Static also known as <\/span><\/span>Class level context<\/span><\/span><\/span><\/p>\n

Static —-Class Level<\/b><\/span><\/span><\/p>\n

No Matter how many object we create for that class, it will share the same static context. Whether it is block, properties and methods.<\/span><\/span><\/p>\n

We don\u2019t even to create an object to access a static context.<\/span><\/span><\/p>\n

We just need to use class name.<\/span><\/span><\/p>\n

Non Static —- Object Level<\/b><\/span><\/span><\/p>\n

For non-static context we need to create object to access the context.<\/span><\/span><\/p>\n

<\/p>\n

In the above example Withdrawl() method and CheckBalance() values will change to every bank customer but interest and Interest Calculation will be same for the entire bank customer.<\/span><\/span><\/p>\n

So here interest and calculateInterest() method is static and withdrawl() and checkBalance() methods are non static<\/span><\/span><\/p>\n

Now we will see about static blocks<\/span><\/span><\/p>\n

Static block is executed only once.<\/span><\/span><\/p>\n

It will be executed as soon as the class is loaded and before main method executed.<\/span><\/span><\/p>\n

<\/p>\n

Result<\/span><\/span><\/p>\n

<\/p>\n

If we have multi static block then once the class is loaded the static block will execute in order see the example bellow.<\/span><\/span><\/p>\n

<\/p>\n

Result.<\/span><\/span><\/p>\n

<\/p>\n

Now we will see about Static Methods.<\/b><\/u><\/span><\/span><\/p>\n

We are going to create static method inside a class like bellow example and we need to call it. <\/span><\/span><\/p>\n

t will work if we call by creating object also.<\/span><\/span><\/p>\n

<\/p>\n

Result.<\/span><\/span><\/p>\n
