  • JVM- A program written in Java receives services from the Java Runtime Environment (JRE) software by issuing commands to, and receiving the expected results from, the Java software. By providing these services to the program, the Java software is acting as a "virtual machine", taking the place of the operating system or hardware for which the program would ordinarily be tailored. from the Wikipedia explanation of the Java Virtual Machine - read more of this
  • 8 Primitive data types in java

  byte	0
  short	0
  int	0
  long	0L
  float	0.0f
  double	0.0d
  boolean	false
  char	'\u000'

  • Casting is converting one data type to another. There is two kinds of casting one between primitives numeric types and Objects. Casting between primitives numeric types is used to convert larger values, such as double values, to smaller values such as doubles to integers. For Objects All classes are child classes of java.lang.Object, so you can freely cast any class to Object class, or any class within the same family.
