How many packages available in java?
A Java package is a mechanism for organizing Java classes into namespaces similar to the modules of Modula. Java packages can be stored in compressed files called JAR files, allowing classes to download faster as a group rather than one at a time. Programmers also typically use packages to organize classes belonging to the same category or providing similar functionality.· A package provides a unique namespace for the types it contains.· Classes in the same package can access each other's members.package is a container in which similar classes are grouped together.package avoid the redundance of classes. it also provide security to hide the code only by importing the packege which contains the required class.
What are the types of java program?

In main memory how many bits num variable will hold?
That depends on the programming language, and on the specific data type. Java, for example, has integers of different sizes; for example, an int uses 4 bytes, and a long uses 8 bytes. It also has shorter integer data types. Java also has different types of floating point numbers; for example, a double uses 8 bytes, and a float uses 4 bytes. Java also has classes for arbitrary-precision math (classes BigInt and BigMath); in this case, the size in memory for a number will vary, depending on the number of digits.That depends on the programming language, and on the specific data type.
