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.

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.

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.

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.

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.

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 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.

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.

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.
