How To Set Path in Java?

Java is one of the most prominent programming languages that has conquered the IT world. To keep up with the growing industry, it is important to learn Java and the first step for obvious reasons is installing Java. After the installation, if you want to work with java without any hiccups one would need to set the java path. Following are the contents discussed in this blog:

Why Do You Set A Java Path?

The path is the most important environment variable of the Java environment which is used to locate the JDK packages that are used to convert the java source code into the machine-readable binary format.

Tools like javac and java can be used by setting the path. When you save your file in the java directory i.e where java is installed, it is not necessary to set a path. But if you are saving your file outside the directory, it is fairly necessary to set the path beforehand.

How To Set Java Path?
There are two methods to set the path.

1 Temporary path
2 Permanent path

Temporary path of JDK
It is very easy to set the temporary path of JDK. Follow the following steps to set the path.

1 Open the terminal or command prompt
2 Go to the path where the JDK/bin directory has been saved
3 Copy the path
4 Enter the following command in the command prompt

Permanent Path of JDK
To set the permanent path of the JDK on your system, follow the steps below.
Open System settings and go to advanced system settings.

Click on the environment variables in the tab.

Go to user variables and click on new.

Add the variable name as ‘path’.
Copy the path of the JDK bin directory.

Click ok.

Congratulations, you have successfully added a Java path.

Now that you have created a java path, you must master all the fundamental concepts in Java and start working on the skills to become a java developer. It takes a lot of practice and guidance to master advance java development because of its vast concepts. To kick-start your learning you can enroll to Edureka’s Java certification program which will help you in mastering all the skills and concepts to become a java developer.

What is for loop in java and how to implement it?
While programming, if a situation arises where you specifically know how many times you want to iterate a particular block of statements in your code, go for a “for” loop. In this article let’s learn about how to implement for loop in Java Programming Language.

What is for loop?

Programmers usually use loops to execute a set of statements. For loop is used when they need to iterate a part of the programs multiple times. It is particularly used in cases where the number of iterations is fixed!

For a better understanding, let me give you a pictorial representation!

Here, after initialization, the condition that you have assigned in the code is scanned, in case the condition is true, it would increment/decrement (according to your code) the value, and again iterate the code according to the condition that you have assigned. But, if your condition is false, it will exit the loop.

After this theoretical explanation, let me show you the syntax of the for loop!

The syntax is pretty simple. It goes as follows
Statement 1: condition before the code block is executed
Statement 2: specifies the condition for execution of the code
Statement 3: condition once the code has been executed

To make things clearer, let us implement the above-explained syntax in a Java code.
The code written below depicts how for loop is implemented in Java Language

I have taken a simple code to get you all acquainted with the concept of for loop. Inside the for loop, there are three statements that I have talked about in the previous segment. I hope you can now relate to them easily!

Firstly, Int i=0, is the initialization of an integer variable whose value has been assigned to 0.
Secondly, i<5 is the condition that I have applied in my code
Thirdly, i++, means that I want the value of my variable to be incremented.

After understanding the working of for loop, let me take you to another concept, that is Java nested for loop!
