The document discusses key concepts in Chapter 3 of a Java programming textbook, including objects and reference variables, using predefined classes and methods, the String class, input/output, and formatting output. It explains how to declare and instantiate objects, call methods, use the String class, accept user input via dialog boxes, and format output with printf. The chapter objectives are to learn about objects, reference variables, predefined methods, the String class, input/output dialog boxes, formatting decimal output with String format, and file input/output.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

55. File Input/Output (continued) Java Programming: From Problem Analysis to Program Design, 5e The statement in Line 1 assumes that the file prog.dat is in the same directory (subdirectory) as your program. However, if this is in a different directory (subdirectory), then you must specify the path where the file is located, along with the name of the file. For example, suppose that the file prog.dat is on a flash memory in drive H . Then the statement in Line 1 should be modified as follows: Scanner inFile = new Scanner( new FileReader("h:prog.dat")); Note that there are two after h: . Recall that in Java is the escape character. Therefore, to produce a within a string you need . (Moreover, to be absolutely sure about specifying the source where the input file is stored, such as the flash memory in drive h: , check your system’s documentation.)
