CODE EXAMPLE FOR JAVA

what is var in java

The var keyword was introduced in Java 10. 
Type inference is used in var keyword in which it detects automatically 
the datatype of a variable based on the surrounding context. 
The below examples explain where var is used and also where you can’t use it.
  

// Java program to explain that
// var can used to declare any datatype
  
class Demo1 {
  
    public static void main(String[] args)
    {
  
        // int
        var x = 100;
  
        // double
        var y = 1.90;
  
        // char
        var z = 'a';
  
        // string
        var p = "tanu";
  
        // boolean
        var q = false;
  
        // type inference is used in var keyword in which it
        // automatically detects the datatype of a variable
        System.out.println(x);
        System.out.println(y);
        System.out.println(z);
        System.out.println(p);
        System.out.println(q);
    }
}
