Mortgage Calculator with User Input and Mathematical Expression - Example0005 In this code sample, we will see how mortgage(EMI) calculator can be made Mortgage formula M=P * (r(1+r)**n)/((1+r)**n-1) will be used. Scanner Class will be used to get user input. We need to get the rightly formatted output (with dollar sign as currency). For this purpose we will use Class NumberFormat:NumberFormat.getCurrencyInstance. We use NumberFormat.getCurrencyInstance method. Keyword: java, mortgage calculator, user input, scanner, currency format, dollar sign, numberformat, getcurrencyinstance package com.swprogramdeveloper; import java.text.NumberFormat; import java.util.Scanner; public class Main {     public static void main(String[] args) { // write your code here         //Mortgage Calculator         Scanner userInput = new Scanner(System.in);         System.out.print("Please Input the Principal Amo...

Example to see how to get user input and do with mathematical expressions- Example0004 In this example we are going to see how to get input from user, Mathematical expressions, For input we create an object from Class Scanner and with System.in Then we use method 'next' to get the input.  We will also see how the normal expression calculations are also done in Java // Input from keyboard, Mathematical expression package com.swprogramdeveloper; import java.util.Scanner; public class Main {     public static void main(String[] args) { // write your code here     // Constants         final float PI=3.14F;         float radius = 4.0F;         System.out.print("Please, enter radius of the circle : ");        //Scanner Class to get user input         Scanner radiusInput = new Scanner(System.in);        //NextFloat will read ...
