1. Java Code Blocks ({ })

Curly braces are used to bracket code blocks including classes and the methods within a class.

For Java, JavaScript, PHP, and C++, I prefer to put the first { at the end of the first line of the code block as in the example above because I see moreJava codeformatted that way.

6. Java Overview and History

Promoted as a single source cross-platform runtime system (Write Once, Run Anywhere). Java builds on and in some ways simplifies the object oriented features of C++. Java applications are typically compiled to byte-code and can run on any platform running the Java Virtual Machine (JVM).

Target Platforms: Java is suitable for creating many types of cross-platform applications that target the JVM including desktop business applications.

8. Java String Concatenation (+ or append)

Java String Concatenation

In Java, you use either the String concatenation + operator or StringBulder class methods such as append. Since Java compilers frequently create intermediate objects when the + operator is used and don't when StringBuilder.append is used, the append method is faster than the + operator.

In general, use the convenience of a + operator when speed is not an issue. For example, when concatenating a small number of items and when code isn't executed very frequently. A decent rule of thumb is to use the + operator for general purpose programming and then optimize the + operator with StringBuilder.append as needed.

  • ++ Increment operator by 1
  • -- Decrement operator by 1
  • ! Logical complement operator (inverts the value of a boolean)
  • ~ Bitwise inversion operator (works on integral data types)
