We can use the **`hashCode()`** method is used to calculate the #key# hash value:  a uniquely identified numerical value. #key# of the stated string or a given integer. 

# Method definition
```
def hashCode(): Int
```

# Syntax
- Integer value:
```
int.hashCode()
```
- String value:
```
String.hashCode()
```

Calling this method returns an integer value which is the *hashCode* of the specified string/integer.

> `hashCode` of an integer may be equal to the integer itself. 

# Code
Let's have a look at a coding example to understand it further:



object Main extends App {

// string hashcode  
  val result = "Hello".hashCode()
  println(result)

// integer hashcode  
  val result1 = 123.hashCode()
  println(result1)
}
