How do invoke a method which you have created in the previous class created to another class you just created in java

Question

calling method in a class to another class

Answer 1

If the method is static, you can use
className.methodName
to access method for that class in your current class.

Example -
class A{
public static void hello() {
System.out.println("hello");
}
}

class TestClass {
public static void main(String args[] ) throws Exception {
A.hello();
}
}

If the method is not static, you need to create the object of that class in the current class and then use the method using the below syntax -
ThatClass thatClassObject = new ThatClass();
thatClassObject.methodName();

class A{
public void hello() {
System.out.println("hello");
}
}

class TestClass {
public static void main(String args[] ) throws Exception {
A a = new A();
a.hello();
}
}

Answer 2

1. declare that method as public.

2. Create an instance of that class
---------------------------------------------------
Student aStudent = new Student();
---------------------------------------------------

3. Call the method through the object
---------------------------------------------------
aStudent.GetName();
---------------------------------------------------

---------------------------------------------------
If the method is static
---------------------------------------------------

Student.GetTotalStudentCount();
