About Java Runtime Error

Java is an open source programming language with the help of which programmers can build websites, software applications as well as applications for the mobile platform. There are integrated development environments (IDEs) and virtual machine available too, for debugging Java programs. These tools allow programmers to test Java programs, especially during the compilation and execution stages.

Java Runtime Error

Getting a Java runtime error is a common issue, which is experienced by both beginners as well as professionals developers. But, you do not have to worry about this error, because there are solutions available that can help you fix issues like the Java runtime error quickly and effectively.

Why Does It Occur?

The “Java runtime error” usually occurs at the execution phase of Java code. When you create a program in Java, it must follow the required norms because Java is a case-sensitive programming language. Other than that, there may also be another situation, where the problem may not necessarily lie in the Java code, but in the Java Virtual Machine (JVM). It may possibly throw a runtime error message on the programmer’s computer screen.

Let’s take an example to show the Java runtime error when executing a piece of a simple Java program.

Here, let’s create a Java file called DemoA.java, where the following code will be placed for compilation and execution.

class demoA


public static void main(String[] args)


System.out.println(“Hello World!”);



Since, Java is a case-sensitive programming language, the sample code given above will compile successfully. However, at the time of execution, it will throw a runtime error. The reason is because it cannot find the DemoA.class file.

How Can You Resolve The Error?

If you are experiencing a Java runtime error on your computer and need a fix for it,  then you will find the solutions here.

Knowing that errors and issues can only occur in a Java program if a mistake has been made by the programmer, hence, the best solution or advise is to make the necessary checks, which are given as follows:

  • Missing quotes for strings

  • Referencing objects that do not exist

  • Mismatched single and double quotation marks

  • Using comparison operators incorrectly

  • Referencing an object that has no properties

  • Making other typo errors

Errors can occur if you are not being careful with not only the syntax of the Java programming language, but other inputs as well. Therefore, in order to get rid of the runtime error in Java, it is crucial that you ensure accuracy in your Java program.
