Dependency Injection in Spring framework

Image
Before understanding Dependency Injection(DI) in Spring framework, I recommend you to understand Dependency Injection design pattern As explained in above link, Dependency Injection is a design pattern in which object's properties are set by external entity. External entity can be simple java class which configure object's properties. Spring core (IoC) container acts as external entity to configure object's properties. There are 2 ways in Spring framework to achieve DI. 1. Setter Injection 2. Constructor Injection Let's write simple example to understand DI in Spring framework. We will set primitive values in Employee class using setter injection. I have used maven to add Spring framework related jars. You can add these external jars in eclipse by right click on project --> Build Path --> Configure Build Path... --> Add external JARs --> select jar --> Ok.  Project Structure:  POM.xml:  <project xmlns:xsi="http://www.w3.org/...

divide by zero in Java

You might be thinking,  divide by zero will throw ArithmeticException. But this is not true for floating point numbers. Divide by zero throws ArithmeticException only when char or integral value are divided by 0. Below two operation throws exception 10/0 'A'/0 If floating point number is divided by 0, output will be Infinity . 10.2/0 -10.3/0 Output: Infinity -Infinity

Data types and Literals in Java

Image
Data types Data types category:   Data types summary: Literals A constant value which can be assigned to variable is called "Literal". Integral Literals All possible value of Integral data type(byte, short, int and long) are called Integral Literals. Default Value: By default every Integral literal is int type. When you assign a value in long data byte and that value is more than 2147483647(Maximum value for int) then compiler will give you error. Ex: long a = 3000000000; Error: The literal 3000000000 of type int is out of range  Even though we have used long data type and value is also within range of long but still compiler gives error because every integral literal is int type. We can resolve this error by specifying long type explicitly. We can specify long type by suffixing l or L . Ex: long a = 3000000000L; Number System: Integral Literal can be represented as Decimal, Octal and Hexadecimal number systems. L...
