Patterns Problems

Question 1- Write a program to print following pattern – Enter the number of lines you want: 5 1 22 333 4444 55555

import java.util.*; class pattern { public static void main(String args[]) {     System.out.print("Enter the number of lines you want: ");     Scanner sc=new Scanner(System.in);     int n=sc.nextInt();     for(int i=1;i<=n;i++)     {         for(int j=1;j<=i;j++)         {             System.out.print(i);         }         System.out.println();     } } }

Question 2-  Write a program to print following pattern – Enter the number of lines you want: 5 1 12 123 1234 12345

import java.util.*; class pattern { public static void main(String args[]) {     System.out.print("Enter the number of lines you want: ");     Scanner sc=new Scanner(System.in);     int n=sc.nextInt();     for(int i=1;i<=n;i++)     {         for(int j=1;j<=i;j++)         {             System.out.print(j);         }         System.out.println();     } } }

Question 3- Write a program to print following pattern – Enter the number of lines you want: 5 * ** *** **** *****

import java.util.*; class pattern { public static void main(String args[]) {     System.out.print("Enter the number of lines you want: ");     Scanner sc=new Scanner(System.in);     int n=sc.nextInt();     for(int i=1;i<=n;i++)     {         for(int j=1;j<=i;j++)         {             System.out.print("*");         }         System.out.println();     } } }

Question 4- Write a program to print following pattern – Enter the number of lines you want: 5 1 21 321 4321 54321

import java.util.*; class pattern { public static void main(String args[]) {     System.out.print("Enter the number of lines you want: ");     Scanner sc=new Scanner(System.in);     int n=sc.nextInt();     for(int i=1;i<=n;i++)     {         for(int j=i;j>=1;j--)         {             System.out.print(j);         }         System.out.println();     } } }
