Our problem statement is to find the speed of internet. For this, our required inputs will be data in mega bytes (d) and time in minutes (t). We will make use of Scanner class in Java to read these inputs at runtime. Since, they are generally integers, which are primitive datatype...

If you just try to learn Java in a vacuum that means that you’re trying to learn syntax of Java and maybe you’re trying to write Command Line Programs to use the Java and it’s going to be hard because we don’t learn that way. The reason—the whole purpose of learning in gener...
At this point, we are assuming that you successfully installed the Java SDK and were able to run the sample programs that we showed you in Chapter 2. It's time to start programming. This chapter shows you how the basic programming concepts such as data types, branches, and loops are impl...
This pattern produces “hours”, “minutes”, “seconds”, “milliseconds”, and “timezone offset in hours (RFC pattern)”. This code displayed the time as “13:03:15.454+0530”. Usingparse() Parsing is the conversion of String into ajava.util.Dateinstance. We can parse a string to a...
The simple program in this lesson uses a Java API to print a line of text to the console. The console printing capability is provided in the API ready for you to use; you supply the text to be printed. Java programs are run (or interpreted) by another program called the Java VM. If...
Multithreading: Multithreading is a special feature of Java, enabling a programmer to make programs that are able to domultiple tasks at the same timeor at least giving an impression of being multiple tasks being executed at the same time, in a very smooth and interactive manner. ...
