 Variable in Java is a data container that stores the data values during Java program execution. Every variable is assigned a data type, which designates the type and quantity of values it can hold. Variable is a memory location name of the data. The Java variables have mainly three types: Local, Instance and Static.

 Data Types are divided into two group -
-* Primitive - byte,short,int,long,float,double,boolean and char
-* Non-Primitive - String, Arrays and Classes

 Java has the following conditional statements:

-* Use `if` to specify a block of code to be executed, if a specified condition is true
-* Use `else` to specify a block of code to be executed if the same condition is false
-* Use `else if` to specify a new condition to test; if the first condition is false
-* Use `switch` to specify many alternative blocks of code to be executed
-* Use `?,:` operator to specify one line condition

 A method/function is a way to perform some task. Similarly, in programming like Java, a function method is a block of code written to perform a specific task repeatedly. It provides reusability of code. We write the function once and use it many times. It works on the 'DRY' principle i.e., "Do not repeat yourself".

 Steps -
+
 1. Define function - datatype function_name(parameters){body}
 2. Call function - function_name(values)

 As the name indicates itself, a **Data Structure** is a way of organizing the data in the **memory** so that it can be used efficiently. Some common data structures are array, linked list, stack, hashtable, queue, tree, heap, and graph.

-* Array allocates continuous memory for homogeneous data
-* Linked List stores data in nodes with references
-* Stack follows Last In First Out principle
-* Queue follows First In First Out principle

 Java is a programming language and computing platform first released by Sun Microsystems in 1995. Java is a general-purpose, class-based, object-oriented programming language designed for having lesser implementation dependencies. It is a computing platform for application development. Java is fast, secure, and reliable, therefore. It is widely used for developing Java applications in laptops, data centers, game consoles, scientific supercomputers, cell phones, etc.
