occurs. It is not invoked when an object loses scope, for instance. Consequently, it
is unpredictable when, or even if, finalize() will be executed.

(ii) Finalize() method Chapter Five: Object oriented programming with Java

Program Example 5.22:
FOR ONLINE READING ONLY
Java program to demonstrate finalize()method

public class MyHome {
private int value;
// Constructor
public MyHome(int value) {
this.value = value;
System.out.println(“Object created with value: “ + value);
}
// Destructor-like method
protected void finalize() {
// Cleanup actions
System.out.println(“Object with value “ + value + “ destroyed!”);
}
public static void main(String[] args) {
// Create objects
MyHome obj1 = new MyHome(15);
MyHome obj2 = new MyHome(25);
// Several operations continues
// This set objects 1 and 2 to be null to make it eligible for garbage collection
obj1 = null;
obj2 = null;
// This line of code is going to set garbage collection
System.gc(); // This cod explicitly request garbage collection
System.out.println(“End of program”);
}
}
