How to Get a List of Current Open Processes Java?
It is essential for the user to know about the processes that are running in their system, be it foreground or background. To do so in windows we have a task manager but internally it uses a program called tasklist. Tasklist aside from giving us the currently running processes, it also gives us details like process id, session name, session and memory usage of each process. In this article we will see how we can get a list of currently open processes by using Java programming language. Algorithm Step 1 − Create a process that executes the tasklist.exe Step 2 ...
Read MoreJava Program To Reverse A Number And Find the Sum of its Digits Using Do-While Loop
What Is A Do-While Loop? Do-while loop is a Java environment used to iterate a portion of a code in a repeat manner. The process will run in a continuous way until the specified condition becomes satisfied as a true condition. It is always recommended for a do-while loop to execute at least one when there is no fixed number of iteration mentioned. In the Java environment, the do-while loop is known as an exit control loop. At the end of a loop structure, the do-while checks the whole condition to make the condition satisfied. For this the do while ...
Read MoreJava Program To Reverse A Linked List Without Manipulating Its Pointers
Linked List and Pointers In Java Linked list is liner data structure in Java environment, which use to store the elements in an adjacent manner. A linked list contains with some addresses and pointers which are used to create a link between the elements present in a list. There are two types of elements present in a linked list. Those are - data element and address element. The value of an element indicated by the data part where the address part helps to create a link between the elements aka node. In Java there is an another concept of ...
Read MoreJava Program to Return the Largest Element in a List
We can use an array loop to return back the largest element from a list. Primarily this method, known as the comparison model. The maximum number present here in a certain list will be compared with the all elements present in that particular list. The process considers “n” as a number of inputs which will store as data value in an array. After that the program will display the largest element on the output console after refining the loop. In this article today; we will help you to understand and write some Java code by which you can find the ...

Read MoreHow to Check Orientation of 3 Ordered Points in Java?
In this article we are going to find the orientation of 3 ordered points. Here orientation means that the given points form clockwise, anticlockwise or collinear shape in space. In the above diagram a, b, c are the three points which check the orientation of shape in space. We find the orientation of three given points by calculating the slope. To calculate slope and to calculate the orientation of 3 ordered points. Slope of line segmentSlope of line segment $(a, b):\theta=\left ( y_{b}-y_{a} \right )/\left ( x_{b} -x_{a}\right )$ Slope of line segment $(b, c):\phi=\left ( y_{c} -y_{b}\right )/(x_{c}-x_{b})$ And ...
Read MoreJava Program to Encode a Message Using Playfair Cipher
Encrypting is the task of transforming information into an unreadable format or cipher text. It is usually done to protect the confidentiality of information. There are many ways and algorithms to encrypt data. One such example is the Playfair cipher algorithm. In this article, we are going to see how to write a Java program to encode a message using Playfair cipher. Playfair cipher makes use of a 5X5 grid or matrix and a set of pre-defined rules. To encrypt, we require a key and the plain text to be encrypted. Steps Now let us see the steps to encrypt ...
