Here, we’re going to use a java.util.Scanner to run through the contents of the file and retrieve lines serially, one by one: FileInputStream inputStream = null; Scanner sc = null; try { inputStream = new FileInputStream(path); sc = new Scanner(inputStream, "UTF-8"); while (sc...
To read data and move on to the next line, we should use the nextLine() method. This method moves the scanner past the current line and returns the rest of the current line, excluding any line separator at the end. The read position is then set to the beginning of the next line. Si...

To convert a string to a long in Java, you can use the parseLong() method of the java.lang.Long class. This method parses the string as a signed decimal long, and returns the resulting long value.
input.next(); ... I'm sure you'd work it out. Though if you're still unable, you should move on from Scanner to other input Classes and methods. Check,https://www.geeksforgeeks.org/ways-to-read-input-from-console-in-java/Use BufferedReader class or Console class to do the same!
str1=scan.nextLine(); System.out.print("Enter Second String : "); str2=scan.nextLine(); if(str1.compareTo(str2)>0){ System.out.println("First String is Greater than Second String."); }elseif(str1.compareTo(str2)<0){ System.out.println("First String is Smaller than Second String...
Let’s delve into a complete working example that demonstrates how to use FileInputStream and DataInputStream to read and print the contents of a text file: import java.io.DataInputStream; import java.io.FileInputStream; import java.io.IOException; public class FileReadingExample { public stati...
