Java, a sophisticated programming language, has been dominating a number of ecosystems for quite a while. Portability, automated garbage collection, and its gentle learning curve are some of the things that make it a great choice in software development. However, like any other programming language...
Here comes one valuable tool that aids in identifying such errors: Error Prone. Error Prone is a library maintained and used internally by Google. It assists Java developers in detecting and fixing common programming mistakes during the compilation phase. In this tutorial, we explore the ...
As with any language there are common errors (or bugs) which programmers make. In some cases these are picked up by the compiler, but there are still many which slip through the net. It is always useful for someone learning Java (or indeed for those who have more experience but wish to...
Common C# Programming Mistake #9: Shying away from exceptions C# continues its enforcement of type safety into runtime. This allows you to pinpoint many types of errors in C# much more quickly than in languages such as C++, where faulty type conversions can result in arbitrary values being as...
Integration with Modern Java (e.g., Java 8+ Features like Lambdas with Strategy) Modern Java features, such as lambda expressions, method references, and functional programming, can be leveraged to simplify the implementation of design patterns. For example, the Strategy pattern can be implemented...
NPE is perhaps the most common problem in programming languages, which Null's inventor, Tony Hoare, called a billion-dollar mistake. There is no built-in syntax for handling Null values in Java, but there are still some relatively elegant ways to help us avoid NPE. ...
Error Prone is a static analysis tool for Java that catches common programming mistakes at compile-time. publicclassShortSet{publicstaticvoidmain(String[]args) {Set<Short>s=newHashSet<>();for(shorti=0;i<100;i++) {s.add(i);s.remove(i-1); }System.out.println(s.size()); } } ...
Programming languages carry some differences in rules and punctuation, so some syntax errors may appear more frequently than others. However, whether you’re coding in Java or Python, syntax errors need to be corrected for the program to run correctly. Here are some of the most frequent syntax...
Semantic Errors In addition to verifying that your program is syntactically correct, the compiler checks for other basic correctness. For example, the compiler warns you each time you use a variable that has not been initialized: Testing.java:8: error: variable count might not have been initializ...
This section covers some common problems that you might encounter when writing Java applets. After each problem is a list of possible reasons and solutions. Problem: My applet does not display. Check the Java Console log for errors. Check the syntax of the applet's Java Network Launch ...
