If we have a bunch of imports from the same package, then to avoid specifying each import individually we can import the entire package at once using the * operator:

    import com.packt.myproject.* 

Wildcard imports are especially useful when a large number of helper functions or constants are defined at the top level, and we wish to refer to those without using the classname:

    package com.packt.myproject.constants 
 
    val PI = 3.142 
    val E = 2.178 
 
    package com.packt.myproject 
    import com.packt.myproject.constants.* 
    fun add() = E + PI 

Notice how the add() function does not need to refer to E and PI using the FQN, but can simply use them as if they were in scope. The wildcard import removes the repetition...
