Java program to calculate the simple interest Using 'Scanner' Class

Calculate the Simple Interest

The data needed to calculate simple interest can be initialized with the default value inside the class and also can be taken from the user. Here 'Scanner' class, the built-in class inside the 'util' package of 'java' project is imported to get value from the keyboard.

import java.util.Scanner; //Calling Scanner class to read input from Keyboard

public class SimpleInterest
{

     public static void main(String []args)
    {
         //Declaring Variables
         double Principal;
         double Time;
         double Rate;
         double Interest;

         System.out.println("Enter amount of Principle"); //Instruction for User
         Principal= new Scanner(System.in).nextDouble(); //Getting value for Principal from user

          System.out.println("Enter Time period"); //Instruction for User
         Time= new Scanner(System.in).nextDouble(); //Getting value of Time from user

          System.out.println("Enter Rate of Interest"); //Instruction for User
         Rate= new Scanner(System.in).nextDouble(); //Getting Interest Rate from user

          Interest= (Principal*Time*Rate)/100; //Processing
         System.out.println("Simple Interest =  "+Interest); //Printing Result
    }
}

Output:
     Enter amount of Principle
     1500
     Enter Time period
     2.5
     Enter Rate of Interest
     15.1
     
     Simple Interest =  566.25

Java program using Scanner Class

Scanner Class in Java The scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. It is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming. To create an object of Scanner class, we usually pass the predefined object System.in, which represents the standard input stream. We may pass an object of class File if we want to read input from a file. To read the numerical values of a certain data type XYZ, the function to use is nextXYZ(). For example, to read a value of type short, we can use nextShort() To read strings, we use nextLine(). To read a single character, we use next().charAt(0). next() function returns the next token/word in the input as a string and charAt(0) funtion returns the first character in that string Program to calculate import java.util.Scanner; //Calli...

Java program to print 'Hello World'

Simple program to print 'Hello World' This is the starting phase of the java program to print "Hello World". You can change the sentence inside the double quote sign like:- "Hello World" to "Hii This is my first java program", or anything according to your wish. public class  PrintHello {                public static void main(String []args)       {                              System.out.println (" Hello World  "); //Printing Hello                     } } Output of the above program is:  Hello World
