#While loop java free
But hey, maybe that's just me! We're all free to pick our own flavor. When I read while(true), I just cannot be that sure anymore. When I read for( ), I feel secure knowing the developer will brake the execution path somewhere. Therefore, and I know it sounds crazy, but although while(true) reads better in English, I think for( ) better express your intent and is more akin to the Java programming language.
Also, it saves you a couple of keystrokes! =) ( not that it matter) Introduction to Loops in java in Hindi JAVA For loop vs While Loop vs Do While Loop Java For Loop in Hindi Java Simple For Loop in Hindi Java Nested. Adding the true in there feels a bit like hacking.įor( ) on the other hand is a "real loop", albeit an empty one.
while(true) is a bit like if(true), both of which I think has been made legal only for the added comfort of the masses. The while-loop "should" require a boolean expression, not a boolean constant. Me personally, I favor for( ) and my reasoning goes a bit like this:
#While loop java code
I read a lot of source code from the Oracle distributed JDK, and I cannot easily remember that I've seen a while(true) statement in their code, but I have seen a whole lot of for( ) statements in their code.
In the body of do loop, we have written two statements: One statement is printing the current value of i and the another statement i.e. The value 1 is taken because we have to print from the number 1. It repeats a statement or block while its controlling expression. The while loop is Java’s most fundamental loop statement.
#While loop java how to
In the above program, we have declared and initialized the variable i1. In this quick article, we will learn how to use while loop with examples. For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking 'while the number is not between 1 and 10'. Java Program to print 1 to 50 using do while loop. This tutorial discussed how to use both the while and do.while loop in Java. A 'While' Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. Java Tutorial fr Beginners - While loop executes a set of statements repeatedly until a given condition remains true. The do.while loop executes a block of code first, then evaluates a statement to see if the loop should keep going.
