Classifications of Programing Language - ( in detailed knowledge )

 Hello learners , we have already seen three levels of programming language in our previous blog . in this blog we will extend it in detailed way . so lets start .



There are three level of programming language given below.

  1. Machine Languages or  ( Low Level Languages )
  2. Assembly Languages or ( Symbolic )
  3. Procedure Oriented Language or ( High Level Language )


Machine Language or Low Level Language :-
Machine language is a type of low level language consisting of binary digit ( 0 and 1 ) . Computers are the digital devices , they can only recognised binary data . Even every program , videos , images , characters of text , etc , all are present in the computer as in binary form . 
Computers are made up of electronic devices which can understands only high pulse ( 1) and low pulse (0) conditions . It is the lowest level of software . 
 There are two problems in machine language .
  • It is impossible to understand and remember a large of 0 and 1 's combinations . Like 010011010111100101010101010010111
  • Since every machine have their own machine language so it is almost impossible understand or communicate with other computers . 
Machine level languages are usually referred to as the first generation languages .

Assembly Languages or ( Symbolic ) :- 
Assembly language ( introduced in 1950 ) brought to reduce the complexity of a program written in machine language . It is also referred to a low level language and it is known as the second generation of  programming language .
Advantages of  an assembly language :-
  • In this language , we can locate and identify  syntax error , so it is easy to debug it .
  • The devolopment of an computer application using assembly language is easier in comparison with machine language .
  • It operates efficiently .
Point to be noted :
  1. Binary digit ( 0 and 1) of machine language are replaced with abbreviations of mnemonic code.
  2. During execution this code is converted into machine code with the help of compiler .
High Level Language :-
High level language are the programming language in which one can write their program which are independent to a particular type of computer  . These type of languages are much closer to human understandable language , this is why it is called high level languages .
It is more abstract , easier to use , more portable across the platform as compared to the low level languages .
 Before execution of high level languages , it is traslated to the machine language code with the help of compiler and interpreter .
The main requirement of this high level language is to overcome the limitations of low level language .
examples :- C , C++ ,  FORTRON etc.

  Problem Statement :  Video Link :   Click Here Create a class AutonomousCar with the below attributes: carld – int brand – String   noOfTestsConducted – int noOfTestsPassed- int environment – String grade – String Write getters, setters for the above attributes . Create constructor which takes parameter in the above sequence except grade. Create class Solution with main method. Implement two static methods – findTestPassedByEnv and updateCarGrade in Solution class. findTestPassedByEnv method: This method will take two input parameters -array of AutonomousCar objects and string parameter environment. The method will return the sum of the noOfTestsPassed attribute from autonomousCar objects for the environment passed as parameter. If no autonomousCar with the given environment is present in the array of AutonomousCar objects, then the method should return 0. updateCarGrade method: This method will take a String parameter brand, along with the array of AutonomousCar objects. The method
