12345

Answer 1

CODE 1:-

/*

11111    

1111      

111      

11        

1        

*/

class series5

{

   public static void main(String[] args)

   {

       for(int a=1;a<=5;a++)

       {

           int k=1;

           for(int b=a;b<=5;b++)

           {

               System.out.print(k);

           }

           System.out.println();

       }

   }

}

12

123

1234

12345

*/

class series6

{

   public static void main(String[] args)

   {

       for(int a=1;a<=5;a++)

       {

           for(int b=1;b<=a;b++)

           {

               System.out.print(b+" ");

           }

           System.out.println();

       }

   }

}

Important Point:-

• Always try to give shortest answer while Coding any program.
• Use Scanner class Or Buffer reader to ensure input through Keyboard means direct on Output screen.
• Scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings through keyboard. It is the easiest way to read input in a Java program.
• Always divide double data type variable with integer or integer data type from double data type variable.To ensure 100% result.
