  /* Do not use '==' operator for comparing strings in java.  Because '==' checks if both objects point to the same memory address or location  and .equals() compares values in the objects. This program is made using library functions and without using library functions. Here in this program I am using string library functions .equals() and .equalsIgnoreCase() which gives output as boolean values true or false. */ import java.util.*; public class str_cmp_cmd_line {      public static void main(String[] args)      {      System.out.println("First Input String ="+args[0]);       //Commmand line arguments always starts from 0 i.e. args[0]       System.out.println("Second Input String ="+args[1]);      System.out.println("By using string library function of equals()");      System.out.println("Input string1= "+args[0]+" & string2= "+args[1]+" are equal :"+args[0].equals(args[1]));      // Here equals() check

Following are the different types of Computer Programming Languages:   1) Procedural languages :  These are used to execute a sequence of statements that lead to a result. They use multiple variables, heavy loops, and other elements.  Examples: BASIC, C, Fortran, Pascal, etc.  2) Functional languages :  These languages avoid loops in favor of recursive functions. The primary focus is on the return values of functions and side effects are discouraged.  Examples: Lisp, Python, Erlang, Haskell, Clourje, etc.  3) Object-Oriented languages :  These languages view the world as a group of objects that have internal data and external accessing parts of that data and offer services that can be used to solve problems.   Examples: Simula, Java, C++, Ruby, Python, etc.  4) Logic-Based languages :  These languages let programmers make declarative statements and then allow the machine to reason about the consequences of those statements.  Examples: Prolog, XSB, Oz, ALF, Mercury, etc.  5) Script
