Java Masterclass | Beginner to OOP Programming with Eclipse

Explore how Java methods work as single-line calls that change values, using equalsIgnoreCase as an example. Learn the syntax—variable, dot, method name, and parentheses—and prepare for the first method, toUpperCase.

Explore the Java toUpperCase method by building a simple Eclipse project named upper case test, reading user input via a dialog, converting the string to uppercase, and printing the result.

Learn boolean variables and the Character.isLetter method in Java, using a char input and if statements to determine if a character is a letter, with a practical demonstration.

Master the isDigit method in Java to test whether a character is a digit, with a program that prints 'it is a number' or 'it is not a number'.

Discover how the isWhitespace method from the character class helps identify spaces and whitespace characters, enabling word counting and string scanning in Java.

The length method measures characters in a string, returns an integer, and stores it for use in validating user input, such as enforcing a six-character password.

The lecture demonstrates the compareTo method by comparing lowercase strings using ASCII values, showing negative, zero, and positive results, and using these results to alphabetize names.

Builds a Java Eclipse project that collects first name, last name, and age, validates age above 18, converts names to uppercase, sorts by surname, and prints initials with age.

Develop a Java program in Eclipse that collects two names and ages, handles garbage input, enforces age over 18 with loops, alphabetizes entries, and prints a formatted result.

Explore essential methods from section 1 of the advanced Java programming course with Eclipse to build bigger programs and efficiently scan text files and process large data sets.

Master essential Java string processing with substring and indexOf methods, applying them to user input and text file data, while reinforcing string variables, character variables, and the charAt method.

Learn how the substring method in Java extracts a portion of a string by specifying start and end indices, with examples using five and seven in Eclipse.

Practice using the substring method in Java, handling user input and string length to avoid index out of bounds, and explore the indexOf technique to extract specific parts.

Explore indexOf and lastIndexOf to locate characters or words in a string from left-to-right and right-to-left, then use substring to extract data with zero-based indexing.

Practice using the indexOf, lastIndexOf, charAt, and substring methods in Java with Eclipse to locate characters, measure length, and extract a word from a sentence.

Learn to parse a single input string into first, middle, and last names using indexOf, lastIndexOf, and substring; print labeled lines and a final line with initials and last name.

design and implement a java project in eclipse that reads a full name, splits it into first, middle, and last using substring and indexOf, and prints the result compactly.

Master three important methods, including indexOf and lastIndexOf, to scan text files and locate specific data using Eclipse.

Learn to create objects from the scanner and print writer class, read text files and strings, and write two text files, while building foundational object-oriented programming in Java.

Discover how to use the scanner class in Java to create a scanner object, extract tokens with next, nextInt, nextDouble, and nextBoolean, and understand delimiters and closing the scanner.

Practice using the scanner object in Java with Eclipse, importing the utility package, and reading a string, an integer, a double, and a boolean, then printing and closing the scanner.

Learn to change delimiters in a Java scanner and handle basic errors, then build a word counter by looping with hasNext and counting tokens using a hashtag delimiter.

Learn to read a text file in Java using a file scanner in Eclipse, pairing it with a line-by-line scanner to iterate lines with nextLine, and properly close scanners.

Create a Java project in Eclipse, set up the file reader practice main class, and prepare a text file for reading with a scanner.

Learn to read a text file in Java with a file scanner in Eclipse, import needed packages, handle file not found errors, and parse lines to print names and ages.

Practice using a print writer with a file writer to write and append text, handle io exceptions, and persist user input via a dialog-driven loop.

Create a test results project, read student names, percentages, and pass flags from files with a file scanner and print writer, using try-catch for file not found and IO exceptions.

Create Java program in Eclipse that reads a section 3 project text file, parses first name, surname, and percent with a delimiter, and writes pass/fail results using a print writer.

Learn to use the scanner to read strings and text files, receive and process data into information, and store it for easy later retrieval.

Explore how arrays in Java hold a fixed number of values, learn to declare one-dimensional and two-dimensional arrays with square brackets, and apply zero-based indexing in Eclipse.

Practice using a one-dimensional integer array in Java with Eclipse, collecting five user inputs via a dialog, storing and printing them, and using the array length to determine capacity.

Practice two-dimensional arrays in Java with Eclipse by filling a 4x5 array using nested for loops and user input. Display the resulting matrix row by row to verify values.

Explore how the split method works with string arrays, acting like a scanner to split a string into tokens and size the array accordingly in the Java Masterclass course.

Learn to use Java's split method in Eclipse to split strings into arrays by whitespace or specific words, print results, and handle tricky cases to avoid errors.

Explore Eclipse work by parsing sport lists as strings, splitting them into arrays, and using an if statement with length to identify which student has more faults, then display winner.

Learn to build a Java project in Eclipse, collect user input via a dialog, split into arrays, and use length checks and a for loop to compare two players' sports.

Conclude this section by applying arrays to hold data, using scanners to read text files, and applying the split method, while introducing object oriented programming with methods and classes.

Learn object oriented programming in Eclipse by creating classes and objects and using reusable methods. Use a text file reader and a processor to produce output in your main program.

Explore how to use and create classes in Java with Eclipse. Learn about void methods and top methods, how to import utilities like the Scanner, and reuse fields in code.

Create a class and a void method in Eclipse, using an object to call the method that prints hello world and explains void versus returning values.

In Eclipse, build a Java project that demonstrates typed method creation to process a full name, extracting the first name and surname with substring and indexOf via Swing input dialog.

Learn how private variables restrict access to within a class, keeping core values protected from user tampering, and how to expose them via a public method that prints the value.

Create a separate scanner class with a file scan method, prompt for a file name using a Swing dialog, and read text files in Java with Eclipse.

Practice object-oriented programming in java by building a read and process class that reads a roster text file and formats each line into initials, surname, age, and gender initial.

Develop object processing with a file reader to scan two text files, identify the oldest person, format initials and age, and write results to the final text file.

See a complete Java project solution in Eclipse, where a reader scans text files, finds the oldest entry, processes results, and writes them to a final results file.

This conclusion wraps up the advanced Java programming course with Eclipse by reinforcing object oriented programming, building methods in your own classes, and valuing practice across projects.
