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
Try 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.
