If you will execute above code, it will go in infinite loop which you can terminate by pressing Ctrl + C keys. The following commands are used to compile and execute this program. The following program implements infinite loop. If you are using Scala, the while loop is the best way to implement infinite loop. Terminates the loop statement and transfers execution to the statement immediately following the loop.Ī loop becomes an infinite loop if a condition never becomes false. Click the following links to check the detail. As such Scala does not support break or continue statement like Java does but starting from Scala version 2.8, there is a way to break the loops. When execution leaves a scope, all automatic objects that were created in that scope are destroyed. Loop control statements change execution from its normal sequence. Scala program to create a user define function to return largest number among two numbers.
Scala program to demonstrate example of collection list and for loop. Scala program to print numbers from 1 to 100 using for loop with until to determine loop range.
#SCALA FOR LOOP CODE#
Like a while statement, except that it tests the condition at the end of the loop body.Įxecutes a sequence of statements multiple times and abbreviates the code that manages the loop variable. Scala program to print numbers from 1 to 100 using for loop. It tests the condition before executing the loop body. Repeats a statement or group of statements while a given condition is true. Click the following links in the table to check their detail. Scala programming language provides the following types of loops to handle looping requirements. A loop is a term that we use to describe code that executes a block of. Programming languages provide various control structures that allow for more complicated execution paths.Ī loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages − Flow Chart Instructor Lets take a look at the syntax required to create a loop in Scala. As an example, we’ll attempt to get the sum of a List of numbers both imperatively and functionally.
In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. Scala, like every programming language, provides us with the ability to write loops. There may be a situation, when you need to execute a block of code several number of times. Scala has 3 types of loop statements: while loop Repeats a statement or group of statements as long as a given condition is true. This chapter takes you through the loop control structures in Scala programming languages.
