Question

write java code by inheritance with collage class type and add all necessary things like getter and setter method,override,calling,

Answer 1

```java

class College {
private String collegeName;

public College() {
this.collegeName = "Unknown";
}

public College(String collegeName) {
this.collegeName = collegeName;
}

public String getCollegeName() {
return collegeName;
}

public void setCollegeName(String collegeName) {
this.collegeName = collegeName;
}

public void displayInfo() {
System.out.println("College Name: " + collegeName);
}
}

class Student extends College {
private String studentName;

public Student(String collegeName, String studentName) {
super(collegeName);
this.studentName = studentName;
}

public String getStudentName() {
return studentName;
}

public void setStudentName(String studentName) {
this.studentName = studentName;
}

@Override
public void displayInfo() {
super.displayInfo();
System.out.println("Student Name: " + studentName);
}
}

public class Main {
public static void main(String[] args) {
Student student = new Student("ABC College", "John Doe");
student.displayInfo();

student.setCollegeName("XYZ College");
System.out.println("Updated College Name: " + student.getCollegeName());
}
}
```

In this code, the `College` class has a private field `collegeName` with getter and setter methods. The `Student` class extends the `College` class and has an additional private field `studentName` with corresponding getter and setter methods. The `displayInfo` method is overridden to display both college and student information. The `main` method creates a `Student` object, calls `displayInfo` to show the initial information, and updates the college name using the setter method.
