A Programmer's View Towards Java Errors

If you work with java, chances are that you have at one time or another experienced errors that require you to know how to fix java problems. These errors are common when working with java, but none the less can be very frustrating. Whether you are an experienced programmer in java or are new to the world of java, knowing how to fix java errors quickly becomes part of your job. There are some java errors that are most commonly made when working with java, and if you are familiar with them beforehand, it may help you prevent making them and learn how to fix java problems when they occur.

Top 8 Programming Errors Causing Java Errors

  1. Accessing the non static member variables from main or static methods- there are a lot of programmers who have problems accessing their member variables in the main method. The signature of the main is marked as static when means that we do not need to create an instance of the particular class to be able to invoke the main method. There are a lot of java errors that occur because there is not an instance of class of application that you are trying to access.
  2. Mistyping a name of the method when you are overriding the file – overwriting can allow programmers to be able to replace a method of implementation with a new code. When you want to fix java errors, overriding can be a very handy feature to have. But it is easy to mistype the method name and then you would not be able to override a method.
  3. Comparison assignment – this is a very common java error to make. If you are used to using other programming languages, you most likely have noticed that different operators are used and this can be very hard to figure out.
  4. Comparing two objects – using the = operator in java you are actually comparing two different object references as they point to the same object. You cannot compare two strings to see if they are equal by using the ==operator.  This can cause java errors.
  5. Comparison assignment – this is a very easy mistake to make. To fix java errors, you have to forget about the other programming languages that you have learned and worked with and know how to work with the comparison operators in java.
  6. Confusion over the passing by value and reference – it can be hard to fix java errors with this kind of error message because it can be hard to diagnose. You need to be able to understand both the kind of passing by values and passing by references in order to prevent java errors from occurring.
  7. Writing blank exception handlers – it can be hard to not write blank exception handlers and to ignore the java errors, but if you do have problems and need to fix java errors it can be hard to find the cause. Try using simple exception handlers instead.
  8. Forgetting that java is zero indexed – if you are used to other programming languages, you need to remember that in java, arrays are zero indexed and the first element index is zero.

Mistakes and errors are common when working with java, but if you learn to prevent the errors from occurring it can make it easier when you have to fix java errors.
