The standard approach to iterate over characters of a String is with index based for loop. Index 0 represents the first element, index 1 represents the second element and so on. Returns 0 if the object is equal to the specfied object. Kotlin array is represented by Array class, that has get and set functions, size property and other member functions. val str = "Hello Kotlin Strings" println(str.length) //prints 20 get(index): Returns the character specified at the particular index. The length of string s1 is: 5 Here, if we try to assign null to a non-nullable variable then it gives compiler time error.
