What is literal and different types of literals in java?
In Java, a literal is the source code representation of a fixed value and are represented without requiring computation. The various types are Integer, Floating-Point, Character and String literals.
In a Java program, all characters are grouped into symbols called tokens. Larger language features are built from the first five categories of tokens (the sixth kind of token is recognized, but is then discarded by the Java compiler from further processing). We must learn how to identify all six kind of tokens that can appear in Java programs. In EBNF we write one simple rule that captures this structure: token <= identifier | keyword…
There are several types of Java technology. Some examples of Java software are Java ME, Java EE, Java SE, and Java Card. Java made the JAVA development kit for those that develop in Java. There is also Java Virtual machine and some class libraries. Java is also famous for its languages like Clojure, Beanshell, Groovy, Gosu, Rhino, Kotlin, JRuby, Scala, and Jython.
You can look up a list of Java operators online, to get a complete listing. But the different types of operators include: mathematical operators (for calculations), logical operators such as "and" and "or", assignment, bit-shift operators, the "ternary operator" (for a shorthand "if"), and a few others.
Java is a programming language and a virtual machine that a java program can run in. The virtual machine allows the same Java application to run on many different types of computer, since the virtual machine remains identical. A Java applet is a special type of Java application that is coded specially to run as a plug-in to a web browser.
The whole idea of Java is to be able to run the same program on different types of computers (different "platforms" - combination of hardware and operating system). The Java Virtual Machine is what makes this possible. The Java program is compiled, not for a particular microprocessor, but for the Java Virtual Machine - a "virtual processor", so to speak. This JVM then interprets the compile program.
An operator is a symbol that does something in Java. for ex: "+" is an arithmetic operator that adds two numbers. ">" is a logical operator that checks if one number is greater than the other. There are many different types of operators in Java like Arithmetic, Logical, Relational and Assignment operators
