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:
Declare a variable: Start by declaring the variable using the
var
keyword. For example:var myVariable: Int
.Check if the variable is initialized: To check if the variable is initialized, you can use the
isInitialized
property on the variable. This property returnstrue
if the variable has been assigned a value, andfalse
otherwise. For example:myVariable.isInitialized
.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.
