Before we jump on for each that is our topic let’s first discuss the for each loop in java. For each loop in Java would like to be: class For_Each { public static void main(String[] arg) { { int[] marks = { 12, 32, 97, 126, 130 }; int highest_marks = maximum(marks); System.out.println(“The highest score …
We have often encountered scenarios where we want to use a function to return a value, like say a function to return a Boolean if passed String contains special characters, this is what exactly we will try to understand in this tutorial. Kotlin is a simple way of doing it by using return statement.
Jump statements are evident to us from the last topic in which we discovered the use of break condition which can be used with or without labels. This topic can be taken as an extension of the same. Break is a statement which is used to end or terminate the flow of control once it …
We have seen the usage of Flow of Control which allows us to quickly move apply conditions, now in this tutorial we will encounter the scenarios to be catered when the flow needs to be broken or redirected. The way kotlin has given us some altered and improved for loop and a modern day switch …
Before we discuss loops, let’s go back in time and remember those days when we used to be punished and teachers told us to write: “I will not repeat the same mistake” a 100 times. Understanding that pain and easing that effort programming languages came up with repeated conditional statements which ease the programming effort …
Before we jump on see what Kotlin has to offer in terms of for loop, let’s first recap the one we have used in Java. A typical Java for loop would like below: for (int i = 0;i<10;i++){ System.out.println(“Number is ” + i); }
If you are familiar with Java, then no course in Java is possible without flow of controls in which the switch forms a very important lesson. A typical switch looks like below: switch(weekNumber){ case 1:System.out.println(” MONDAY “); break; case 2:System.out.println(” TUESDAY “); break; case 3:System.out.println(” WEDNESDAY “); break; case 4:System.out.println(” THRUSDAY “); break; case 5:System.out.println(” …
In this tutorial you will learn about kotlin if, else and nested if else expression. The if expression is definitely one of those constructs which lets us simplify our task of determining conditions during a program flow. Or rather, for performing any decisions in the program we look up to the if statement first, before …
