon.HelloMoon();
String holeName = helloMoon.getHoleName();

b) Use an "import" keyword

Java

import world.*;  // we can call any public classes inside the world package
import world.moon.*;  // we can call any public classes inside the world.moon package
import java.util.*;  // import all public classes from java.util package
