Keywords or Reserved words are the words in a language that are used for some internal process or represent some predefined actions. These words are therefore not allowed to use as variable names or objects. Doing this will result in a compile-time error.
Example:
object Main
{
def main(args: Array[String])
{
var p = 10
var q = 30
var sum = p + q
println("The sum of p and q is :"+sum);
}
}
|
Output:
The sum of p and q is :40
Scala contains following keywords:
| abstract |

| class |
| def |
| do |
| else |
| extends |
| false |
| final |
| finally |
| for |
| forSome |
| if |
| implicit |
| import |
| lazy |
| match |
| new |
| null |
| object |
| override |
| package |
| private |
| protected |
| return |
| sealed |
| super |
| this |
| throw |
| trait |
| true |
| try |
| type |
| val |
| var |
| while |
| with |
| yield |
| >: |
Example:
class GFG
{
var name = "Priyanka"
var age = 20
var branch = "Computer Science"
def show()
{
println("Hello! my name is " + name + "and my age is"+age);
println("My branch name is " + branch);
}
}
object Main
{
def main(args: Array[String])
{
var ob = new GFG();
ob.show();
}
}
|
Output:
Hello! my name is Priyankaand my age is20
