How to lock a File before writing in Java? Example
A file is one of the oldest ways to store data and share data but if you are
working in a shared file i.e a file that can be read or write by multiple
readers and writers, you need to make sure that the file is
locked before you try to write on it. This is needed to ensure that
someone doesn't overwrite the data you are writing. Fortunately, Java provides
a mechanism to lock a file before writing using the
FileLock
interface. You can get the handle of
FileLock
by using
FileChannel
for writing to a file. The
FileChannel
class is generally used to write faster in a large file and one of the common
ways to write binary data in Java.

Difference between Static and Dynamic binding in Java
Hello guys, if you are wondering what is difference between static and dynamic binding and how it affect your program execution in Java then you are at right place. When you call a method in Java, it is resolved either at compile time or at runtime, depending upon whether it's a virtual method or a static method. When a method call is resolved at compile time, it is known as static binding, while if method invocation is resolved at runtime, it is known as Dynamic binding or Late binding. Since Java is an object-oriented programming language and by virtue of that it supports Polymorphism. Because of polymorphism, a reference variable of type Parent can hold an object of type Child, which extends Parent.

How to calculate sum and difference of two complex numbers in Java? Example
From the last couple of articles, I am writing about coding exercises for beginners e.g. yesterday you learned how to write a program from matrix multiplication in Java (see here) and a couple of days back, you have learned the recursive binary search algorithm. To continue that tradition today I am going to show you how to write a program for calculating the sum and difference of two complex numbers in Java. If you remember the complex number from you Maths classes, it has two-part real and imaginary and to add a complex number we add their real and imaginary part separately, similar to subtract complex number we minus their real and imaginary part separately.
