To provide controlled access to an object's data, often instance variables.

To encapsulate data and maintain privacy for certain variables.

When an object is printed directly using System.out.println().

The same type as the instance variable it returns.

Yes, even though they are private, they can be accessed directly within the class's methods.

It immediately exits the current method and returns control to the caller.

It indicates that a method is intended to replace a method with the same signature in a superclass.

The practice of hiding internal data and implementation details of an object from outside access, and only exposing a controlled interface.

It promotes data integrity, reduces dependencies, and allows for easier modification of internal implementation without affecting external code.

Returning a primitive type returns a copy of the value. Returning an object reference returns a copy of the reference, not a copy of the object.

A method that allows clients to access the data of an object.

An accessor method used to get the value of a specific instance variable.

A method that returns information about an object as a string.

Objects, classes, and users that access the data of an object.

Indicates that a method is overriding a method in a superclass.

Returning a copy of the value of a primitive data type.

A copy of the reference to the object is returned, not a copy of the object itself.

The program immediately returns to the point after whatever called the method.

public

To allow other clients (objects, classes, and users) to access the data of an object.

1. Determine the instance variable to access. 2. Define a public method with the return type matching the variable's type. 3. Use a return statement to return the variable's value.

1. Use the @Override annotation. 2. Construct a string representation of the object's state using string concatenation. 3. Return the constructed string.

1. The object's toString() method is automatically called. 2. The toString() method returns a string. 3. The string is printed to the console.

1. Create an instance of the class containing the getter method. 2. Call the getter method on the object using the dot operator. 3. Store or use the returned value.

1. The program executes the code within the getter method. 2. The getter method returns a copy of the value of the instance variable. 3. The program continues execution from where the getter method was called.

1. The method's execution is immediately terminated. 2. The specified value is returned to the calling method. 3. Execution resumes in the calling method at the point immediately following the method call.

1. Allocate memory for the new object. 2. Execute the constructor code, initializing instance variables. 3. Return a reference to the newly created object.

1. Use the object's reference followed by the dot operator. 2. Specify the method name and any required arguments within parentheses. 3. The method is executed using the object's data.

1. The program jumps to the beginning of the called method. 2. The code inside the method is executed. 3. Once the method finishes, the program returns to the point where the method was called.

1. The private variable is directly accessed by its name within a method of the class. 2. No special syntax is required, as access is implicitly granted within the class scope.
