Program to display Digits in 7-Segment Style Using Java

Display Digits in 7-Segment Style Using Java

Ever wondered how digital clocks or calculators display numbers? They often use seven-segment displays—a simple arrangement of 7 LEDs to represent numbers from 0 to 9. In this post, we'll create a Java program that simulates the same effect on your console screen!

💡 What is a 7-Segment Display?

A 7-segment display is made up of seven LEDs (labeled a through g) that can be turned on or off to create numerical digits. Here's a visual representation:

Each digit is formed by turning on a combination of these segments.

The Seven segment display have 7 segments as shown below:

PROGRAM

import java.util.*;
public class DigitToSevenDisplay 
{
  public static void main(String[] args) throws Exception 
  {
    Scanner inr = new Scanner(System.in);
    int n = inr.nextInt();
    // Add the necessary code in the below space    
    switch(n)
    {
      case 0:
        System.out.println(" _ \n| | \n|_|");
        break;
      case 1:
        System.out.println("   \n  |\n  |");
        break;
      case 2:
        System.out.println(" _ \n _|\n|_ ");
        break;
      case 3:
        System.out.println(" _ \n _|\n _|");
        break;
      case 4:
        System.out.println("   \n|_|\n  |");
        break;
      case 5:
        System.out.println(" _ \n|_ \n _|");
        break;
      case 6:
        System.out.println(" _ \n|_ \n|_|");
        break;
      case 7:
        System.out.println(" _ \n  |\n  |");
        break;
      case 8:
        System.out.println(" _ \n|_|\n|_|");
        break;
      case 9:
        System.out.println(" _ \n|_|\n _|");
        break;
    }
  }
}
