Hi,
Looking for an example, where couple separate classes in separate files will
be attached and used (executed) in new class in separate file.

Thanks in advance!!!

Looking for an example, where couple separate classes in
separate files will be attached and used (executed) in new
class in separate file.

// *** Separate Package ***

javac xx/A.java
javac xy/B.java
javac xz/UseAndB.java
java xz.UseAndB

// File: A.java
package xx;
public class A { public void doA() {}}

// File: B.java
package xy;
public class B { public void doB() {}}

// File: UseAandB.java
package xz;
import xx.A;
import xy.B;

public class UseAandB
{
public static void main(String[] args)
{
A a = new A(); a.doA();
B b = new B(); a.doB();
}
}

// *** Same Package ***

javac xp/UseAndB.java
java xp.UseAndB

// File: A.java
package xp;
public class A { public void doA() {}}

// File: B.java
package xp;
public class B { public void doB() {}}

// File: UseAandB.java
package xp;
public class UseAandB
{
public static void main(String[] args)
{
A a = new A(); a.doA();
B b = new B(); b.doB();
}
}

I hope this helps.
