Currently I have two classes. a classroom class and a School class. I would like to write a method in the School class to call public void setTeacherName(String newTeacherName) from the classroom class.
classroom.java
public class classroom { private String classRoomName; private String teacherName; public void setClassRoomName(String newClassRoomName) { classRoomName = newClassRoomName; } public String returnClassRoomName() { return classRoomName; } public void setTeacherName(String newTeacherName) { teacherName = newTeacherName; } public String returnTeacherName() { return teacherName; }
}School.java
import java.util.ArrayList;
public class School { private ArrayList<classroom> classrooms; private String classRoomName; private String teacherName; public School() { classrooms = new ArrayList<classroom>(); } public void addClassRoom(classroom newClassRoom, String theClassRoomName) { classrooms.add(newClassRoom); classRoomName = theClassRoomName; } // how to write a method to add a teacher to the classroom by using the // classroom parameter // and the teachers name

You should capitalize names of your classes. After doing that do this in your school class,
Classroom cls = new Classroom();
cls.setTeacherName(newTeacherName);Also I'd recommend you use some kind of IDE such as eclipse, which can help you with your code for instance generate getters and setters for you. Ex: right click Source -> Generate getters and setters
2Try this :
public void addTeacherToClassRoom(classroom myClassRoom, String TeacherName)
{ myClassRoom.setTeacherName(TeacherName);
}class A{ public void methodA(){ new B().methodB(); //or B.methodB1(); }
}
class B{ //instance method public void methodB(){ } //static method public static void methodB1(){ }
}in School,
public void addTeacherName(classroom classroom, String teacherName) { classroom.setTeacherName(teacherName);
}BTW, use Pascal Case for class names. Also, I would suggest a Map<String, classroom> to map a classroom name to a classroom.
Then, if you use my suggestion, this would work
public void addTeacherName(String className, String teacherName) { classrooms.get(className).setTeacherName(teacherName);
}Instead of using this in your current class setClassRoomName("aClassName"); you have to use classroom.setClassRoomName("aClassName");
You have to add the class' and at a point like
yourClassNameWhereTheMethodIs.theMethodsName();I know it's a really late answer but if someone starts learning Java and randomly sees this post he knows what to do.
