Pattern Programs are combination of different types of patterns mixed with different characters or special characters. Pattern Program is frequently asked in Interviews for Freshers because the Organization/Company want to check Candidate’s Logical Skills as well as Coding Skills.We are collecting the some similar shape of pattern with different types in the Pattern Programs in Java (Set-1). I hope this post will help you.
There are other different types of pattern programs you should also learn:
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 numbers of rows : ");
int n = sc.nextInt();
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= n; j++) {
System.out.print("*");
}
System.out.println();
}
}
}Output:
Enter the numbers of rows : 6 ***** ***** ***** ***** ***** *****
Pattern 2 :
11111 22222 33333 44444 555555
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 numbers of rows : ");
int n = sc.nextInt();
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= n; j++) {
System.out.print(i);
}
System.out.println();
}
}
}Output:
Enter the numbers of rows : 5 11111 22222 33333 44444 555555
Pattern 3:
11111 12111 11311 11141 11115

int n = sc.nextInt();
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= n; j++) {
if (i == j) {
System.out.print(i);
} else {
System.out.print("1");
}
}
System.out.println();

}
}
}Output:
