How and why are variable names used in programming to process data?
Variable names are used so the code is readable. When the code is compiled to machine languages, it no longer uses the variable names to understand it's operations...sometimes variable names are kept as metadata to help debug but the computer does not need them to execute the program...they are for us so we can easily understand what we are doing.

"Java This keyword" is a reference to the current object, it is very helpful when you need to refer an instance of a particular Object from its available methods or using it's constructor, also "this" keyword helps us to avoid naming conflicts.The following are different ways to use java this keyword1) Using with instance variable2) Using with Constructor3) Pass / Return current instanceUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with ConstructorUsing this keyword inside constructor like followingthis("Sony", 20); it will call the constructor having same parameter

What is the difference between variable and identifier?
An identifier is simply the name of something, while a variable is an instance of something.For example:int x;Here, the identifier is "x," but the variable is the object whose name is "x." A: An identifier is a name of something. Typically used in computer programming, the term "identifier" is frequently used to name a variable (see below), a subroutine, are in reality, any place in memory in which data or code reside where a name would be useful. "MyBirthDate" might be a good identifier, pointing to a memory location where the data contianing your date of birth is stored. The term variable comes to us from mathematics, but is frequently used in computer science too. It refers to a value that varies. For instance: a + b = 5 In this case, the value of a and b can change, so long as the sum of a and b equal 5. The opposite of the term variable is constant. In the equation, E=Mc2, c is a constant that is equal to the speed of light in a vacu -- +- 186,000 miles per second. In computer science, the term "variable" is used synonymously with "identifier" when they are both used to point to memory that contains data that may be changed and will not always be the same. In Microsoft BASIC, the statement: Tomorrow = Today + 1 Today and Tomorrow are variables, and 1 is a constant.
