Answer 1

TRUE is a reference to an object of the class Boolean, while true is just a value of the primitive boolean type. Classes like Boolean are often called "wrapper classes", and are used when you need an object instead of a primitive type (for example, if you're storing it in a data structure).

semi colon stops for long time but comma for short time

There are several ways to declare variables: ... dataType variableName; This declares a variable, declares its data type, and reserves memory for it.

java file contains your Java source code while a . class file contains the Java bytecode produced by the Java compiler. It is your . class files that run on the JVM to execute a Java application.
