Using Scanner Class In the above example, we had mentioned that, the inputs are taken making use of the scanner class. Scanner class in Java is that class which reads input at runtime given by the tester/user for any primitive datatype. So here, we make use of the scanner class to...
Our problem statement is to find the speed of internet. For this, our required inputs will be data in mega bytes (d) and time in minutes (t). We will make use of Scanner class in Java to read these inputs at runtime. Since, they are generally integers, which are primitive datatype...
Data in the file: First Line Second Line Third Line Fourth Line Fifth Line In the above example, we have used the BufferedReader Class to read the file named input.txt. Example 3: Java Program to Read File Using Scanner import java.io.File; import java.util.Scanner; class Main { public...

Program 1: Reverse a number using while Loop In this program, user is asked to enter a number. This input number is read and stored in a variablenumusingScanner class. The program then uses the while loop to reverse this number.
