The key difference in java compared to other languages is the bytecode. Bytecode can be run by the java virtual machine on a specific operating system. Oak project which created java had a goal to create a virtual machine and a language that is simple to use. Write Once and Run Anywhere was the java marketing slogan. Java 2 version had Java Enterprise and Java Mobile editions. Java community process was created to develop java specifications from the industry and academia.<\/p>\n<p id=\"f41b\">JavaScript was invented and developed by Brendan Eich in 1995 at Netscape. This language was inspired by Java, Scheme, and&nbsp;Self. Sun and Microsoft started creating their own web-based products using javascript. Netscape created Mocha which evolved to javascript. Mocha was an application platform that can work with the LiveWire application server. Javascript was used on the client and server-side. Douglas Crockford came up with JSON which is a subset of Javascript syntax. Many languages like VBScript, Silverlight, Typescript have competed with javascript.<div style=\"display:inline-block; margin: 15px 0;\"> <div id=\"adngin-JavaCodeGeeks_incontent_video-0\" style=\"display:inline-block;\"><\/div> <\/div><\/p>\n<h3 class=\"wp-block-heading\" id=\"h-2-7-in-which-projects-do-we-need-java\"><a name=\"javaprojects\"><\/a>2.7 In which projects do we need java?&nbsp;<\/h3>\n<p>Java is used in projects which are based on object-oriented and modular design principles. Ecommerce, Mobile, and enterprise software projects need java. There are software games developed in java that are popular in the market.  Java is used for developing a microservices-based architectural system. It is used for service-oriented architectural systems.<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-2-8-in-which-projects-do-we-need-javascript\"><a name=\"jsprojects\"><\/a>2.8 In which projects do we need JavaScript?<\/h3>\n<p>Javascript is used in projects which are related to interactive websites and mobile applications.

Garbage collection is a feature that helps in collecting the resources which are free and released. Java developers cannot go beyond the allocated memory. In java, when the memory is consumed beyond the allocation, it throws an error. JavaScript requires lesser memory compared to java. This is used extensively for client-side scripting in web pages.<\/p>\n<h4 class=\"wp-block-heading\" id=\"h-2-10-2-exceptional-handling\">2.10.2 Exceptional Handling<\/h4>\n<p>In Java, exception handling is possible by using try, catch, and finally blocks.<em>Java Exception Handling<\/em><\/p>\n<p><span style=\"text-decoration: underline\"><em>Exceptional Handling -Java<\/em><\/span><\/p>\n<pre class=\"brush:java\">public class ExceptionExample{  \n  public static void main(String args[]) throws Exception{  \n  try{  \n   int result=36\/0;  \n   System.out.println(\" the result is \"+result);  \n  }  \n  catch(ArithmeticException exception)\n  {\n    System.out.println(exception);\n       \n    throw new Exception(\"division by zero\");  \n  }  \n  finally\n  {\n    System.out.println(\"finally block is executed at the end\");}  \n    System.out.println(\"code below is used for next steps\");  \n  }  \n}\n<\/pre>\n<p>JavaScript has try, catch, throw, and finally blocks to handle exception handling.<\/p>\n<p><span style=\"text-decoration: underline\"><em>Exceptional Handling-Javascript<\/em><\/span><\/p>\n<pre class=\"brush:java\">console.log(\"entering try-catch statement\");\n \ntry {\n  console.log(\"entering try block\");\n  throw \"thrown message\";\n  console.log(\"this message is never seen\");\n}\ncatch (e) {\n  console.log(\"entering catch block\");\n  console.log(e);\n  console.log(\"leaving catch block\");\n}\nfinally {\n  console.log(\"entering and leaving the finally block\");\n}\n \nconsole.log(\"leaving try-catch statement\");\n\n<\/pre>\n<h4 class=\"wp-block-heading\" id=\"h-2-10-3-multiple-inheritance\">2.10.3  Multiple Inheritance<\/h4>\n<p>Let us take an example to see how it is handled in Java and JavaScript.
