kotlin check if variable is initialized

To check if a variable is initialized in Kotlin, you can use the isInitialized property. Here are the steps to do that:

  1. Declare a variable: Start by declaring the variable using the var keyword. For example: var myVariable: Int.

  2. Check if the variable is initialized: To check if the variable is initialized, you can use the isInitialized property on the variable. This property returns true if the variable has been assigned a value, and false otherwise. For example: myVariable.isInitialized.

  3. Handle the initialized and uninitialized cases: Based on the value of the isInitialized property, you can handle the initialized and uninitialized cases accordingly. For example:

var myVariable: Int
if (myVariable.isInitialized) {
    // Variable is initialized, perform some action
    println("Variable is initialized")
} else {
    // Variable is not initialized, perform some action
    println("Variable is not initialized")
}

In the above code, if the variable myVariable is initialized, it will print "Variable is initialized". Otherwise, it will print "Variable is not initialized".

That's it! You have now checked if a variable is initialized in Kotlin using the isInitialized property.
