How to set java path in Windows-10

Java / javac is not an internal or external command error will face when we didn't set java installation path properly. Here are the different ways to set the java path.

Set java path: When java installation completes, it will creates two sub directories under the top directory of Java. These two sub directories are jdk_version and jre_version.

For ex: you have installed JDK, in program files directory in your local directory the directory will generate with the name of JDK_<Version>. In JDK directory that can create the list of folders. Like bin, jre, etc. There are 2 types are there to set the java path:

  1. By using the Command Prompt (Temporary)
  2. By placing in the MyComputer (permanent)
1.Temporary Path:         First select the bin path under the jdk/jre directory. Follow these instructions.
Start Menu ---> click on Run ---> type cmd, click on enter ---> C:/set path=c:\j2sdk1.6.07_01\bin;

 2.Permanent Path:         First select the bin folder under the jdk/jre directory. Follow these instructions.
Right click on MyComputer ---> go to Properties ---> Advanced --->Environment Variables ---> in System Variables ---> path ---> edit/new ---> Path: c:\jdk1.6.07_01\bin.

 In User Variables ---> Classpath ---> edit/new ---> Class path: c:\jre1.6.07_01\lib;

 Note: In above, System/User variables path/Classpath is already available in that time you can choose only "Edit" button. If that are not there in that list you can select the "New" button and set name as well as path.

 How to check your setting java path working perfectly or not?          Open the Command Prompt (CMD), write java (or) javac click ENTER button. That will display the list of commands on the command prompt. You will get the below exception when you didn’t set the java path properly.
For Ex: javac / java is not an internal or external command
Note: You’re setting the path through the Command prompt, which is not permanent. That can be useful for before shooting down your Computer. Once you restated/shooting down your computer that java never works, that needs to set path once again.

 You’re setting the path in MyComputer that is permanently placed. Once you will set java path in environment variables that will be the permanent.

 How to set the Java path in Windows 8 / 10?        
Open START (or) press windows button ---> Choose Control Panel ---> choose System option ---> choose advanced tab ---> Environment Variables

 ---> In System Variables ---> path ---> edit/new ---> Path: c:\jdk1.6.07_01\bin;

 ---> In User Variables ---> Classpath ---> edit/new ---> Class Path: c:\jre1.6.07_01\lib;

Multithreading in java with example

Multithreading  is one of the most important concept in core java. In this article we will learn what is multithreading? , what is the use of it? and What is the use of Synchronization and when to use it?  with detailed examples. At a time, two or more threads are accessing the same object is called as Multithreading  in Java .  First, we will create two threads for two objects. It is also possible to run two or more threads on a single class object. In this case, there is a possibility to get unreliable results. If the two threads are perform same task, then they need same object to be executed each time. For your better understanding, take an example of any reservations like, railway, movie ticket booking,etc. Let us think only one berth is available in a train and two passengers are asking for that berth. The first person has sent a request to allocate that ticket/berth to him. At the same time, the second person also sent a request to allocate that ...

Prime, Fibonacci and Factorial number with example in java

Prime number, Fibonacci series and Factorial number programs are most commonly asked questions in interview. Read this article to know what is and how to write programs for prime number, fibonacci series and factorial number. Prime Number: prime number is natural number greater than 1 that has no positive divisor other than 1 and itself. A natural number greater than 1 is not a prime number, is called Composite number . For example, 7 is a prime number. Because it can divide with 1 and 7 only. Where as 8 is composite number. Since it has the divisor 2 and 4 in addition to the 1 and 8. The below example represents the finding the passing number is prime number or not. If the passing number is prime number it will print true otherwise it will print false. package com . javatbrains . practice ; public class PrimeNumber { public boolean isPrimeNumber ( int number ) { if ( number <= 1 ) return false ; // There's only one ...

How to sort list of objects in java with examples

We could achieve list of objects sorting in java by using sort() method which is available under Collections class as well as by using Comparable and Comparator  interfaces. Comparable and Comparator are two interfaces in java used to sort list of objects. These interfaces are available under java.util package along with Collections  class and other classes and interfaces. Comparable interface contains the method of       public int compareTo(Object obj) Comparator interface contains the method of       public int compare(Object obj1, Object obj2) The compare() and compareTo() methods will return negative integer(-1), or zero(0) or positive integer(1). When the first obj1 is less than obj2 method will return negative integer. When obj1 is equals to obj2 will return zero and when obj1 is grater than obj2 it will return positive integer. If it's objects are stored in any Collection classes like ArrayList, H...

A: String is a class in java.lang package. But, in java, all classes are also are considered as data types. So we can take String as data type also. Q2:  What is the difference between == and equals() methods in java? A: == operator compares the references of the String object. It does not compare the content of the object. equals() method compares the contents. While comparing the Strings, equals method should be used as it yields the correct result.

Store file into table by using JDBC with example

To store large data files or text files into database table, we will use CLOB (Charecter Large Object) datatype of SQL . By using CLOB it is possible to save entire text book or a file or resume into a column of data table. If your using MySQL database instead of CLOB use LONGTEXT to save file into datatable. For saving files into a data table, we need to create one table which will contains a column type as CLOB to store files. Here, is the query to create a data table. 1 2 3 4 create table myfiles( file_id int ( 10 ), file_name varchar ( 30 ), file_type LONGTEXT); Once table creation completes, these table contains the 3 columns one is file_id represents the file id, file_name represents the name of the file and finally file_type will get save entire file into the table column. Now, we will move to write a JDBC program which will saves the file into the newly creating table. Here is the JDBC program, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16...
