Runtime polymorphism occurs when an object is associated with functionality during runtime. Method overriding can be used to provide runtime polymorphism. The Java virtual machine selects the method to invoke during runtime, not at compile time. It’s also known as dynamic and late binding. M...

What happens to the program and how to deal with such run-time error? The first thing you need to know is that when an exception occurs, an exception object is created. In general, Java platform throws the exception object, signaling an unexpected situation such as divided by zero or acces...
Compile and Run Java Program: It's Two Step ProcessCompilation and execution of a Java program is two step process. During compilation phase Java compiler compiles the source code and generates bytecode. This intermediate bytecode is saved in form of a .class file. In second phase, Java ...
It is possible to change the metaclass at startup time by giving the metaclass a specially crafted (magic) class name and package name. In order to change the metaclass forjava.lang.Integerit’s enough to put a classgroovy.runtime.metaclass.java.lang.IntegerMetaClassin the classpath. This ...
The types of errors encountered when a software developer develops a Java application can be split into two broad categories: compile time errors and runtime errors. As the name implies, compile time errors occur when the code is built, but the program fails to compile. In contrast,Java run...
and lack of optimization based on platform or hardware architecture specifics. in contrast compilers are only executed once at the start of development, making subsequent execution times much faster since there is no need to continually interpret the source code each time it needs to run. what ...
It allows us to perform the same process in different manner. There are two types of polymorphism present in Java Compile-time polymorphism method Run time polymorphism method Today, we are going to discuss about the compile time polymorphism by using the Method overloading and Operator over...
In the examples, we saw the difference between compile-time and run-time constants. We also saw that the compiler uses compile-time constants to perform static code optimization. Finally, we looked at the usage of compile-time constants in switch statements and Java annotations. ...
But what is happening is if I open my application 4 days from now it displays the date current on that day and not today's date when I compiled my application. I know all objects are created at runtime in Java. But was interested does any one knows a trick on how to do this. Tha...
