The only thing that can actually be "caught" at runtime is an exception. An exception is not a run-time error as such; it only becomes a runtime error if it is not caught in which case it becomes an unhandled exception. An exception is handled the moment it is caught, and therefore isn't an error. Depending on the nature of the exception, there may be no need to alert the user that an exception has even occurred.
Runtime errors include logic errors and system errors. Logic errors are bugs that can be identified at runtime. System errors are a bit more problematic because system errors do not throw exceptions so we cannot catch them. However, many can be resolved at runtime before they become system errors. Divide by zero is an example; always check your divisors are non-zero before executing any division operation. Hardware malfunction's, on the other hand, are often beyond our control, but they are not really run time errors unless they occurred because of our code rather than in spite of our code.
The if statement.
The only program that executes during compilation is the compiler. The compiler produces one object file for each translation unit compiled. When all translation units are compiled, the object files can then be linked together by executing the linker.
Languages are either "Compiled languages" or "interpreted languages": - A compiled language will use a compiler which is another program that checks your code and then converts it to the correct machine code for the machine it is intended to run on. You can only run the program after you have compiled it. A compiler can help spot syntax errors and certain semantic errors and will give you a "compilation error". - An Interpreted language can be ran directly as long as you have another program called the interpreter which translates your code into machine code whilst it is running. This means certain errors will not be caught before runtime (There is no concept of a compilation error) and so you won't know until runtime if certain errors are present in your code
Fatal errors are errors or exceptions that cause a program to abort. You solve fatal errors by examining the source code to determine what is causing the error. If the error is an exception, it can be caught. That is precisely why we always place a catch-all exception handler in the main function. Once we know where the exception was raised we can write code to specifically deal with that exception -- at or near the point it was actually raised. However, not all fatal errors throw exceptions. For example, a divide by zero operation is a fatal error because your program has allowed the system to attempt an illegal operation for which there is no reasonable means of recovery. The only solution is to avoid invoking illegal operations; test your assumptions and always assert that all operands are within the acceptable range of the operator. Fatal errors can also be caused by hardware failure, such as bad RAM, which is beyond the remit of applications programmers.
This seems to be both platform- and implementation-dependent. In some cases, properties may only be stored in memory, and will lose their value once the JVM exits. In other cases, properties may be written to disk and restored each time your program executes.

A CPU does math and accesses memory.

Exception handling is largely the same for both. The only real difference is that C++ has no 'finally' clause which always executes whether an exception occurs or not. Another difference is that Java throws exceptions and errors, but errors cannot be handled since programs cannot handle errors -- such as the JVM out of memory error.

That refers to anything that happens while you run the program. For example, the compiler may detect certain problems while you compile the program, but certain errors are bound to happen only when you actually run the program - i.e., at runtime.

Johnny not only caught the baseball his friend tossed to him, he also caught the flu.
Syntax error can be found during compilation. Runtime error can be found only when you are trying to execute your program. Syntax errors are those which are caused by incorrect usage of the programming language. All programming language compilers are designed to detect and report such errors done by the programmer Runtime errors are those which are caused by incorrect usage of programming logic. for example a runtime divide method will throw a run time error if the divisor is '0' because numerically you cannot divide a number by 0
Error estimation involves figuring out the number of errors in a program. This calculation is used not only for computers but also for some equations in math like linear equations.
