It is aslo known as repetitive structure. Loop structure is used to run the block of codes until the condition is satisfied. While in execution, the if the condition is true then it is executed if the condition is false then the loop is terminated and follows the next statement of loop. Loop structure continue to execute until the condition is satisfied and it is very useful in many areas because of this feature. In java programming language, there are three options to use repetitive structure. 1) ' while ' statement 2)' do-while' statement 3)' for ' statement 1)'while' statement In while statement, certain code of block runs which is inside the while loop structure until the condition becomes false. After being the condition false, the loop will terminate itself. Syntax:- while(<condition expression>) { //program code } 2)'do-while ' statement It is also a type of statement. In this type of structure, while exp...
Scanner class is used to take input from the user in java. It has many different methods to handle other task too. To use Scanner class you have to use import java.util.Scanner; then you have to create an object of Scanner class. After creating an object, you can use the scanner object to store variables from user. When user gives input it stores in it and later on we can assign the value in variable for further use. let't see one example of Scanner class. Here, how to calculate Simple Interest is displayed. Source code... package oop; import java.util.Scanner; public class ScannerDemo { // Scanner is a class, located inside java.util package // Scanner is used to take input from user in console public static void main(String[] args) { int t; double p, r; double si; Scanner in = new Scanner(System.in); System.out.println("Principle amount:"); p = in.nextDouble(); System.out.println("Enter rate:"); r = in.nextDouble(); System.o...
Long time ago I read that learning programming is so fun, if you didn't find learning programming fun then you must not interested or your teacher don't know how to teach the programming. There is also written that the programming teacher must be working on industry so that he/she could be able to teach you the way how to overcome the programming obstacles. At the beginning phase of studying programming language, I used to worry about what if i couldn't able to write the code clearly and understandable. I always used to worry about it. But one day my facilitator said that now you are developing your career in software industry. Don't ever worry about the clear code. Just you do mistake as many times as it takes to get the task done. Then after the task is done, be clear what you did, what you learned from mistakes and what problem is solved. Then always make a habit of writing comment in the source code. There are a lot of things that he told us, these are few. At...
