In our world today, there are different computer languages, and there are numerous of them still widely used, and it’s safe to say Java is one of them.
What is Java?
Java is a general-purpose programming language. It has features that readily supports programming based on different paradigms (Conceptualization of computing): Object-Oriented, Procedural and Functional. Characteristics of Java Java possesses different characteristics, and to mention a few, here are some of them:
•Simplicity
Java is simple because its coding style is immaculate and easy to understand. It removes complexity because it doesn’t use complex and challenging features of other languages like C and C++, which are as follows: Concept of Explicit Pointers, Storage classes, Preprocessors and header files, Multiple Inheritance, Operator Overloading, Goto Statements.
•Wide Variety of usage environments
•Robustness
Java is robust as it can handle runtime errors, supports automatic garbage collection and exception handling, and avoids explicit pointer concepts. Java has a powerful memory management system. It helps eliminate errors by checking the code during both compile and runtime. Java is a garbage-collected language – JVM automatically deallocates the memory blocks, and programmers do not have to worry about deleting the memory manually, as in the case of C/C++. Java also provides exception handling, which identifies runtime errors and eliminates them.
Errors in Java
In different languages, errors occur during compilation and other ways. Here we would see errors that happen in the Java programming language.
•Compile-time Errors (Syntax errors)
Compile-time errors occur when syntactical problems arise in a java program due to incorrect use of Java syntax. They are also known as Syntax errors.
•Runtime Errors
Runtime errors occur when a program is successfully compiled, creating the .class file but not running properly. It is detected at run time (i.e. during the program's execution).
•Logic Errors
Logical errors in Java are the most critical errors in a program, and they are challenging to detect. These errors occur when the programmer uses incorrect logic or wrong formulas in the coding.
