Which window shows the output of the Bluei program?
Answers
Answer:
Execute the class (executes the function associated with that object.)
Explanation:
A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Bill Atkinson of Apple Computer (now Apple Inc.) for their Lisa project.[1] Often, single-clicking selects (or highlights) an object, while a double-click executes the function associated with that object. Following a link in a modern web browser is accomplished with only a single click, requiring the use of a second mouse button, "click and hold" delay, or modifier key to gain access to actions other than following the link. On touchscreens, the double-click is called "double-tap"; it's not used as much as double-click, but typically it functions as a zoom feature. ("triple-tap" sometimes used to zoom the whole screen.)
Answer:
Option [b] is the correct option.
Explanation:
You can create Java programmes quickly and easily with the help of the development environment BlueJ. The following are its primary attributes:
- In contrast to business-oriented settings like NetBeans or Eclipse, BlueJ's interface is purposefully smaller and simpler. Because of this, newcomers can get going more quickly and without feeling overwhelmed.
- BlueJ was specifically created with pedagogy in mind to be used in the classroom. A website with a tonne of teaching resources is available, as is a popular textbook made for introductory university/college courses with BlueJ. BlueJ that is interactive enables object interaction. You may examine their value, use them in method calls, provide them as arguments, and more. Without compiling, Java expressions can also be called directly. BlueJ is a capable Java graphical shell and REPL.
- Runs on Linux, Mac OS X, Windows, and other Java-supporting operating systems is Portable BlueJ. A USB stick may be used to run it without needing to be installed.
- Despite being nearly fifteen years old, Mature BlueJ is still supported and updated by a full-time crew. We strive to reply to all requests for technical help within one working day.
- Innovative BlueJ contains a number of features that have never been seen in other IDEs. Among its early BlueJ features were the object bench, code pad, and scope colouring.
