Method overriding in java
Download as DOCX, PDF1 like1,691 views
This Java program demonstrates method overriding. It defines a wallet class with dimensions and a salary method that returns 0. Monthly and annual classes extend wallet, overriding the salary method to return the product of the dimensions, and printing the appropriate salary text. The main method creates instances of each class, assigns them to a wallet reference variable, and calls salary to print the results.
