About Java:- Java is  a complete technology or platform,  which is used to create small scale to large scale application’s using Java Programming language, Java Development Kit and Java Frameworks. Java Technology Provide a complete platform to compile and execute the java program code using JDK and JRE . Java code converted into byte code by java compiler under JDK. Java Technology uses JVM (Java virtual machine ) to execute java byte code to any operating system hence Java is platform-independent but JVM dependent. JVM  is part of JRE. JVM is a subpart of JRE which is also called the virtual operating system of Java. In the developer machine, JDK and JRE both are required, but in the client machine, only JRE is required. About Java Programming language:- Java programming language is an Object-oriented programming language which is used to create a real-world based application for end-users. ...

Java Fundamental Interview Question:- Test your Java Fundamental Skills  Java Fundamental Question is the first impression of the interview, if you not answering this then it provides a bad impression to the interviewer during the interview because you know first impression is the last impression. hence if you know very well advance skill and not know fundamental skills then you will never select in the interview. now I am helping you to provide fundamental interview questions of java. Q1)  What is Java?  Java is programming language or technology? initial stage Java was programming language? Q2)  Explain System.out.println(), what is System, what is out, what is println()? Q3)  How to take input from user's, explain System.in, what is Scanner class?, It is possible to take input without using Scanner class? Q4) Explain public static void main(), what is public, what is static, what is void, what is main()?, what is String args[] in main(), can we change args id...

Software Tool For Java:- ........................................................................ 1 JDK + JRE  JDK (Java Development Kit) it is used to compile java program code to byte code. .JAVA ----> .Class JRE  (JAVA Runtime Environment) it is used to execute byte code(class file) to machine code using JVM(Java Virtual Machine). JVM is the virtual executor for java program code but JVM is operating System dependent. but .class file is common for all JVM. note:-  for developer or learner machine  :-  JDK+JRE for client machine :-   JRE (Java runtime environment) ................................................................................................................................................ How we check Java is installed in machine? go on program files and check Java (JDK+JRE) How we check that Java path is set or not? command prompt and type javac. if javac describes then the path is set. int...

---Question for all Java learners and Java Job seeker--- In this article, I will discuss, some important questions of java. What is System.out.println() in Java?  What is public static void main(String args[])? If you know advance questions then ok, if you do not know silly questions then you will definitely be rejected on the interview hence focus on fundamentals then go for an advance topic. What is System.out.println() in Java?   System is the predefined final class of Java, which exists under java.lang package, It is used to manage input and output operation in java. When we want to take input from the keyboard in Java then System.in the reference variable will use, if we want to display output on any output screen such as to monitor, laptop, desktop, etc then System.out the reference variable will work. out is the static reference or static variable of PrintStream Class which is declared under System class. println():-   It is the predefined method of Pri...

1)  Check Java Environment Java software is installed in the machine or not, In the windows machine, we can check under c:/program files/java folder it should contain JDK and JRE both. JDK means Java Development Kit, It provides program compilation means convert java program code to byte code. JRE means Java Runtime Environment, It is used to Execute Java Byte Code to machine code using JVM (Java Virtual Machine), JIT (Just-in-time) Interpreter exist under JVM which is used to execute byte code result. If the Java environment is not set then install JAVA using JDK and JRE. 2)    Check the Java Environment path that it is set or not.  Open the command prompt and type javac , if javac will be described then the path is set otherwise the path is not set if javac not recognized internal or external command ... How we set java path:- Right click on mycomputer----> propeties  ---> Advance System setting ----> Environment Variable-----> New --->  ...

  Autocomplete TextView and Multiple AutocompleteTextView:- Autocomplete is used to provide autosuggestion text according to input char, if we want to get suggestions  for multiple word using comma or another separator that is called tokenizer then we can implement multi Autocomplete Textview for multiple searching of data. AutoCompleteTextView Example:- package com.example.customdrawer; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.AutoCompleteTextView; public class MainActivity3 extends AppCompatActivity { AutoCompleteTextView act ; String course [] = { "JAVA" , ".NET" , "PHP" , "iOS" , "Android" , "Android Advance" , " JAVA Advance" , "J2SE" , "J2EE" }; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout. a...

---How we create the first program in Java --- 1)  First, we check that Java is installed in machine or not      go into c:/program files/Java/JDK/bin                   c:/program files/Java/JRE/ 2)  If this folder does not present then download Java software and install it 3)  Check Java environment path, open command prompt then type javac if javac is not recognized as an internal or external command, operable program then java path is not set 4)  if path is not set then set path using following step    4.1)   Right click on this PC ---> Properties ----> Advance System Setting ----> Environment Variable ---> new --->  Variable Name:-    path Variable Value:-    C:\Program Files\Java\jdk1.8.0_121\bin Click Ok ---> Ok --> Ok restart command prompt open command prompt type javac if javac description will be shown then P...

Angular Framework Introduction .......................................................................................................................................................................   before study this first you learn JS and Jquery:- https://www.shivatutorials.com/search/label/JAVASCRIPT https://www.shivatutorials.com/search/label/Jquery It is a javascript framework which provides an MVC design pattern to develop dynamic web application using HTML and JavaScript Object.
