JAVA Patterns

Pattern questions in Java require some analysis on our part.

Here we notice that the first line cannot be set as a part of a loop. So we would print it as it is.

The NEXT 8 lines have their first digits in a pattern. In each of these 8 rows, the number is printed exactly once.

We run a loop, with say a variable i, for 8 times. And in each of these 8 times, we print i once, and the value of i+1 is then to be printed i times.

Here is a Java program for the same.

public class Pattern    //Creating Class

{

   public static VOID main(String[] ARGS)      //The main method

   {

       System.out.println("1");        //Printing the first line

       for(int i=1;i<9;i++)        //Setting the OUTER loop to run 8 times from 1 to 8

       {

           System.out.print(i+" ");    //Printing the value of i once

           int k=i+1;  //Setting k=i+1 for printing it i times

           for(int j=0;j

           {

               System.out.print(k+" ");    //Printing the value of k

           }

           System.out.println();       //Printing a blank line after each row

       }

   }

}
