How to pass and return objects in Java?
Date:2023-01-07
Passing and returning objects in Java works the same way as passing and returning other values. When a method needs an object as an argument, the object reference can be passed as the argument — the same as primitives. When a method needs to return an object reference, it can just return the reference to the desired object.
For example, if you have a class called Employee and you want to pass and return an Employee object in a method, you can do it like this:
// Pass an employee object to a method
public void setEmployee(Employee emp){
// do something with the employee
}
// Return an Employee object from a method
public Employee getEmployee(){
// create a new Employee object
Employee emp = new Employee();
// return the object
return emp;
}
