Pattern Programs can be Number Pattern,Alphabets or Special Symbols.Pattern Program are frequently asked in Interviews for Freshers because the Organization/Company want to check Candidate’s Logical Skills as well as Coding Skills.This post is the collection of some similar shape of pattern with different types.I hope this post will definitely help you.
Pattern 1:
***** **** *** ** *
Pattern Program in Java:
import java.util.Scanner;
class Pattern_1 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of rows : ");
int n = sc.nextInt();
for(int i = n;i >= 1;i--){
for(int j = i;j >= 1;j--){
System.out.print("*");
}
System.out.println();
}
}
}Output:
Enter the number of rows : 5 ***** **** *** ** *
Pattern 2:
11111 2222 333 44 5
Pattern Program in Java:
import java.util.Scanner;
class Pattern_2 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of rows : ");
int n = sc.nextInt();
for(int i = 1;i <= n;i++){
for(int j = 1;j <= (n-i+1);j++){
System.out.print(i);
