  • The illegal start of an expression is a java error during the compile-time with the “javac” compiler. When the compiler detects that a statement does not follow the syntax rules of the java programming language, an illegal start of expression error message is displayed. These errors can occur due to so many reasons. In most cases, they are straightforward to solve as long as you can locate the line of code with the error. It can be as simple as caused by an omitting closing or opening bracket or a missing semicolon at the end of a line.

    The goal of every programmer is to save time in both programming and debugging. However, there comes a time when you write hundreds of lines of code. It’s very frustrating having to repeat the same code now and then. It is more frustrating when your code gets some error, and you will need to debug the whole program.

  • I was in the process of creating a simple calculator in java using Swing. My input fields include JTextFieald and JTextArea. These input fields are String, but I needed to deal with Integers in a calculator due to the mathematical calculations. This led me to thoughts of how I would be able to convert these Strings into integers?  That’s when I came across these two beneficial methods. The Integer.parseInt() and Interger.valueOf().

  • Arrays are one of the most important data structures in our daily life. An array is a group of similar typed variables that are referred to by a common.

  • Let’s take some time today and discuss this awesome feature in HTML “horizontal line.” First of all, you may need to know if HTML “horizontal line” is a tag or an attribute. You can find more about HTML attributes well explained here. In this case, the HTML horizontal line is a block-level element or, in other words, a tag.

    Linked List in C++

    by Moses N

    It’s always never too late to learn new skills. Let’s take some time and look at this fundamental and useful data structure in our daily lives. What is a linked list in C++? It’s a type of data structure that uses pointers for its implementation. It will be very wise for you to also look at pointers if you have not yet since they will give you a deeper understanding of the Linked List. Nevertheless, I will try as much as possible to make this simple and understandable.
