Another example with what we have learnt

Hey I'm going to do an another example for more understanding about what i told you in previous post. One more thing i need to say that the static keyword. if we create a method with static keyword that method will be comman method. Just think like that. I'll teach you more about when i teach you OOP concept.
Let's  do little exmaple.

Open the netbeans and create a new project and inside the main method, do the followings,

Output shoud be look like this.

In the above example there is "+" sign. In the java "+" sign do two things.

• "+" with a string do the concatanation (join two strings) 

•  "+" with numbers do the arithmatic operation "addition"
