Currently I have two classes. A Classroom class and a School class. I would like to write a method in the School class public void showClassRoomDetails which would find the classroom details by only using the teacherName.

e.g. teacherName = Daniel className = Science

teacherName = Bob className = Maths

so when I input Bob, it would print out Bob and Maths

many, thanks

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;
}
}





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;
}

public void addTeacherToClassRoom(int classroomId, String TeacherName)
{
    if (classroomId < classrooms.size() ) {
        classrooms.get(classroomId).setTeacherName(TeacherName);
    }
}

public void showClassRoomDetails
{
    //loop
   System.out.println(returnClassRoomName);
   System.out.println(returnTeacherName);     
}
}
