Either via a constructor...
public class Sample {}
public class In1 {
Sample inst1 = new Sample();
In2 inst2 = new In2( inst1);
}
public class In2 {
Sample mySample;
public In2( Sample s) {
this.mySample = s;
}
public void doSomethingWithSample() {
mySample.doSomething();
}
}
... or as parameter of a method:
public class Sample {}
public class In1 {
Sample inst1 = new Sample();
In2 inst2 = new In2();
inst2.doSomethingWithSample( inst1);
}
public class In2 {
public void doSomethingWithSample(Sample s) {
s.doSomething();
}
}
The choice of whether you use a constructor or a method depends on the amount of time that In2 needs to remember the Sample. If the In2 class need to access it often, make Sample a member, and use the cunstructor.
